Hi,
I'm sorry - I never saw your PM until now. Have you made your decision yet?
I recommend a Denon 4300 or 4400 as good values with a separate amp for your Martin Logans. I'd keep an eye here, Audiogon, US Audiomart and eBay for a good used amp. If considering new, check with Steve at Sound N Video - he's extremely knowledgeable and has great deals for AV enthusiasts. I love my ATIs - they're incredible and bulletproof. Their new amps and their Signature Series are even better.
