I agree, I have a Ref 507 and for HT and DVD-A, I really think it sounds very good, but of course I only paid $2500 for the unit new(yes $2500 for a 507). As for 2 channel it's not great but thats what my Pass Labs system is for. If your going to use this unit for AC3, DTS ect, and multi channel DVD's, then at the price there going for it's hard to beat.
