I'll also join in to favor the HTS 7.1. It beat many stand alone pres I had over to demo. It doesn't seem to be a popular piece around here, but my experience with it has been extremely favorable, quite contrary to many who "blast" Krell. It is the one piece I've had for the longest time. I've used it with a variety of amps and for 2-channel, M-channel, and movies too.
Krell HTS 7.1 vs. Showcase
I'm looking to combine my HT and stereo due to space... so I need a pre/pro that can really play music. I already have a Krell amp that is fantastic, so the natural choice would be a Krell pre/pro. The question is... is there really a difference between the two? Videoswitching is not important at all.. never use it.
