MB, the only place I have heard multichannel done right is in my system. That's not bragging, because it's quite easy to do, and I'll tell you how.
Begin with a good two channel system, like ESL's. Double the Left and Right speakers, mounting them at an angle dictated by your room. Right angles are a good place to start. Right away one hears something like an MBL with clean, fast bass.
Now add two more ESL's in the back, for surround. Best is to blend the Right and Left signals, but that's not absolutely necessary. What is necessary is a volume control. Set the volume control to the highest level which cannot be discerned in the listening position. That provides the concert hall ambiance without the source confusion.
