I'm currently looking to upgrade my receiver. My primary use is home theater/TV, probably 80%-90%. I want something that I won't have to upgrade soon, so I'm looking at 7.1 compatiable receviers. One of my main concerns is noise level, as my current receiver definitely is not quiet. I've listened to the H/K, Yamaha and Onkyo (797 and 898) receivers. I'm also looking at the Pioneer 45TX but have not been able to demo it and at the upcoming Denon 3803. Yamaha doesn't support 7.1 but sounds great. H/K's also sounds great with not a hint of noise at any volume but lacks some of the features of the other brands. The Onkyo 797 is noisy but has great home theater performance and in that case seemed to sound better than the 898 (although the 898 wasn't noisy). The 797 seemed to be more forceful sounding in movies with more volume and detail in the rear channels compared to the H/K and 898. If I went the Yamaha route do you think that I would really be missing out on that extra rear channel? Am I going to need to upgrade again in a year or two? Has anyone listened to the mew Onkyo receivers and do they exhibit the same noise levels? In regards to the Pioneer is it noisy, exhibit any hissing etc? Also how does it sound compared to the above units in home theater mode? Any help or advice would be appreciated.
