what's the point?

with Class AB amps too much power is never too much.  I have found that 300wpc in my living room is just right for my speakers and what I listen to. 

Why are there posts like this? The “no difference in sound” group is over at ANA where all the other deaf people reside

Seconds on Crown. I absolutely LOVE mine; great value for the cash and rock solid performance.  Mine drives 4 four ohm monitors with great ease at 450 RMS WPC. Have had at least 15 power amplifiers since I was in my teens. Wasted a lot money; should have bought one from Crown to start. 

Roger Modjeski argued that since most amps will occasionally be driven into clipping, how an amp behaves when it does so is an important factor in how good an amp it is. A reasonably good tube amp clips more "gracefully" than do many solid state amps.

bdp24,
Your classic straw man argument above simply says: This controversy over amplifer differences is just as beneath consideration as the ones you name...but why?  Can’t one carefully set up well designed speakers, tastefully match choices of interconnects and speaker wires, use good judgement on room treatments to optimize everything possible...and then drop in a Crown amp...and get very satisfying results?  I think that’s the OP’s point and Bob’s.
