Clayton S100s/M200s and Essence Sapphire

I'm sure this is a long shot, but I'm wondering if anyone has heard both the Clayton amps and Dale Pitcher's older Essence line, particularly the Sapphire. I've had the opportunity to listen to the Sapphire for an extended period and find it outstanding, the best solid state amp I've ever heard by a long way, and in fact better than any tube amp I've heard overall. But I have also heard wonderful things about Clayton, things that suggest I might like them quite a lot too. So, for the rare and lucky person who has heard both, and enough times to form a reasonably informed opinion, how did you think they compared?
Never heard teh Essence. I've owned the M-200's and now the M-300's. They're great amps!!!
