Hello Richmon,
I am not much into tube rolling anymore, but I seem to remember owners saying the RCA gray glass 6sn7 had a sweet midrange. As for the phono stage, IT IS WORLD CLASS! This is what Mick's preamps are known for. Get the best analog setup you can and you will be rewarded in the sound. I am using a VPI Aries 2 EXTended with the VPI JMW 12.5 arm and a ZYX Yatra cartridge. KILLER SOUND! I also have a Modded Sony SCD-1 SACD player. It can't hold a candle to my analog setup. Mick's phono stage will also handle the lowest moving coil cartridge you can find with no trouble. Mine is .24mv and I have tons of gain. You have a preamp that is worthy of the best associated equipment.
Have Fun!
