Just an update for those who pitched in with info or followed this thread: I ended up going with the Bel Canto Pre3 and it sounds fantastic in my system. I'm listening as I type this, as a matter of fact...Very happy with it.
It's a significant, not-at-all subtle upgrade in SQ from my Parasound P/LD-1100, more so than I expected to be honest. The old pre was clearly holding my new speakers back -- not anymore! They now sound every bit as good as they did when I first heard them demo-ing in the audio store.
Lots of good preamps were suggested by forum members, so hopefully this thread is helpful to others in the future. Thanks!
Next up...new amp :)
