Don't know whether you have made a move yet but here's my experience. I've have 3.6's for about a month, drive em with a Classe 200 and using right now Kimber 8TC. I'm waiting on my MIT to be converted from bi to single wire, but the 8TC does a superb job. I've also got cj tubes in the preamp. I've got plenty of power, no harshness, not bright, smooth and ultra clear. I just had Clapton "24 nights" and SRV "Couldn't change the weather" cranked and I've never heard either better. Acoustic guitar is great as well as driving bass/rock/blues. Good luck in your decision.
