@dsper have you decided on the Carerra or Carbon ?
I ask because I've used some of the same Scanspeak drivers in a few speakers I built, and upgraded, similar to the Fritz Carbon 7 SE MK 2. Warm, full body, nice.

The AVA SET 120 control amp and this speaker could be a nice combination for you. I've studied Frank's amps quite a bit, his design, mosfets he uses, and this particular amplifier . You might ask Fritz about this again too, I think he recommended a similar combo. Return policy options on both make it low risk and possibly fun to try fwtw. I like this idea. Might be a nice little system, best of luck.
