For fun, do you have any 12au7's around? The PH-7 uses 12ax7's, correct? Try the lower gain tube? If not 12ax7's, which tube does it use?
CONUNDRUM
I'm fairly new to vinyl. In my haste to put together a fairly nice front end, I have created a mis-match between my cart, phono stage and my linestage. I have a Clearaudio Maestro cart feeding a ARC PH-7 feeding an Aesthetix Calypso. The PH-7 is over driving the Caypso with no way to reduce the output without sacrificing quality of sound. (attentuators don't work. In dropping the output, they also compromise the signal quality)) I can go to a low output MC coil cart, or change one of my preamps. I'm looking for a WARM sound with all the usual qualities one would want in a good sounding system. The MC cart seems like the way to go, but the $$ keeps piling up as it so often does in this hobby. Suggestions please.
