Wow that is many tubes. So many to know what is best in sound. The preamp you have is very good.
I would not have gone hat route but as I am old I remember when I did. Heat in the winter for sure. Tubes somewhere always makes music over sound. Ok but I would think you would need fast tubes in your dac as it seems you have enough tube sounds
Hi Al, current GG is PX4 and KR 274B, I suppose they're fast enough. LOL..perhaps I should try the Tak 274B. Maybe..just maybe, I can get what I have been missing.
