For sale is my recently acquired STAX Lambda Pro and SRM-1/MK-2 Pro amplifier.  Both the Lambda and amp show signs of use, that I feel are appropriate for their age with scuffs and scratches- but are in perfect condition operationally.

I have removed the cover from the amp in order to tighten the main PCB, as it would shift slightly in either direction if the amp was tilted.

I have completely disassembled and 'rebuilt' the Lambda Pro.  When I first received the headphone, the original foam was deteriorating and leaving foam pieces in the grills and vents.

I pulled the headphone apart, split the drivers, replaced the ear side dust shield with Glad Press n' Seal (0.5mil dimpled low density polyethylene), and reglued the entire assembly back together with Gorrilla Glue (cured under pressure for 2 hours).  The original pads were reattached with industrial double-sided tape, but I would highly recommend buying new pads as the tape shows and doesn't look the best.

I have put between 20 and 25 hours on these, and roughly half of that was after mods.

Also included to the extension cable pictured.

Payment via PayPal, shipping in the United States via UPS is included. If you are overseas and wish to purchase these, send a PM and we'll discuss shipping.
