It's a Yamaha RXV730 Dolby Digital 6.1 w/75 watts per channel. Now he's got one that is similar and I heard it, the imaging is incredible!!! Much better than my old piece of junk Kenwood 5.1. What I want is a good 6.1 receiver for $600 or under. The one above is only $400, but I think it's because it is an older model. The next model up is the Yamaha RXV740 and it is $600. He said that the $400 model has everything I need and more. What do you think? If there is a BETTER receiver you can recommend for $600 or under, I am open to suggestions!! Please help! Just so you know, I have the Boston Acoustics VR Reference floorstanding towers, large VR Reference center, and Bi/Dipole VR Reference rears (about two years old). Thanks so much for any/all help you can provide! I know nothing about what is out and what is good or bad. Thanks again!
