I am selling my Audio-GD Sparrow type A DAC/headphone amp because I have upgraded in the Audio-GD line. This is the more desirable Type A with the better caps and the Wolfson DAC (see the Audio-GD website for more detailed information). It is in excellent condition with only a small scratch on the top as shown in the pictures. The USA dealer that sourced it also scratched the serial # on the bottom of the unit. I am the second owner. The original price was $270 (invoice enclosed in the package). I will throw in a Volex heavy guage power cord in place of the standard one. Free shipping and paypal in the USA. It does have USB input thats hard to make out in the photos.

The electrolyte capacitors are custom ordered from NOVER (a UK brand), exact matched transistors, an ALPS volume pot . RCA sockets are custom ordered and 24k gold plated. All transistors are Toshiba and Hitachi.All aluminum chassis (Black).
The PCB employs 2MM double copper/stringy board, 70uM copper.
20 Watt custom transformer, with a wide input voltage of 100-130V or 200-260V.

Sound Characteristics: "Neutral but smoothness sounding ,it doesn't sound skeletal or digital (or metallic). There's meat aplenty on them bones . It's a sigma-delta DAC chip implementation without the dryness, neutrality without the emotional disconnection" - John Darko
