I just realized that my E9 only has RCA out. WTH? The only way into the E9 is a generic one-port line-in or USB?
Grrr.... My E9 is now useless with any other DAC - especially the one I just bought that has RCA interconnect line-outs (HRT MSII+).
Guess I'm in the market for a good SS amp that has RCA inputs.
Dude, RCA to 3.5mm cable to the line in.... THAT'S IT. It's the SAME quality.
