Boy,this should be interesting! I haven't pulled the trigger as of yet on a Supratek preamp and have been fantasizing and reading about ownership.Presently, my amp has volume controls and my system sounds stellar to me with my digital source directly connected.I was also smitten by the "jaw meet floor preamp".....Dodd battery powered unit but the buzz from what I am reading so far hasn't met the hype or I could be wrong.I haven't heard one and don't know anyone who has one locally but I will keep researching and hoping it's a winner.
