I know I'm in no position to answer this, and I think few here are. Brainwater is the only member I can think of off the top of my head that may be able to answer. I love his gazebo-jacuzzi system. He has $70,000 speakers, $26,000 speakers, $7,000 speakers and more. I would think that the answer would be the same as the answer you would get if you took 1 (0) off the end of all your numbers. For instance, many here would be able to tell you what difference a $8000 speaker makes over a $1500 speaker. I feel the answer would sound similar, just the numbers change.
Cheers,
John
