My current favorite pair within that price bracket is the HD 558/598. Imo, can't really go wrong, but ymmv.
Yeah you're right... Amazon reviews aren't always the best place for information, I was just suggesting it in case OP is skeptical. Op... if you don't want to read the Amazon reviews, just look at a couple of Howard Stern videos, "The King of all Media" only uses the best. Sony MDR-7506 is standard equipment, used by very successful long time professionals, in professional studios... around the world. Still don't think MDR-7506 is a great deal? Well then just search anywhere for info about these headphones, it is hard to find bad reviews about them.... most negative comments are from people who bought counterfeits. Anyways... good luck OP, hope you get a great set. Cya.
The headphone amp arrived today and I'm testing it out now. So far, my mind is totally blown. It really makes all the difference!
