We only buy equipment that we admire and are passionate about. No mid-fi, no gimmicks, no junk. We also represent a small number of carefully selected "best in class" high-end brands like McIntosh, Klipsch, Technics, Sumiko, and HiFi Rose. These are new products fresh from the factory. Each pre-owned 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.
