I have recently auditioned all on your list plus the NAD742. They were all runners up to the Rotel and NAD with the NAD being the warmest. HK came in third with the other Japanese makers sounding very bright. If you are looking for warmth for under B&K prices, I would say the NAD. I ended up with a HK AVR330 just because it was a deal I couldnt refuse. I heard the Arcam AVR200 has a similar sound as the NAD.
