Woo Audio WA7 Fireflies Headphone Amplifier/DAC in Silver
                                       - Superlative dac amp combo. using it on a daily basis with my iMac.
- Very good DAC. Can sate the power demands of almost any pair of headphones.
- This Amp/DAC combo work well with AKG K812. Highly recommend.
- The ESS Sabre DAC that Woo uses is a popular choice among portable music players and DACs. But this one have a spiky price.
- If you’re looking at an amp to seriously drive IEMs in this price range, it’s probably a better idea to go with something that can match IEM-level impedance with switchable gain.

                                       - Connect to my marantz cd6005 with wed performance coaxial cable sounds fantastic.
- Playing DSD files in my laptop it's excellent sound quality.
- Build-wise, the OLED display is nice and makes the unit look upscale.
- Very convenient to use, Hi-tech, DSD stream support, clear, juicy, detailed sound.
- The unit have some lack of bass. For that price it might do better.
Woo Audio WA7 Fireflies Headphone Amplifier/DAC in Silver
                                       - Greatest audio for gaming paired with Sennheiser HD 700s to fix trash audio in games!
- It uses vacuum tubes for its amplification and also has a built-in ESS Sabre DAC, so all you need is a USB cable to plug in any of yours devices.
- One thing that always impresses me about the WA7 is its total silence when not playing back any music.
- Clearly attention to detail was paid in getting the 1/8 and 1/4 ports matched in volume.
- XLR output would've been a nice inclusion for audiophiles.
