I haven’t spent a ton of money on DAC’s. So I know there’s really good ones above my price point. But I bought a Black Ice tube DAC at $900. Replaced the power chord with a Pine Tree iso-braid power cable, and the game changer for me was purchasing 2 NOS Amperex Bugle Boys (12ax7) for the output tubes. I’ve got the magic of tubes along with many other superlatives. I’m good for now!
