I own a Cary SLI80HS, i really enjoy it. Built like a tank. I know it's not a 300b nor is it class A, but to me does everything right. I would not hesitate buying a Cary.
As for the Triode Labs, I've listened to a couple of their 300b amps. Definitely some of the best sound I've ever heard.
If I hadn't found a good deal on my new to me Luxman 550AXII, I would be in the same boat as you. It would be between the Cary CAD300SEI and the Triode Labs (If I could come up with the extra cash).
Cary Direct has the 300 SEI at a reduced cost of $4,871.00
