Can somebody please try to explain to me in non technical human language what is the difference in sound quality in regards to wattage. Assume hypothetically, I'm playing the Who on a classic rock remastered CD on the same DVD player at the same listening volume on a 200 watts receiver speaker system and a 600 watts receiver speaker system in a 20 foot (average sized) living room. For clarification, the listening volume is the same (say it was set on 5 for the 200 watt system and 2 on the 600 watt system). What will I actually hear to my ear differently-anything or will the difference in sound quality be negligible. Will the drums, vocals, guitar, or bass sound different. Will there be any more seperation, clarity, richness or warmth in the sound. I am not interested in what the difference would be hearing classical music or how somewthing is numerically different. I just want to know what the difference will be in what I'm actually hearing. Appreciate any response. Why this doesn't seem to be spelled out on any web page is beyond me.
