Pre-Amp Tube Opinions

[herbert001442]

Hey folks

I just recently revalved my Herbie with Winged C EL34 Svetlana's from Rubys and also replaced the TAD Preamp tubes i had in all positions with Harma 7025 Cryo ECC83's

Has anyone else tried this configuration? Just looking for your opinions on the sound

Cheers
