A wonderful tubed power amp from AR that was a real match for its REF 110. This model was factory upgraded with the new KT 120 tubes, now used in all the AR power amp models. The hallmark of this amp is soundstaging, slam, detail, and control. Matched with an AR preamp you will be highly satisfied for a very long time indeed. Amp comes in original factory carton and wrapping, original manual, foam tube blocks with KT 120 tubes (only 500 hours on them). The unit is packed and ready to ship. Price is now reduced to rock bottom, far below what my dealer feels I should charge. Serious inquiries only, please.
