Re: Vacuum Tube Logic - VTL TT-25 Amplifier (Tube)

Hi Vinylly,

Great review. I have a few questions for you though:

1) When did you get these? You do know that there were quite a lot of changes from the former Tiny Triodes (made in 92?) to the newer Limited Edition ones, right? (i'll attach the email from Bea Lam to me below)

2) What is the sensitivity of your speakers? I am using my TT-25's with a FT Audio LW-1 passive pre (and before with the McCormack MLD), and I rarely turn it up beyond 9 oclock. I do really like the AIM3a, but I worried about pairing it with my system with its notoriously-high gain -- glad to hear that it works well with your system.

3) Have you tried rolling the 12AT7's? With what, and to what effect?

Thanks!
Keith
