You'll probably want to use XLRs for the extra gain. 6db is pretty nice.
I am about to make a deposit for a BHSE and would like to know what kind of connectors most BHSE owners use, RCA or XLR? What difference does is make?
PS. I'll be using a pair of Stax 007 and 009 with, as a source, a Bel Canto Dac 2.5
