Original owner Audio Research PH6, less than 50 hours on the tubes. Not sure if it's even close to it's standard initial run-in period. Unit itself purchased from authorized dealer, about 11 months old. I caught the analog bug real bad and have upgraded to a Aesthetix Rhea Signature, and need to find this a loving home. Super quiet phono stage. No blemishes, no nicks, no dust, non-smoking environment, no nothing, tubes in perfect condition. Remote was just used for first time to verify functionality. It is really a 10/10. I have all the original documentation, packaging, box, etc. all reasonable offers will be entertained, priced to sell fast.
