I understand that the HTR line is for the Big Box (Best Buy, Circuit City) distribution and the RX series is for the custom / enthusiast shops with slightly better features. I thoroughly compared the RX-V659 and HTR-5960 and found after reading all that I could that they were basically the same receiver as far as power, build quality, sound processing, etc. The only difference was that the RX-V659 had dedicated zone 2 controls on the front panel and the HTR-5960 does not. I ended up with the HTR model because it was cheaper online than the RX series.
