Thank you DefCon for your prompt response The 407 is a 400$ HP, repairing the Signatures with 407 drivers would probably cost more! Will send the Stax to a friend who repairs Quad electrostatics, maybe he can fix it. Meanwhile, will keep a close look for impressions of the newly released L-700
This is my first post on this forum and I am seeking your advice. I have a Stax Lambda Signature that I bought in 1993. The HP was stored for a very long time and is not in operating condition. The drivers' membranes (or dust covers if any) are wrinkled, the foam covering the membrane has decayed. Is a Stax Lambda Signature repairable? Compared to current production Stax (thinking of the new L-700) is the Lambda Signature still competitive sound wise? is it worth repairing or I am better off buying one of the current models?
