For sale is the Stax SR-007 MK1 early production version. As you can see it is the very first version with the carbon fiber case. It had a pair of Kennerton Thror ear pads installed. Which to me tighten the bass and is more comfortable. The original ear pads will also be included. Asking for $1850 shipped. Please add 3% if Paypal was used. Let me know if you have any questions or need additional photos.
