I've listened to XVX for a couple of hours (driven by Gryphon Memphisto monos), listened to CH M1.1 driving XLF many times, but I've not auditioned Alexx V. It's hard for me to imagine M10 not able to drive either Alexx V and XVX adequately. If one doesn't like the combo that's one thing.

What am I missing here? Who said the M10's can't drive the XVX? Certainly not Harley who apparently thinks they do a good job. I think its worth repeating... the Alexx V is NOT the XVX. If you look at their impedance curves, they do in fact differ a bit. How this manifests in "driveability" of each with M10's, I have no idea.

Ahh I mis-remembered what speakers you have, Marty. Both models have X's and V's and my tiny brain didn't distinguish. Apologies.

I had the opportunity to have a private 10 Series listening session in SoCal today. I had read a few of the comments posted on this thread so I went in particularly focused on the bass performance. Maybe its because I had the room to myself without distraction, but I was absolutely blown away. Not only was there more than enough bass, it was texturally exquisite. The depth and dimension of the system was remarkable. And, we were barely making the amplifiers sweat. For that reason, I cannot imagine that the M10 couldn’t drive nearly any speaker if properly set up.

On another thread I wrote that the best amplifier/speaker combo I had ever heard was in Mike Lavigne’s listening room. This combination certainly gives Mike’s a run for the money!

What was the speaker you heard the CH with?

Yes, the Stenheim Ultime 2. I was amazed at how effortlessly the amps drove the speakers.

Not just CH..Everyone!! How do we make the "uberamp swap club" happen??
What is the entry fee for the Amp Swinger Club? :D

Do you know what the setting for the Feedback was?
Maybe it was relatively high Feedback which might be good for the Bass but the high Feedback could also prevent the Mids and Treble from sounding even (much) better.
Marty's point is that if he sets the Feedback for best Mid and Treble, the Bass is not satisfactory for him and vice versa

Yes- and his “rooms” can pose a challenge, yet the sound was exceptional. So, how good could it sound in a “real” room?!

Why are his rooms challenged?

I am willing to get involved however what's the yearly membership fee? Rules/ Obligations? It has to work financially for everyone ..
They do this with boats here in Florida BTW :)

The more significant measurement is EPDR, calculated from the impedance for both the XVX and the Alexx V in the Stereophile reviews.
Thank you for bringing EPDR (Equivalent Peak Dissipation Resistance) to our attention. I went to the Stereophile article that describes this in great detail. I'm surprised the issue hasn't been raised previously (probably because most of us have forgotten or didn't appreciate or understand its importance). This is the first thing I've read that provides a a genuinely solid scientific basis for understanding why some amps may not be a good match for certain speakers. Kudos and thanks to Francisco for bringing this to our attention.

There's an old saying "If you can fly it, float it, or f*** it, it's better to rent than buy."
The first thing we need for the uberamp swap club, is a word for what we do that start's with the letter "F"!!
(Sorry for being OT- might this subject might have legs as a separate thread?)

Marty, how about Feel, Fear, or Flaunt it?
