Cpatbay,
Eq'euing the Krell HTS 7.1 is not as easy as in a Lexicon MC-12B.
You have to get some got test instrumentation and a handle of Acoustics. You basically measure it yourself, adjust parameters, measure, re-adjust.
We did on my cheaper Showcase (which I think runs the same software).And the difference from default setting was very obvious especially in low level detail.
Your dealer should be able to set this up for you.
