Magico S5 vs Wilson Alexia

Both speakers are "top grade" and both seem to have specific strengths and shortcomings, especially when considering the high cost involved vs long term satisfaction. So it remains to know why you chose these two manufacturers
instead of others that generally cost less to acquire. I can personally vouch for Sonus Faber, Von Schweikert, Eggleston, Joseph Audio, Aerial Acoustics, etc.
Evolution Acoustics are very musical as well from the comments many other listeners have made.
I haven't heard Magico's, but Wilsons require optimal acoustics and set-up
to perform at their best level. If you can find a used pair of Alexandrias they are really amazing, and i have only heard the 1st iteration of them.

Magico is only clinical if you have the wrong amp,preamp and cables!!

The S5 is voiced to be slightly warmer and more robust than the Q series. I have read that it is selling briskly for a +$25K speaker. I agree with Ebm. It depends greatly on upstream components. I have heard seven different Magico models and not one has sounded "clinical" to me.

I own the Mini2s. I happen to think that Magico speakers sound best with Class A SS electronics and analog sources.

Who says they are so different from each other? They are much the same in the most important audiophile parameter: Rave reviews in the mags. What else could matter?
