Any plans to support a DT-1990 or HD-600s? I was wondering if the Beyer build may be better but I have no idea what drivers are in these; should I go with the AT build that you mentioned? (I'm mostly interested in gaming and media consumption, despite my cans) Also I'm not entirely certain why I'd want a subscription as opposed to a one time purchase, do ears change very much over time? (Not saying your pricing is unfair or anything, just curious.)
