what's the point?

Mission #1 should always be to avoid clipping at all costs. CLipping is public enemy #1 when it comes to good sound.

Most tube and many Class D amps soft clip which alone gives them a heads up on the competition. Soft clipping is much easier to digest than hard clipping which is the weak spot for many SS amps.

With clipping out of the picture most good quality amps should at least sound good but even then no two things are ever exactly the same. 

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.
