I've found the Tesla tubes to be more musical than the Ruby EL34.But you really can't tell if they're not broken in enough.♫
Ruby el34s sound flat?
I just put a new quad of Ruby EL34s in my Quicksilver Mid Monos. The highs are limited, the sound stage is smaller and it just sounds veiled. Is this just a bad choice for this amp or do they just need to "break in"? Previously I had Teslas. I am using Gallo 3.1's
