Near mint condition USB 24/192 DAC uses a 6922 tube. Very warm, natural sounding dac that can also use many other drop in replacement tube types for rolling(6dj8, e88cc,ecc88, 7308 for ex.). Comes with the stock Electro Harmonics 6922 which has much life left on it. I used this sparingly in my office. I have original box(which looks used from shipping BTW). I cannot put my hands on the manual but will keep looking.
Feel free to ask questions.
Sales to continental US only. No fee for Paypal.
Thanks for looking. Will add pics later.
