Placette should be on your radar screen, and it also addresses your availability for demo concern as they offer a 30-day money-back trial period so there's nothing to lose. If your system is still bright on top and thin down low with the Placette it's somewhere else in your system. You can see reviews on Soundstage! and Planet HiFi.
I've also heard very positive things about Atma Sphere preamps, but I'm not sure about the demo situation--they may also offer a 30-day thing.
