Audio Alchemy repair


I am experiencing intermittent sound dropouts from my AA DAC and am looking for someone who might be able to fix it. Anybody know a repair tech for these?

... not to mention that there have been a "few" advancements in DAC performance in the last dozen years since AA closed down.

Also, I'm sure you can pick up a used one from eBay for a lot less than you could get one fixed IF you could get one fixed.
