No, using the Karan monos on the bass panel and my own design (AB amp) on the tweeters. I have tried the NAT Symbiosis New on the tweeter position and preferred the matching with this AB amp. With that said, I will likely have a class A design (Pass Labs?) on the MRT as it's not very demanding in terms of power, given the high pass frequency.
First Watt SIT 3 would probably work for the midrange, but for those who like oomph, the newest SIT 5 monos have more juice with the massive SIT and MOSFET current contributor.
Don't know the efficiency of the Clarysis mid or impedance, but I run my Wisdom 75 inch mids to good effect with as little as 2-3 watts (crossover 300)@ 6 ohm impedance, but I imagine Clarysis would like some extra current.
One of these days I’ll do a longer write up on this speaker and learning more about it through designing this crossover. I’ve actually learned quite a bit — which is I guess the most rewarding aspect of this hobby (for me at least).
