What reviewers think
Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.
Product Strengths
- Delivers 95 watts RMS per channel into 8 ohms (all channels driven) and 130 watts RMS into 4 ohms
- Features a heavy-duty linear power supply and high quality class A-B amplification
- Has transparent fall protection, and both a trigger input and output for daisy-chaining amps
- Simple, modern aesthetic with a brushed aluminum faceplate and a clean internal layout
- Excellent dampening factor of greater than 500 into an 8 ohm load for great low end control
Product Considerations
- The power rating of 130 watts RMS per channel into 4 ohms is only true at 1 kilohertz, not the entire spectrum
- At 4 ohms load, the total harmonic distortion is higher compared to 8 ohms
- Though cooling fans are used, they are barely audible unless you are right next to the amp
Comparisons (according to reviewers)
- Vs Marantz MA500 Monoblocks: BasX A5 had similar channel separation and a slightly more neutral upper end, giving more detail and openness without harshness
- Vs Emotiva UPA1 Monoblocks: Similar sound, but the monoblocks have more headroom, especially for large power-hungry towers without a sub
- Vs Yamaha AV receiver's built-in amps: Marked improvement in sound quality
Takeaway: The Emotiva BasX A5 is a great multi-channel amp that adds clean power to a home theater system without compromising sound quality. It's an affordable way to improve the audio experience, especially when paired with an AV receiver.
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.

Expand Details
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

/
Released
2021
Hi-Fi companies are spoiling headphone enthusiasts with a wide range of choices, but they often overlook near-field audiophiles who listen to speakers in small studios or from their desktops. Instead, near-field audiophiles are left with subpar Class-D amps or active speakers. Alternatively, they have to settle for larger Class-AB amps that disrupt the aesthetic of their setups. The Burson Funk breaks that rule by offering a combination of exceptional performance and a design that fits seamlessly into any living space.
Burson is a hifi brand recognized for its modular op-amp design that allows users to easily swap components to customize their sound signature.
Expand Details
Our Summary
Product Strengths
- Good sound quality, especially in the midrange, leads to vivid and well-formed vocals
- Versatile, it works well with both efficient headphones/IEMs and moderately powered speakers
- Compact design and good build quality, with the chassis acting as a heatsink
- Ability to roll op amps allows users to customize the sound signature
- Ample power for most headphones and nearfield speaker setups
- Only one RCA input, which may be limiting for some users
Product Considerations
- Speaker amplifier power (35-45W) might be insufficient for power-hungry speakers or larger rooms
- The base model op amps are sonically inferior to upgrade options
- Mild turn-off thump present
Comparisons (according to reviewers)
- The Funk has a narrower but deeper soundstage with better imaging and layering than the Arylic A08 Pro
- The Funk has superior imaging, but less potential power output depending on the Arylic's power supply than the Arylic A07/A08 Pro
- The Funk is preferred for desktop speaker setups with Vivid opamps when compared to Schiit Aegir
Takeaway: The Burson Funk is a solid choice for people wanting good sound from both their headphones and speakers in a single, convenient unit. The ability to change the sound by swapping op amps is a welcome feature for those who like to tinker and upgrade.
