Buy this if...

  • You want a striking, sculptural desktop centerpiece as much as an amp
  • You value a dead-silent noise floor and smooth tube-flavored sound with headphones like HD650, LCD-X or Arya
  • You're willing to pair it with an external DAC and possibly roll tubes or cables

What users love

Skip this if...

  • You need the amp to fully drive harder loads like the HD600/HD800 at high volume on single-ended output
  • You expect the built-in DAC to compete with dedicated standalone DACs
  • You want tube rolling to produce a dramatic, guaranteed sonic change

Who wins on what

Ranked by what users actually praise

Overall Impression

The design is the star of the show for most owners. Commenters repeatedly single out the WA7 Fireflies for its looks, calling it gorgeous, museum-worthy, and beautifully finished, with the visible glowing tube and premium touches like the Samtec high-retention USB port drawing praise. Several say the aesthetics alone justify the purchase, and one reviewer's setup with purple LEDs and chrome finishes was singled out as breathtaking. For some buyers, form factor and the lack of a bulky remote were explicitly cited as reasons to buy.

Sound is smooth and quiet, but the built-in DAC divides opinion. Owners describe a dead-silent background, solid soundstage, and a tube-added sparkle that pairs well with headphones like the Arya, LCD-X, HD650 and T90. Several listeners say it tames bright headphones like the HD800S while adding bass authority. However, multiple commenters flag the internal DAC as mediocre compared to dedicated DACs, and one long-term mk2 owner called the overall sound clinical and unmoved by tube rolling, questioning the price-to-performance ratio.

Power output and driving harder headphones is a recurring debate. Some commenters insist 1500mW is plenty for most headphones, while others argue it cannot fully drive demanding loads like the HD600 or HD800 to their potential on single-ended output, urging use of the high-gain switch for such headphones. This ties into broader upgrade discussion: NOS tube rolling and better power cables reportedly elevate the sound for some owners, while missing remote and cables are explained as deliberate choices tied to global shipping compatibility and buyer preference.
