Snook2's idea is good, but it's not the route I preferred. To each his own. I had an Opus 21 CDP that could run direct. I tried both variations and preferred using a preamp to running direct. The direct route was more transparent, but including the preamp made it more dynamic, musical and enjoyable. There have been a number of discussions on this board on using or not using a preamp.
The C2200 is a great preamp. I have not heard a Supratek. If you have access to it Hifi+ recently reviewed the C2200 and loved it. I actually use some of the features on the C2200, like the mono switch for older recordings.
