Hi Aleko,
I am not familiar with too many brands & amps.
I am using Dual Mono Block Tube Pre-Amp and Mon0-Block
Tube Power Amp ( P-P 300B ) and had them driving my
Mezzo Utopia for almost one year. Tube-rolling, ( of course only changing the 6SN7, 5U4 etc. not the WE 300B )
inter-connects/ power cables changing were all failure
to make it sound to satisfaction. So don't use Utopia
with 300B amps. (other tubes may be suitable more )
Because I like WE 300B so much, finally I had to change
to Parsifal from Utopia.
