I have read many times that the M80s are very comparable to Paradigm's Studio 100s and sound very similar. I was just curious, how much of an upgrade/difference would one get from upgrading from M80s to Paradigm's Signature 8s? Is the upgrade really worth the $6000 extra? I know it would not be $6000 extra worth of speaker or omg blows M80 out of the water. I just want to hear from those who may have auditioned or maybe even owned S8s and to give their experience.

Speakers: Energy RC-70s, RC-LCR, RC-Rs and eD A2-300 x 2.
Receiver: Marantz 6006
