I recently purchased the Panasonic SCHT880, which contrary to 'What Hi Fi' is very sturdy build, good looking and plays with a punch with it's 1000w. The sub-woofer is very large though with 4 settings, which I play at no more than level 3. The only concern I have is when playing a DVD on the Panasonic player I experience a slight hummm from the sub-woofer, yet not when playing from the TV or my DVD recorder. I have been advised to "run the speakers in" where this should settle down eventually but I am concerned, has anyone else experienced this or has anyone else got any advise relevant to this slight hummm?
Thanks
