thanks guys
seems the record with the most trouble was a slightly warped one. I went back and lowered the volume a little and haven't had the pumping effect. It's mostly very demanding passages - doesn't get overloaded on jazz like it does on some rock records
I have a ZYX Artisian outboard phono pre and will try that in one of the line imputs on the doshi - perhaps there is a roll off in the low freq end of the phono stage
it doesn't do this with cds
I'll touch base with Nic Doshi and get his comments on gain and low end frequency
I believe I do have that test record
thanks
Tom
