I have a Sony home cinema system, with an class D S-Master Amplifier, which I've owned for around 4-5 years now. Basically what I want to know is, does playing music/films at a very loud volume for long durations throughout the life of the system eventually degrade the sound quality, or damage the speakers or amplifier so that the sound is quieter. Taking into account that obviously years of loud music has made my hearing a little worse! The system has cut out a few times as a "protection" during long hours of loud music at parties etc. Any info would be good! Thanks
