tube DAC noise

....recently tried the Black Ice DAC. Really enjoyed the sound only the tube noise was noticeable on quiet passages. Do all tube dacs have this ?

I have all tube equipment on my main system and four headphone amps..; no noise... none. Total of nine components. One can get a noisy tube occasionally. Sorry don’t know anything about black ice.

It was someplace in the rca jacks...checked them and they looked ok...I promptly sold it. Waiting for my border patrol to arrive.

Upscale and Andy at Vintage Tube noise test every tube sold. Brent Jessee charges $10. There's no noise or tube hiss from my Audio Note DAC.
