Missioncoonery, yes I agree, but think about tube rolling a little bit. I've got a little single-ended, Class A headphone amp by Woo Audio. It's wonderful, BUT I can change it dramatically by simply changing the recifier tube, replacing my $10 Russion tube with a 1950s metal base Holland GZ34tube that ranges in cost between $300 and $700, IF you can find it.
The improvement is HUGE in my headphone amp example and it's still not as good as my Rowland SS. I don't see the "advantage" of tube rolling. You've got a high likelyhood of worsening your tone, not improving it. Why would you want to introduce such a big variable into your system??
It's one thing to roll tubes on my guitar amp, where the idea IS to color the sound, but on my high fidelity two-channel system I only want tubes that are "accurate" and "transparent", yet such a thing is hard to define, much less find.
