Hi Epoy
Ever since I got the H 80 from you nine months ago, I have not used my tube system. Last night, I compared the SQ of the H80 versus my tube preamp and tube amp. Sources used were CDP and Spotify running thru Bluesound Node. An external DAC was used for both sources.
IMHO, very little discernible SQ difference between the H80 and the tube system.
So for now, tube system in hibernation and may come back to life during cold nights for the warmth of tubes.
