Selling a mint condition Ifi Pro iDSD DAC/amp. There is not a single blemish on the unit. This unit was upgraded to the 6n3p-DR gold pin tubes. I have tried several tubes include $150+ ones, and these Russian tubes sound the best. The improvement is very substantial. I can put the original GE tubes (will be included) back per buyer's request. All original accessories, cables, paper and box are included. I'm listing at the lowest price seen on classifieds because I got a deal on an all-in-one box for my new speaker set up, so I need to sell off my headphone setup quickly. I'm also selling my Soundaware P1 amp (see my signature). I used this combo to drive my Susvara for over 6 months. It sounds ridiculously good. If you want the combo, I can offer even heavier discount. Listing price includes shipping with insurance and shipping. Bay area headfiers may pick up locally.
