Those NHTs are great speakers. It's a shame that they shut down operations not too long ago. Supposedly, it is only temporary, but there was no indication if/when they would return.
There is something to be said in terms of quality vs. quantity (loudness). Many times people tend to crank their music due to poor quality (speakers, receivers, crappy MP3s, etc.). The idea, I guess, is that they make up for the lack in quality with, simply, more. It's kinda like eating at a buffet (think Golden Corral, if they are in your area). The food usually isn't terrific, but people will make up for that by crushing relentlesly until they are satisfied. Those same people may not crush so heavily if they are at a nicer restaurant with better food. The same can be said for audio equipment. I don't have a lot of "stuff," but I chose to invest in audio equipment, because I really love music, and I appreciate listening to fine reproductions of quality tunes.
That, and concerts on Palladia are bad-a*s.
