Best place on the web for advice, information and endless bickering about almost any aspect of anything remotely related to headphones is www.head-fi.org.

Just copy your post, minus the line "Sorry if this is the wrong place to post...", in the "Headphone" section of the "Equipment Category Forums" and I assure you will not only get the answer but also be told how much better other Stax headphones are, how to upgrade the cable, the amp (along with which tubes to use, if it's a tube amp), the ear pads, etc. Well worth a visit.
