Hi, I have just bought the Strdb 940 from Sony. And when i turn up the volume over 1 quarter(9 o'clock) it starts to hiss. Most noticebly from my center speaker and my fronts. Even when only the amp is on.(other components are OFF)i still hear the hiss. turning the power up till 12 o'clock makes it Really noticeble. I can't believe this amp has been so highly rated in all these magazines. Are the people deaf that tested it? or did they only test it at a low or very loud volume. (in Both cases you won't notice the Hiss) Anyway for me this problem is just Not acceptable. Right now the dialogue from my TV set is better/clearer than using my surround set and it's center speaker. It seems that it's not only the 940 that has this problem...but also older models like the 930/925 or the 830. So i am curious if other owners of sony amps has this same problem.(Is it a common problem with Sony Amps) And what that have done to fix it or even if this is fixable.(Has sony acknowledge this problem, what have they done to fix it?) Avoiding using DSP modes or Bassboost is NOT an acceptable solution/fix. Thanks a lot and i look forward to your feedback. DT PS I just saw the movie "The River Wild" with Meryll streep. That's exactly the effect that the Hiss has. It seems that all the movies you see has as a background a running river. To say the least very irritating.
