WHO WE ARE
SkyFi Audio is a small startup business specializing in the purchase, reconditioning, and reselling of select high end audio equipment. We only buy equipment that we admire and are passionate about. No mid-fi, no gimmicks, and no junk.

Each piece of equipment is cosmetically restored and fully tested in our well-equipped lab by an engineer with 30+ years of experience in the HiFi world. If it does not meet or exceed the original manufactures specifications, it will not be sold. We are very selective about the equipment we purchase, focusing on mostly analog, high-build quality, American, and European built units.
