I agree often old school has somewhat of a poor sound, I'm not concerned though until I hear panning issues. That is the most annoying thing ever. It's all in the how revealing the headphones are, I didn't notice so many problems with my old stuff, but when something is well produced it sounds oh so amazing.
Also Porta Pro's are the best on ear headphones for the price. It's like the national headphone over here, you see so many use them.
Those things are very expensive thou
