I stream into an AN UK Dac-3 Signature from 1995 and through all tubes after that my sound is great.
Tubes make a digital service sing.
I have found that digital streaming needs a very good DAC -> Preamp -> Amp all tubes to come very close to an all analogue path. My amp and preamp are Audionote UK and my DAC is an ANK. I was wondering if others found the same thing. By the way ANK is really a good bang for your the buck
