I was always a vinyl guy and purchased a SMSL SU-9 DAC as my entry into the world of DAC’s to replace the built in DAC on my Bluesound Node being It just didn’t sound that great. The SU-9 was surprisingly pretty good sounding but was not warm enough for me. Last year, I attended Capitol AudioFest stopping by the Black Ice Room and listened to their Black Ice Glass FX Tube DAC and liked it so much as soon as I got home I ordered one.… It utilizes a Burr Brown Chipset but has Tube Output so by rolling the tubes you can obtain a very nice sound. I replaced the stock tubes with 1960 NOS GE 5751 Black Plates and it sounds fantastic !…At times I have to force myself to turn off my system. I even demo’d it at one of our audiophile society's frankensystem events and the general consensus amongst the attendees was that the deck was very musical surprising many.
