What are hifi reviews useful for? (1) Identifying products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've heard (this means they probably are legitimately great). (3) Identifying a product's attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we often discount what reviewers say because they heap praise on most products—and are often apprehensive about publishing strong criticism or comparisons between products. Further, they seldom have more than a few products on-hand, often relying on their memories to compare past products. Always listen for yourself.

Our summary
Product Strengths
- Delivers a clean and detailed sound, allowing listeners to hear nuances in recordings
- Offers good instrument separation and imaging
- Has a low noise floor, creating a 'black background' and enhancing the listening experience
- Compact size for an A-B amplifier
- Does not have RCA inputs, requiring XLR or TRS balanced connections
Product Considerations
- May not have enough power for inefficient speakers or large rooms
- External power supply 'brick' is large
- No remote control
Comparisons (according to reviewers)
- The LA90 has a more neutral sound than Cambridge Audio AXA25, which is cleaner and more detailed
- The LA90 comes close to Benchmark AHB2's performance, but does not outperform it in bass impact and soundstage size, and the AHB2 also has more protection systems
- The LA90 offers more vocal clarity and fuller bottom end than Schiit Vidar, but the Vidar is more exciting on top
- Emotiva A1's have more power
Takeaway: The Topping LA-90 Discrete is a small amplifier that produces very clear sound with good detail, making it great for those who already have balanced audio equipment. It could be a nice upgrade for those seeking to hear all the subtleties in their music.

Expand Details
Product Strengths
- Impressive specs and measurements showcase extremely low noise and distortion
- Clean and transparent sound aims for a neutral reproduction of music
- Compact size and sleek design make it suitable for small spaces
- CNC machined aluminum chassis allows for maximum thermal flow to keep the unit running cool
Product Considerations
- Included external power supply is large and heavy, which can be a challenge to hide
- Power output may be limiting, especially with demanding speakers and for high dynamic range tracks
- Bass performance, while tight and controlled, may lack sub-bass extension and impact for some listeners
- Lack of a remote control limits its convenience as an integrated amplifier
Comparisons (according to reviewers)
- The Discrete version matches the Topping LA90 IC based unit's exemplary performance, but betters it in power handling
- The Topping LA90 comes close to the Benchmark AHB2 in noise floor and detail retrieval, but the AHB2 has more power, impactful bass, and a bigger soundstage
Takeaway: The Topping LA90 is a compact and technically proficient amplifier that delivers a clean and transparent sound and with impressive specs. It is best suited for those with efficient speakers and a preference for accurate sound reproduction without coloration.

Our Summary
Product Strengths
- Very well-built and feels solid and heavy for its size
- Uses high-quality components such as Japanese Alps potentiometer, Omron relay, Nover Gold Audio capacitors, and Toshiba transistors
- Has a toroidal transformer that is considered overkill for its power output, which is a positive thing
- Has a warm sound signature, sometimes described as tube-like
Product Considerations

- Only has one set of RCA inputs, which may limit connectivity for some users
- Some reviewers found the 50 watts per channel to be lacking punch with certain speakers
- Has no remote, digital inputs, streaming capabilities, or phono stage
- The gold color of the chassis may not appeal to everyone
Comparisons (according to reviewers)
- Fosi Audio HD-A1 is slightly cleaner with a lower noise floor than the Emotiva A300, but lacks the punch
- Paired with infinity intermezzo 4.1 T speakers, the Fosi Audio HD-A1 sounds better than the Marantz nr1200 powering Sony SSCS5 speakers
- The Fosi Audio HD-A1 has a similar clean, powerful class A/B signature as the Emotiva A300, but with a touch of warmth

Product Strengths
- Easy sound that's far better than one might expect for a product this inexpensive
- Dynamics are especially good, and there's plenty of dynamic swing
- Top end was exceptionally smooth and musical
- Fosi is small, but it seems solidly put together
Product Considerations
- When being driven by any of the digital inputs, the DA2120D would emit a burst of varying durations that sounded almost like white noise
