Hey, John
I have heard a great deal about Bob
but I personally don't know his work.
Presently, he is working on my amps so I
should have more to say about his mods later (1or2 weeks).
If he is as good as I think he is, I will try to talk to Bob about my new phono-stage (Consonance Reference 40 -- MM, MC, tube ractif. EZ80 and 2, 12AX7 & Amorphous MC step-up transformer) and what can possibly bring the best out of it. I know there is a room for improvement ( I have seen the guts).
