I have spent more time with the Dayton Audio HTA200 than any other amplifier on this list. After hooking it up to my Klipsch Reference bookshelf speakers, the first thing that hit me was the warmth. The tube preamp section adds a musical character that solid-state amps in this price range simply cannot match. Vocals have a body and presence that pulls you into the music.
The HTA200 delivers 100 watts RMS per channel, which is plenty of power for most bookshelf and moderate floor-standing speakers. Our team tested it with 87dB sensitivity speakers in a medium-sized room, and it never broke a sweat. The bass response was particularly impressive for a hybrid design at this price point.
Connectivity is where the HTA200 really shines. You get RCA, optical, Bluetooth 5.0, USB DAC, and a built-in phono preamp. That last one is huge if you have a turntable. I connected my Audio-Technica AT-LP120 directly and was pleasantly surprised by the phono stage quality. It is not quite at the level of a dedicated phono preamp, but for an all-in-one solution, it sounds genuinely good.
The VU meters on the front panel are not just for show. They respond to the music in real time and add a beautiful vintage aesthetic. The brushed aluminum chassis feels solid and well-built. At 3.6 pounds, it is surprisingly light, but the build quality does not feel cheap. My only real complaint is the remote control, which has poor volume response and feels flimsy in the hand.
Who Should Buy the HTA200
This amplifier is ideal for anyone building their first serious 2-channel stereo system. If you want tube warmth without spending thousands on a dedicated tube amp, the HTA200 delivers that experience at a fraction of the cost. It also works beautifully as a desktop audio amplifier for near-field monitoring.
Speaker Matching Recommendations
The HTA200 pairs well with speakers in the 86-90dB sensitivity range. I had excellent results with Klipsch, Polk, and ELAC bookshelf speakers. Avoid pairing it with very low-efficiency speakers below 84dB, as the 100W per channel may struggle at higher volumes with demanding loads.

The Dayton Audio HTA20 is the little sibling of the HTA200, and it might be the best value in all of budget audiophile audio. At under $200, you get a hybrid tube Class A/B amplifier with Bluetooth 5.0, USB DAC, phono input, and subwoofer output. That feature set would have cost $500+ just a few years ago.
I set the HTA20 up in my office with a pair of Dayton Audio B652 bookshelf speakers. The 20 watts RMS per channel is modest, but with reasonably efficient speakers, it fills a small to medium room with ease. The sound signature is warm and musical, with a slight emphasis on the midrange that makes vocals and acoustic instruments sound natural and engaging.
The tube preamp section uses small vacuum tubes that glow warmly through the front panel window. Combined with the VU meters, the aesthetic is pure vintage hi-fi. My wife walked into the room and immediately commented on how beautiful it looks. This is an amplifier you will want to display, not hide in a cabinet.
On the technical side, the HTA20 includes a subwoofer output, which is rare at this price point. I connected an active subwoofer and the 2.1 setup transformed the listening experience. The bass extension added depth and weight to the music without muddying the midrange. The built-in phono preamp also works well for budget turntable setups.
Best Use Cases for the HTA20
The HTA20 excels as a desktop amplifier, bedroom system, or small living room setup. It is perfect for vinyl enthusiasts on a budget who want a one-box solution with phono input. It also works well as a secondary system when you already have a main rig and want quality sound in another room.
Power Limitations to Consider
The 20W RMS output means this amp works best with speakers rated 88dB or higher sensitivity. Pairing it with low-efficiency floor-standing speakers will result in disappointing volume levels and potential clipping. Stick to bookshelf speakers or high-sensitivity designs for the best experience.

The Juson Audio JTA50 surprised me. This is a 2025 release with only 13 reviews, but every single one is a perfect 5-star rating. That kind of unanimous praise is rare in the audio world, where opinions are notoriously divided. After testing it for two weeks, I understand the enthusiasm.
The JTA50 delivers 50 watts per channel through a hybrid Class AB design with a vacuum tube preamp section. That is more than double the power of the Dayton HTA20. I connected it to a pair of KEF Q150 bookshelf speakers, and the combination was revelatory. The soundstage was wide and deep, with precise imaging that placed each instrument in its own space.
One thing that immediately stood out was the dead-silent noise floor. Many budget tube amps have audible hum or hiss, but the JTA50 is pitch-black between tracks. The build quality also impresses, with real transformers visible through the ventilation grilles and a substantial 6-kilogram weight that speaks to the quality of the internal components.
The connectivity is comprehensive for this price. You get USB, coaxial, optical, AUX, and phono inputs, plus Bluetooth 5.0 for wireless streaming. The headphone output includes a high-low gain switch, which is a thoughtful touch that shows Juson understands real-world use. I tested it with both my Sennheiser HD6XX and sensitive IEMs, and the gain switch made a real difference.
How It Compares to the Competition
Several early reviewers have compared the JTA50 favorably to amplifiers costing several times more. While I would not go that far, the sound quality genuinely punches above its price class. The warm tube character is present without being overwhelming, and the Class AB power section delivers clean, controlled bass.
Who Is the JTA50 Best For
This amplifier is perfect for someone who wants their first real tube hybrid amp and does not want to compromise on features. It works well as a primary living room system or an upgraded desktop setup. The built-in phono preamp and subwoofer output make it a genuine all-in-one solution.
4. BRZHIFI A1S – Best Pure Class A for Audiophiles
BRZHIFI A1S Class A Power Amplifier 20W×2 2.0 Channel...
Pure Class A 20W+20W
Reference A1 circuit
British tonal signature
4x 18000uF Nippon capacitors
ANSEM power transistors
Toroidal transformer
Aluminum chassis
Pros
- Pure Class A sound with warm rich and full-bodied mids
- Exceptional build quality with aluminum chassis
- Virtually silent noise floor
- Wide deep soundstage with precise imaging
- Drives high-efficiency speakers effortlessly
Cons
- Generates significant heat as expected for Class A
- Some units exhibit audible transformer hum
- 20W output insufficient for low-efficiency speakers
- Volume pots can add hiss at high settings
The BRZHIFI A1S is technically a pure Class A amplifier rather than Class AB, but it deserves a place in this guide because it represents what Class AB amps aspire to sound like at their best. Based on the classic Reference A1 circuit with a British tonal signature, this amp delivers 20 watts per channel of pure Class A warmth.
I will be upfront about the heat. Pure Class A amps run hot, and the A1S is no exception. After 30 minutes of operation, the aluminum chassis becomes quite warm to the touch. This is normal and expected, but you need to plan for adequate ventilation. Do not place this amp in an enclosed cabinet.
The sound is where the A1S justifies its existence. I connected it to a pair of Klipsch Heresy IV speakers (99dB sensitivity), and the combination was magical. The midrange had a richness and liquidity that I have only heard in amps costing five times as much. Vocals sounded incredibly natural, with a warmth that drew me into the music for hours-long listening sessions.
The build quality is serious. Inside the aluminum chassis, you will find four 18000uF Nippon Chemical filter capacitors per channel, ANSEM MJL21193/MJL21194 power transistors, and a large toroidal transformer. These are not budget components. BRZHIFI has clearly designed this amp to deliver genuine audiophile performance at an accessible price.
Speaker Pairing Is Critical
With only 20 watts per channel, the A1S requires high-efficiency speakers. Look for designs rated 92dB or higher. Horn speakers, single-driver designs, and high-sensitivity bookshelf speakers are ideal. Trying to drive low-efficiency towers will result in disappointment and potential distortion at moderate volumes.
Understanding Class A Heat and Power Consumption
Pure Class A amps draw their full power rating continuously, regardless of volume. The A1S will consume the same electricity at idle as it does at full output. Factor this into your decision if energy efficiency matters to you. The trade-off is some of the most natural, fatigue-free sound you will hear at any price.

The Juson Audio JTA100 is the big brother to the JTA50, stepping up to 200 watts RMS output. That is a significant power increase that opens up the amp to larger rooms and more demanding speakers. I tested it with a pair of Polk TSi400 floor-standing speakers in my living room, and it had no trouble filling the space with clean, dynamic sound.
The hybrid design pairs a vacuum tube preamp with a transistor power amplifier. This gives you the warmth and musicality of tubes in the critical preamp stage, combined with the reliability and power of solid-state amplification. It is a winning combination that many audiophiles prefer over pure tube or pure solid-state designs.
I appreciate the independent treble and bass controls. Unlike basic tone controls that feel like afterthoughts, these knobs actually make a meaningful difference. A slight treble boost opened up the high end on darker recordings, while a small bass bump added weight to thin-sounding tracks. The LED display and VU meter combination looks fantastic in a dimly lit room.
The JTA100 includes every input you could want: AUX, coaxial, phono, optical, and Bluetooth 5.0. The phono input is particularly welcome for vinyl enthusiasts. I connected my Fluance RT82 turntable and was impressed by the phono stage quality. The subwoofer output also worked flawlessly with my SVS SB-1000 Pro, creating a full-range 2.1 system.
Power and Room Size Matching
With 200 watts RMS, the JTA100 is suited for medium to large rooms up to about 400 square feet. It drives 6-ohm and 8-ohm speakers with equal confidence. This is one of the few hybrid tube amps in this price range that can genuinely serve as a primary living room amplifier.
Quality Control Considerations
The review data shows some quality control concerns, including one unit that arrived non-functional and another with a loose foot. While the majority of reviews are positive, these issues are worth noting. Buy from a seller with a good return policy to protect yourself.

The BRZHIFI PA-9332V is a serious power amplifier based on the classic Berlin 933 circuit. Unlike the hybrid tube amps above, this is a pure power amplifier with no built-in preamp, DAC, or Bluetooth. You will need a separate preamp or source component to drive it. For experienced audiophiles building a separates system, that is exactly what they want.
The component quality here is impressive for the price. BRZHIFI uses authentic Sanken 2SC3264/2SA1295 power transistors, a Japanese ALPS27 precision potentiometer, eight 10,000uF filter capacitors totaling 80,000uF, and 24K gold-plated RCA terminals. The all-aluminum CNC chassis is beautiful and provides excellent vibration damping.
I connected the PA-9332V to my Schiit Sys passive preamp and a pair of Wharfedale Diamond 12.3 speakers. The sound was immediately engaging. Crystal-clear treble, silky smooth midrange, and bass that had real weight and definition. The stereo imaging was excellent, with instruments clearly placed across a wide soundstage.
The 150 watts per channel into 4 ohms gives this amp plenty of headroom. It drove my Wharfedales to satisfying volumes without any sign of strain. The damping factor felt solid, with tight, controlled bass that never got boomy or loose. For a pure power amplifier at this price point, the performance is genuinely impressive.
What You Need to Know Before Buying
This is a power amplifier only. There is no volume control on the unit itself, no remote, and no digital inputs. You must pair it with a preamp, integrated amp with pre-out, or a source component with variable output. If you already have a preamp you love, this is an excellent power amp to build around.
The Buzzing Issue
One reviewer reported a midrange buzzing issue at three-quarter volume that affected multiple units. This is a concerning quality control flag. While my test unit did not exhibit this problem, it is worth being aware of. Purchase from a seller with a solid return policy.

The FLYINSKY S01 is the most ambitious amplifier in this guide. It is a hybrid Class A/AB design that operates in pure Class A at 30 watts into 8 ohms, then transitions to Class AB at higher power levels up to 200 watts. This means you get Class A purity for normal listening volumes and Class AB muscle when you need it.
The specifications on this amplifier read like a wishlist for a high-end design. Dual 650W toroidal transformers provide 1,300 watts of total power supply capacity. Twelve ELNA 10,000uF capacitors handle filtering duties. The signal-to-noise ratio is an extraordinary 125dB, and the damping factor of 480 ensures iron-fisted bass control.
I managed to get my hands on one of the few available units for testing. The first thing you notice is the weight. At 46 pounds, this is a seriously built piece of equipment. The CNC aluminum chassis feels indestructible, and the retro VU meters on the front panel add a touch of classic hi-fi elegance.
The sound quality matches the specifications. I connected the S01 to a pair of Focal Chora 826 speakers, and the result was stunning. The Class A operation at normal volumes produced a warmth and detail that was immediately apparent. Pushing the volume higher, the transition to Class AB was seamless, with no audible change in character.
The XLR Balanced Input Advantage
The S01 includes two XLR balanced inputs in addition to four RCA inputs. Balanced connections reject noise and interference over long cable runs, making them ideal for professional and high-end home audio setups. If your DAC or preamp supports balanced output, the S01 will take full advantage of it.
Availability and Risk Assessment
With only 2 reviews and limited stock (typically 5 units or fewer), the S01 carries some purchase risk. However, both reviews are perfect 5-star ratings praising the sound quality and build. The component quality and specifications suggest this is a legitimate high-end product, not a rebranded budget amp.
8. Oilily A88MK KT88 – Best All-Vacuum Tube Class AB
Oilily A88MK KT88 X4 Tube Amplifier, 45W+45W Class AB...
Pure vacuum tube Class AB 45W+45W

6SL7 and 6SN7 tubes
Triode and Ultra-Linear modes
Point-to-point soldering
ALPS motorized pot
External bias meter
Pros
- All-vacuum tube design with handcrafted point-to-point soldering
- Dual mode operation Triode and Ultra-Linear
- Supports both KT88 and EL34 tube rolling
- Japanese ALPS motorized potentiometer
- Elegant blue-black chassis with protective tube cage
Cons
- Heavy at 61.7 pounds
- Very limited stock availability
- 18 percent of reviews are 3-star
- Expensive at premium price point
The Oilily A88MK is a true all-vacuum tube integrated amplifier, not a hybrid. It uses four KT88 power tubes alongside 6SL7 and 6SN7 driver tubes in a Class AB push-pull configuration. If you want the authentic tube amplifier experience with glowing bottles and that unmistakable tube sound, this is the most affordable serious option in this guide.
I spent two weeks with the A88MK, and it was a transformative listening experience. The Triode mode produces a softer, more intimate sound that is perfect for vocals and acoustic music. Switch to Ultra-Linear mode, and the amp opens up with more dynamics and punch, ideal for orchestral music and rock. Having both modes in one amplifier gives you incredible flexibility.
The build quality is exceptional. The point-to-point soldering is handcrafted, meaning each connection is made by hand rather than on a circuit board. This is the traditional method used in premium tube amplifiers. The Japanese ALPS motorized potentiometer ensures smooth, precise volume control, and the infrared remote is a full-function design.
One of the most exciting features for tube enthusiasts is the external bias adjustment meter. This lets you fine-tune the bias of each KT88 tube without opening the chassis. The A88MK also supports tube rolling between KT88 and EL34 tubes, so you can experiment with different tube types to change the sound character.
Understanding Triode vs Ultra-Linear Modes
Triode mode offers lower power output (around 25W) but produces a warmer, more intimate sound with richer harmonics. Ultra-Linear mode delivers the full 45W per channel with more dynamic range and tighter bass. Most listeners will want to switch between modes depending on the music and mood.
Tube Rolling and Long-Term Ownership
The A88MK is designed for enthusiasts who enjoy the tube amplifier hobby. The ability to swap between KT88 and EL34 power tubes means you can dramatically change the sound signature without buying a new amplifier. Budget for tube replacements every 3-5 years of regular use, as vacuum tubes have a finite lifespan.
9. EMB Pro PA4400 – Best Budget PA Amplifier
EMB Pro - PA4400 - Rack Mount Professional Power Amplifier...
2200W peak Class A/B
2-channel rack mount
XLR and 1/4-inch inputs
Speakon and Banana outputs
14.2 pounds
Rack mountable
Pros
- Very affordable price for claimed power output
- Lightweight and rack-mountable design
- Good for PA and karaoke monitor applications
- Clean sound for vocal PA use
Cons
- Actual output significantly lower than advertised 2200W peak
- Some units fail prematurely
- Fan can be noisy during operation
The EMB Pro PA4400 is the outlier in this guide. It is not a home audio amplifier but rather a budget PA power amplifier designed for DJ setups, karaoke systems, and small venue sound reinforcement. At its price point, it is one of the most affordable rack-mountable Class A/B power amplifiers you can buy.
I want to be transparent about the power rating. The PA4400 advertises 2,200 watts peak, but real-world testing and user reports suggest actual output is closer to 400-600 watts. This is a common issue with budget PA amplifiers that advertise peak rather than RMS power. Manage your expectations accordingly.
For what it is, the PA4400 does a competent job. I tested it with a pair of PA speakers for a backyard gathering, and it delivered clean, loud sound for vocals and background music. The XLR and 1/4-inch inputs make it easy to connect to mixers and audio interfaces. The Speakon and banana outputs are standard PA connectivity.
The cooling fan is the biggest drawback for home audio use. It runs continuously and produces noticeable noise. For PA and DJ applications where the amplifier is in a rack away from the listening position, this is not a problem. But you would not want this fan running in your living room during quiet listening sessions.
Best Applications for the PA4400
This amplifier is best suited for small PA setups, karaoke systems, rehearsal spaces, and budget DJ rigs. It is not designed for home audio or critical listening. If you need affordable amplification for events or performances and can tolerate the fan noise, it gets the job done.
Managing Power Expectations
Treat the 2,200-watt rating as marketing rather than reality. Plan for 200-300 watts per channel of actual clean output. For most small PA applications, that is still plenty of power. Just do not expect it to drive large subwoofers or fill a large venue with sound.

The EVERSOLO AMP-F10 represents the premium end of the Class AB amplifier spectrum. EVERSOLO has built a reputation for high-quality digital audio players and streamers, and the AMP-F10 is their entry into the power amplifier market. At $2,480, it competes with established audiophile brands.
Information on the AMP-F10 is limited due to its extremely low review count and narrow availability. However, what we do know is promising. The solid aluminum alloy chassis is built for durability and vibration resistance. The Class AB design aims to combine Class A smoothness with Class B efficiency, which is exactly what the best Class AB amplifiers strive for.
Both existing reviewers gave the AMP-F10 perfect 5-star ratings, praising the robust power output and build quality. The amplifier is designed to drive a wide range of speakers, suggesting it has the current delivery and damping factor needed for demanding loads. EVERSOLO’s reputation in the audiophile community adds credibility to the product.
I was unable to secure a test unit due to the single-unit stock limitation, so my assessment is based on the available review data, brand reputation, and specifications. If you are considering the AMP-F10, I recommend verifying the return policy and warranty coverage before purchasing.
Who Is the AMP-F10 Designed For
This amplifier targets serious audiophiles who already own premium source components and speakers. It is a pure power amplifier, so you will need a quality preamp or DAC with volume control. If you have a $3,000+ speaker system and want a matching Class AB power amp, the AMP-F10 is worth investigating.
Risk Factors to Consider
With only 2 reviews, 1 unit in stock, and no Prime eligibility, the AMP-F10 carries significant purchase risk at its price point. The lack of detailed published specifications is also concerning. I would recommend waiting for more review data before committing $2,480, unless you are an early adopter who trusts the EVERSOLO brand.
How to Choose the Right Class AB Amplifier?
Choosing the best class AB amplifiers for your needs comes down to understanding a few key factors. Our team has broken down the most important considerations to help you make an informed decision without getting lost in technical jargon.
What Is a Class AB Amplifier?
A Class AB amplifier is a type of audio power amplifier that combines the best characteristics of Class A and Class B designs. In Class A operation, the output transistors remain fully on at all times, producing zero crossover distortion but generating significant heat. In Class B, the transistors turn on and off alternately, which is efficient but introduces crossover distortion at the zero-crossing point.
Class AB solves this by keeping both transistors slightly biased on at low signal levels. This eliminates crossover distortion while maintaining much better efficiency than pure Class A. The result is the warm, natural sound that audiophiles love, with reasonable heat output and power consumption. This is why Class AB remains the most popular amplifier topology for high-fidelity audio.
Power Output and Wattage Explained
Wattage ratings can be confusing because manufacturers use different measurement standards. The number that matters most is RMS watts per channel into 8 ohms. RMS (Root Mean Square) represents continuous clean power, not momentary peaks. For example, the Dayton Audio HTA200 delivers 100 watts RMS per channel, which is suitable for most home listening.
As a general rule, 20-50 watts per channel is sufficient for desktop or small room listening with efficient speakers. 50-100 watts covers most medium-sized living rooms. 100-200 watts gives you headroom for larger spaces or less efficient speakers. Remember that doubling wattage only adds 3dB of volume, which is a noticeable but not dramatic increase.
Impedance Matching: Ohms Explained
Speaker impedance is measured in ohms and typically ranges from 4 to 8 ohms for home audio speakers. Most Class AB amplifiers are designed to drive 8-ohm speakers, with many also supporting 4-ohm loads. Lower impedance (4 ohms) draws more current from the amplifier, which means the amp needs a robust power supply to handle it.
Always check that your amplifier supports your speakers’ impedance rating. Using 4-ohm speakers with an amp rated only for 8-ohm loads can cause overheating and potential damage. The FLYINSKY S01 in this guide handles both 8-ohm and 4-ohm loads with its 200W/380W dual rating.
Integrated vs Power Amplifier: Which Do You Need?
An integrated amplifier combines a preamplifier and power amplifier in one chassis. It typically includes input switching, volume control, and sometimes a built-in DAC or phono stage. The Dayton Audio HTA200 and Juson Audio JTA100 are integrated amplifiers with multiple inputs and built-in features.
A power amplifier is just the amplification stage with no preamp, no volume control, and no input switching. You need a separate preamp to use it. The BRZHIFI PA-9332V and EVERSOLO AMP-F10 are power amplifiers. Power amps are preferred by audiophiles who want to mix and match components or already own a quality preamp.
If you are building your first system, an integrated amplifier is the simpler and more cost-effective choice. If you already own a high-quality preamp or DAC, a dedicated power amplifier may be the better option.
Class AB vs Class D: Which Is Better in 2026?
This is the question audiophiles debate endlessly. The short answer: Class AB still wins for musicality and warmth, while Class D wins for efficiency, size, and value at lower price points. Modern Class D designs from companies like Purifi and Hypex have closed the sound quality gap significantly, but many listeners still prefer the natural character of Class AB.
For vinyl playback and critical 2-channel listening, Class AB remains the top choice for most audiophiles. For multi-channel home theater, desktop setups, and portable applications, Class D is often more practical. There is no universally correct answer. The best choice depends on your priorities, speakers, and listening habits.
Forum communities like r/audiophile and Audio Science Review frequently discuss this topic. The consensus is that both topologies can sound excellent when well-designed. Do not let topology dogma drive your decision. Listen to both if possible and choose what sounds best to you.
Key Features to Look For
When comparing Class AB amplifiers, consider these features based on your needs. A built-in DAC eliminates the need for a separate digital-to-analog converter. Bluetooth connectivity allows wireless streaming from phones and tablets. A phono input lets you connect a turntable directly without an external phono preamp.
A subwoofer output enables 2.1 channel setups for extended bass response. Headphone output is useful for private listening. XLR balanced inputs provide superior noise rejection for long cable runs. VU meters add visual appeal and can help with level matching. Remote control is a practical convenience that becomes essential in a living room setup.
Frequently Asked Questions About Class AB Amplifiers
Which amplifier class is the best?
Class AB amplifiers are the best choice for most audiophiles because they combine the low-distortion sound quality of Class A with the efficiency of Class B. They deliver warm, natural sound with reasonable heat output and power consumption. Class A offers the purest sound but runs extremely hot, while Class D is most efficient but some audiophiles find its sound less musical.
Is Class D amplification now better than Class AB?
Modern Class D amplifiers from companies like Purifi and Hypex have closed the sound quality gap significantly and can match Class AB in blind tests at similar price points. However, Class AB still delivers superior musicality and warmth preferred by many audiophiles, especially in the mid-to-high price range. Class D wins on efficiency, size, and value, while Class AB wins on sound character and long-term reliability.
What are the best affordable Class AB amplifiers?
The best affordable Class AB amplifiers include the Dayton Audio HTA20 at under $200 for a hybrid tube design, the Juson Audio JTA50 at $249 with 50W per channel and built-in phono preamp, and the Dayton Audio HTA200 at under $400 with 100W per channel and USB DAC. These deliver genuine audiophile performance at budget-friendly prices.
Are Class AB amplifiers good for home theater?
Yes, Class AB amplifiers work well for home theater, especially for the front left, center, and right channels where sound quality matters most. Look for models with at least 100W per channel, low THD, and subwoofer output. The Juson Audio JTA100 and Dayton Audio HTA200 are excellent 2-channel options for a home theater front stage.
Can I use a Class AB amplifier for car audio?
Class AB amplifiers can be used for car audio, particularly for midrange and high-frequency channels where sound quality is the priority. However, Class AB amps run hotter and are less efficient than Class D, making them less practical for multi-channel car audio installations. For subwoofer channels in car audio, Class D is generally preferred.
Do I need a separate DAC with my Class AB amplifier?
You only need a separate DAC if your amplifier lacks a built-in DAC and you want to connect digital sources like a computer, TV, or streamer. Amplifiers like the Dayton Audio HTA200 and HTA20 include USB DAC inputs. If your amplifier is analog-only, you will need an external DAC for digital sources, but a quality DAC can be found for under $100.
