Ok.. I have Polk Monitor 50's and 40s for the rear and am buying a CS1 for a center channel, and the JBL S120PII sub.. Right now I have a Harman/kardon AVR130 - I like it but compared it to the Onkyos in C-city and they sound much better.. I work at bestbuy so I get a discount on the Yamaha HTR models. So basiclly I waslooking at the Onkyo TX-SR602, Yamaha RX-V650, and the Yamaha HTR-5760 If there are any other recievers out there that I can purchase in the 400-700 dollar range let me know but I'd like to stick with the best of these 3.
