Oh no, oldskoolboarder! When my wife (or any other family member) is already in bed, I would never set the volume above -25dB or so. That's what I meant by "seriouly watch" above.

Yes, -5dB is VERY loud. But it is not THAT loud so it permanently injures your ears... Remember, at your local cinema theater, you are listening to the soundtrack at 0dB reference by definition.
