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

  • Solid build quality, feeling dense and sturdy
  • Flagship-grade DAC chip and swappable op-amps allow for customizable sound
  • Fantastic clarity and details with immaculate note presentation, clean and clear with excellent precision
  • Plenty of power to handle demanding headphones like planars and full-size models
  • Sound profile enhances separation, articulation, and improves depth of field

Product Considerations

  • The digital display could be bigger, as the letters are hard to see from a distance
  • Volume knob might not respond to every step, especially when moving the dial fast
  • Lacks analog inputs, limiting its ability to be paired with standalone DACs or analog sources
  • Gets warm during usage

Comparisons (according to reviewers)

  • The Playmate 2 has a deeper, wider and more holographic sound than the SMSL DO400, with less focus on the midrange, which brings forward dynamics and details more
  • Higher driving power of the Burson results in much better control than the EverSolo DAC-Z6, with lower THD and lower distortions, a much more dynamic sound, and better overall impact and details

Takeaway: The Playmate 2 is a versatile DAC/Amp with excellent clarity and power, suitable for a wide range of headphones and even for gaming. It offers a clean and detailed sound with the added benefit of customizable sound via swappable op-amps.

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.

Brand highlights

Taking a step back to look at reviewers' thoughts of the brand's entire lineup—not just this product—what stands out most is the following:

  • Burson distinguishes itself by utilizing fully discrete, pure Class-A amplifier designs, deviating from the integrated circuits (ICs) commonly found in other brands.
  • They incorporate swappable op-amps, which are not soldered to the circuit board, providing users with the ability to fine-tune the sonic characteristics of their equipment, making them customisable.
  • They developed their proprietary Max Current Power Supplies (MCPS) to enhance dynamic range and reduce noise, setting them apart from competitors that use standard switching transformer designs.
  • Burson is known for its powerful, engaging sound signature, often described as warmer, punchier, and more dynamic, differing from the more neutral or analytical presentations of other brands.

Voyager

  • Positioning: Positioned as a high-end headphone amplifier and preamplifier in Burson Audio's lineup.
  • Description: Offers a rich, full-bodied sound with excellent dynamics. Its dual mono Class-A design and custom cooling system set it apart from other products, providing superior soundstage and detail compared to the Performance series.

Party

  • Positioning: Burson Audio's entry-level line, designed for affordability and compactness.
  • Description: Fun and compact, featuring key technologies from Burson's higher-end models. While it lacks the power and refinement of the Performance series, it offers a versatile and energetic sound, making it a great choice for casual listeners or those with budget constraints.

Performance

  • Positioning: A mid-range offering, providing a balance between price and high-quality audio performance.
  • Description: Known for its engaging and dynamic sound, features a powerful Class-A output stage that enhances its sonic capabilities. Compared to the Party series, it offers a more refined sound with better detail and resolution.

Our take on the brand

Burson is a hifi brand recognized for its modular op-amp design that allows users to easily swap components to customize their sound signature.

Look inside the brand

Brand Page

Our interview with the brand

What are two key technological innovations or strong opinions that differ you from other brands?

Modular, Upgradeable Designs

We believe great gear should evolve with your system. That's why our products feature swappable opamps and power modules — letting users fine-tune performance or upgrade later without buying a whole new unit.

Pushing Class-A to New Heights

All our amplifiers operate in pure Class-A with high idle bias to achieve an effortless, dynamic sound.

What's your approach to customer support?

We love working directly with our customers — it's one of the best parts of being a small, passionate team. Customers can always reach out to us directly or go through their local dealer if they prefer. What to expect:

  • Fast and personal responses
  • Worldwide service centers (AU, EU, US, HK) to keep support convenient
  • Trade-in options for older gear
  • And even tips for mods and tweaks

What are your favorite tracks for showcasing the strength of your products?

"Vincent" – Sara K (from Are We There Yet): A stunning vocal performance with incredible acoustic detail.

"Don't Know Why" – Norah Jones: Her voice reveals micro-detail and tonal balance instantly.

"Limit to Your Love" – James Blake: Sub-bass extension, dynamics.

What other products pair best with yours?

We've had nearly 20 years of working relationship with Audeze, and our US facility — although it's changed address a few times — has always been close to Audeze's in California. Naturally, we love how Audeze headphones pair with our amps. Their planar designs thrive on the high-current, Class-A power that Burson gear delivers.

Product Strengths

  • Excellent imaging prowess
  • A pure sounding unit with a tonality that is a bit on the warm side
  • Extremely well built with a full aluminum frame
  • Drives all different types of headphones with ease

Product Considerations

  • The power button and mode shift button feel a bit loose

  • Unfortunately, outputs cannot be switched, or the unit turned off, with the remote control

Comparisons (according to reviewers)

  • Vs Topping DX7 Pro: The Topping is ultra clear and has less body from top to bottom, it's a more neutral presentation compared to that of the bigger, more powerful sounding unit
  • Vs Chord Hugo 2: Sounds more natural—more analogue

Takeaway: The Burson Conductor 3 Performance/3X/3XP is an integrated component system that's great for listening to music and works well with many different headphones. It has excellent imaging and provides a fun listening experience.

Reviews

The Bluesound POWERNODE is the HiFi amp reinvented for the streaming age, combining audiophile-grade componentry and multi-room music capabilities to create an intuitive “just add speakers” hi-res sound system for modern music lovers. The compact minimalist exterior disguises 2 x 80 watts of award-winning HiFi amplification, a premium hi-res DAC design, and access to all the music ever recorded with a tap in our BluOS Controller app for smart devices and laptops.

Bluesound is one of the best entry-level amps if you're looking to dip your toes into hifi. Reviewers love it for what it offers at the price—solid dynamics and tight bass, which is exactly what you expect from good Class D. It’s the go-to pick for people new to hifi since it gives you about 75% of the high-end experience without needing a ton of power. It’s perfect for smaller setups where you want good sound without going all-in on expensive gear.

  • Connectivity options are through 3.5mm headphone-type connectors, shared with mini-TosLink connections

Product Considerations

  • Tough competition from other streaming amplifiers
  • No way to send data out to an external DAC
  • The Powernode was occasionally hard on transients and dynamic bursts
  • There is no included remote

Comparisons (according to reviewers)

  • The Marantz has a wider-scale, roomier soundstage and greater subtlety

Takeaway: The Bluesound Powernode is a superb streaming amplifier that is better than ever, offering excellent sonic talent and a well-rounded feature set. It provides a convenient and high-quality music experience for anyone looking to simplify their home audio setup.

Burson
Funk

/
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.
Check Amazon
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.

Our Summary

Product Strengths

  • Detailed and expansive presentation, offering a sonic upgrade to phones, especially when portability is a priority
  • Versatile, with both wired and wireless connectivity options, including balanced and unbalanced headphone outputs
  • Impressively small size and lightweight design, making it pocket-friendly and convenient for on-the-go use

  • Battery life estimation can be unreliable
  • No dedicated app for the device, limiting EQ and DSP options
  • Lacks a clip, making it less convenient for truly portable use

Comparisons (according to reviewers)

  • Compared to the Audiolab M-DAC Nano, the Go Blu offers a wider soundstage, better separation, and dynamic sensitivity, though the M-DAC Nano is fractionally punchier in the bass
  • Compared to the AudioQuest DragonFly Cobalt, the Go Blu is a wireless proposition, unlike the DragonFly Cobalt, which is a USB plug-in DAC
  • Compared to the FiiO Q3, the iFi GO blu highs are a bit too brilliant, but everything else sounded quite impressive
  • Compared to the NuPrime Hi-mDAC, the iFi GO Blu mids sound a lot like it, even if voices are slightly less natural
  • Compared to the Hidizs S9 Pro and Aune BU2, the GO Blu provides a relaxed sound and has better build and functionality compared to the Hidizs S9 Pro, but is better when using bluetooth compared to Aune BU2, however when competing on wired terms, the Aune is clearer

Takeaway: The iFi GO blu is a tiny but mighty device that delivers impressive sound and versatility—improving the wireless music experience. It is easy to use and has some cool features, making it a good pick for anyone looking for a portable upgrade for their headphones.
