I am the original owner of these amps having purchased them brand new through an authorized Audio Research dealer. These amps have about 900 hours on them. There are absolutely no cosmetic or operational issues. Those in the know feel these are the finest amps ever produced by Audio Research. They are "the" reference amps in the AR lineup utilizing the KT120 power tubes and offer the latest innovations derived from the Ref. 40th Anniversary preamp. All original tubes, accessories, power cords, owner's manual and shipping boxes are included. Inquiries can be sent to firstname.lastname@example.org.
