Down side of speaker swop from AZ to Tonian Labs ?

Wig,
How much you want to spend? I think Horning Aristoteles would be excellent for what you listen to.

I have the Horning Eufrodite Ellipse which are the next speaker up and love them. They ended my speaker search after over 40 years of being in this hobby.

When I had AZ Crescendos, I preferred McIntosh MC601 SS monos over McIntosh MC275 tube monos but it was close. I loved the Crescendos but I did get the fever to switch things around. I have never heard the Tonian Lab speakers so I can't compare.

Wig,
As I’ve mentioned to you in past correspondence at one time I was very interested in the Tonian Lab Classic 12.1 model. It used the legendary wide band 12 inch paper Phy-HP driver developed by the late Bernard Salabert. It was considered to be a superbly natural sounding driver by all accounts. It was a 2 way speaker with a ribbon tweeter, 97 db and 16 ohm impedance load.. After Salabert’s death I believe that Tonian Lab went with a different brand of driver. I’m certain whatever driver they decide to use they’ll still sound excellent given the designer’s talent.

Wig,
By the way I also had much interest in the Horning speakers. Very different design from the Tonian Lab but are quite highly regarded. 97 db sensitivity and flat 4 ohm load.3 way with multiple isobaric woofers.
