You may want to try Sound Application's CFX. I have recently inserted one into my system with great reticence, mind you. I also had concerns of limitations brought about by "conditioning", but this unit,still in break-in period (reported to need weeks and weeks of break-in), has offered some noticeable and welcomed changes. The most obvious is the blackness in the sounstage. Initially, this character sounded less musical- more hi-fi-ish. Fortunately, as the piece settles, the music amidst the soundstage widens and fills out. The frequency extension has had no deleterious affect even with the amps plugged into the CFX.
