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 ?

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.
