Vhiner,
"I am not casting aspersions on anyone's advice here, but I stick by my earlier statement that system synergy can be elusive."
If you were referring to my post, you may have gotten the wrong meaning. I was agreeing with you. I just took your idea and went a little further with it. The dark art applies when you are building a system in your head. Things like reviews and comments on threads like this give one ideas as to what they want to do. The problem is verification occurs, more often than not, after the purchase, and not before. The darkness.
Your 2nd post is as good advice as can be given. If the system sounds good, just be careful. Its far easier to make a good system sound bad than a good system sound better.
OP,
The Krell/ML combo is a good sounding, neutral and powerful base to build a system on. They should sound very good with a very wide range of speakers and sources.
