I have a customer that has recently purchased a 5900 from me and he is unhappy because it is too noisy. its very difficult to tell in a store environment because it has a very high level of ambient noise. does anyone else out there own one and think its too noisy? i have personal experience with the 2200 (i have it in my home), and its dead silent at 6 ft away. i keep the screen blank on it most of the time and i forget to turn it off a lot of the time, i dont even know its on. he claims that at 15 feet away he can hear it during quiet passages in movies. is this common, or could it be a defect? thanks!
