It seems like the one and only repair center for Stax headphones in the USA (Accutech) is either out of business or has the worst customer service I've ever experienced. I've been trying to call them, email them, and even fax them for at least the past 2 months without a single response. It's a shame that a product of such quality can't be repaired, but that seems to be the case. Even Stax of Japan, whom I tried to contact, does not respond. Anyone have any ideas? I'm trying to get repair on a set of SR Lambda's.
