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
- Compact size and respectable heft make it suitable for desktops and small spaces
- Clean and clear sound with good detail retrieval, leaning slightly towards warm, but not overly so
- Enough power to drive moderately sensitive speakers well, especially in nearfield setups
- Features a headphone jack that shunts power from speaker outputs, and gain adjustments for customized sound
- Offers versatile connections for multi-room setups, including power triggers and loop outs
Product Considerations
- Treble presentation is on the forward side of neutral, with a little extra energy, which may not suit all preferences
- Speaker terminals are close together, which may cause issues with shorting if using spades or thick bare wire
- Not ideal for very high efficiency speakers due to a potentially audible noise floor
- May lack dynamic punch with low sensitivity speakers in larger listening spaces
Takeaway: The Parasound ZoneAmp V3 is a well-built and compact amplifier that offers a clean and detailed sound, suitable for desktop or small room use. Its versatile features and surprising sound quality make it a great option for those seeking a no-nonsense amplifier.
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.

/
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.
