I am running an SS pre into one of Bob's ST-70's with EL-34's. My speakers are JBL 4311's which are pretty agressive.
Although I like what I am hearing.....The music sounds very alive but at times the sound sounds harsh and over driven. I am wondering if I have to much gain between my pre and the dynaco.
My pre puts out 50 db from the phonostage for MM than I have a step up for MC which bumps it up another 23 db for MC.
I also have the high gain board. Now the last thing I want to point out is that the pre does have an attenuated output for driving more effecient amplifiers.....which I am using so maybe its not a gain issue?????
When I get a tube pre from Roy I am going to have the low gain board installed....
