best speaker?

My system upgrade is going to include getting rid of my 331 and replacing it with a 23.5 or 436 monoblocks and the Revel studio.I am not able to listen to a 23.5 versus the 436 and hence the importance of this forum in giving me a sense of the 23.5/20.6 ML.

The Thiel 36 image beautifully,however I listen to a lot of trio jazz eg Jarret and find them harsh in the high frequency and would like a more open and liquid midrange.

What about other amps viz Plinius/Audio research/Simaudio with the revel studio versus the 23.5?

Thanx guys.

I am curious in the difference in quality/characteristics of the 336 and 23.5.Some say the 23.5 was the best amp mark levinson built-is it better the 33H?All of this in reference to good quality speakers.Any thoughts on Thiel CS6/7.2?
