McIntosh MX119/134/135 pre/pro or Krell HTS 7.1

Keep the krell. Theo obviously has actually looked at the HTS7.1. The krell as an all analog pre-amp pass throu ability. If you use this for two channel, espcially with a balanced source and amp, you can't go wrong.

As far as the flexablity. apparently an 3 filter parametric eq for each speaker and a global parametrice eq all with multimple preset memories is either to complicated for theo or not enough.

As far as the sub thing, yeah krell calls that full range or full range plus sub

If you were to switch from the Krell to the Mac. I would have to say you would lose dynamics. The Krell has an very transparent and very imediate sound. what is on the disc is what you get. Some people don't like krell becuase of this, they want more of a "tone control". Or they want everything to have a similiar sound. You will get that with the MAC. The MAC is slighty fat sound. It won't be as dynamic, however the MAC has a wonderful way of making bad stuff sound good, but it also makes great stuff sound good.

As far a changing the amps. Why? What is it that you what to change sonically. Where is you system lacking? IYHO.

Kudo's on the DV-50. Absoultely the best universal on the market (other the the bigger esoteric's).

As far as the borrowing the FPB's - Willow groove is little bit of a hike for me. But, check with the guys at Soundex, I am sure they would love to let you try something in your home.
