I see. Does that also mean that all of your volume control is done from the tube preamp? Or can you still use the remote for your C370? Also, you now have me interested in those tube kits. How difficult are they to put together and how expensive would one with TWO outs be? Do you have a link you can point me to? Oh and yes, I've thought about the C270 option, but I don't know if I want to give up the luxury of a remote control. I guess we're all spoiled by those things. Sorry for all the questions, but you really sparked my interest in a tube preamp.
