Selling because they're a bit warmer sounding than the universal model and a little too warm for my tastes. I prefer the universal model for sound. 64's description of the A12t is warm and balanced and I'd say that's and accurate way to describe them. I have had them for only a couple weeks so they're essentially brand new. They shipped on Nov 12th and I got them a few days after that. Excellent condition all around. They are customs so you'll have to have them reshelled. 64 will do it for $399 but I don't know about other companies' reshell services. They will come with all the original accessories and the original box. I will include both the m15 and m20 modules. The extra module is normally an extra $100 (it normally just comes with one of them). It will come with the original cable in silver (color) as well as a 2.5mm balanced version of their Premium Cable; normally an extra $139. I am asking $1200 including Paypal fees and shipping to CONUS. I will only ship to the verified address associated with your Paypal account. I will ship elsewhere but buyer pays all shipping costs. Some pictures can be found here. I can provide more, of the case and additional accessories, if you'd like.
