If you are into NOS DACs Abbas is a name you should KNOW, I wont WAX on. The DAC is 100% Functional sounds sublime. It uses 4 tubes, 6x5 Rectifier, E180F, CV4025, & 5687 (a good set of vintage tubes are installed with approx 500 hours on them. I have spare tubes that can be discussed but are NOT included in the price

I would prefer to trade for: Audio GD Master 7 Series (The units that use multiple 1704 chips), Audial s series DACs, Lampizator Gen 4+ dacs
