Qinpu Q-2 Tube/Hybrid Headphone Amplifier
Will Ship To: Continental USA
2.5w/channel stereo tube/SS headphone amp w/ a GE 5670 tube. The amp originally came with a crappy 6n3 Chinese tube which sounded horrible. The GE tube is a 5670, I think, as all I can read on the tube is the GE, which is printed in green. The numbers are worn off but that's the US equivalent tube for the 6n3 and it looks the same as the the GE 5670 images I've seen on the internet. In any event, the GE tube sounds much better than the 6n3. The amp is in excellent cosmetic condition and it works perfectly. The amp is cute as a button and drives my AKG Q-701s, Audio Technica ATH-AD700s, and Grado SR 125s well. There's a good review of this amp by Skylab here on Head-Fi and great pictures.
$80 plus actual shipping. I will accept PayPal only. I will only ship in the US.
