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.
