Stax SR-Lambda Signature electrostatic earspeakers. Late 80s vintage. Acquired from an estate sale.  Decent used cosmetic condition. See photos for details. Has not been tested. It seems that they require a special amp. Long cable with 5-pin connector. I am not an audio person but I would be happy to answer any questions that I can. Sold AS-IS. NO RETURNS.
