I had wanted the obvious choice, the yam 1400. I can`t afford it now. I have to stay in the $500 range. Choices I have researched are htr5660 or sony strde995. I may be able to go to $600. Lookin for music mostly want to get to HT. Ability to add an amp would be big cause I like to feel my sound. Options would be greatly appreciated. Thanks.
