I had the same issue when I had 3.5Rs. I tried biamping, then active XO, using a Parasound A23 on the ribbons helped a lot, but it stayed really hot even at idle. I think if my current amp (EVS 1200) was available then, I MIGHT still own them . Aas, wile active XO is the way to go, balanced XOs are $$$$ and cheap ones are crap (I blew up 4 of them @ $200/. No way to know, but people on another forum are using current class Ds and seem quite happy

Fritz... just a great guy. Talked to him a few times and have had two of his designs—great speakers. The best way I could describe his series crossover is that it sound like point source coaxial driver, but so smooth. His original Carbon 7 had such a dark and euphoric sound but with massive imaging and texture. Unfortunately I sold for two reasons, they overloaded my small room and had to pull double duty for HT. In a larger designated listening room these would keep me happy : ). I was saving up for his Carreras but after talking to him a month ago he seems to be very excited about a new version of his Carbon 7 speakers that utilize the new Carbon woofer (faster) but also a different Scan Speak tweeter (limeted addition). What I gather from chatting with him is that he may even like the sound of this less expensive tweeter in the series crossover than the previous gen 2 Carbon 7 that utilized the air Circ tweeter. He has it advertised on audiogon but not his website.

Spatial is releasing their M5 Sapphire speaker ($3K) that I'd be very tempted to try.
