Let's not forget he is working with a Sony amp and they are notorious for ratings that are well under actual real world requirements. It may have the 100watts on one channel with 1/8th watt on the others as required, but if it needs to use 50% on both fronts it most likely is only giving him 50W/ch or less if other speaker requirements are high as well, so it could very well still be an under power issue; not to say that a weak input signal couldn't be the problem or help alot as well. I noticed a huge increase in over all sound quality/loudness going from a Sony dvd player(middle of the line at the time) to my current Samsung(top of the line at the time). I am sure the output levels on that Sony were about half of what the Samsung puts out.
