Hi Folks.I Finally have my system up and running. It sounds great, but I seem to have a little problem. I have an Oppo 105 and I'm running Pandora etc and an Esoteric K-03 fo CD's etc. The Oppo has A LOT more "punch" in the bottom end. The difference is, I'm using RCA on the Oppo and XLR on the Esoteric. I've actually read the preamps owner's manual and I'm aware that you can adjust the XLR internally +6db. The Esoteric has that funtion internally which I've adjusted. Thoughts????
