Description: Mint condition REF110 stereo power amplifier – updated with premium ARC KT120 output tubes for approximately 125W pch; ~800 hrs on ARC driver tubes and output tubes. Front panel has flush screws instead of handles, reducing depth by ~1.5”.

ARC description: A major reason that our Reference products have been so successful is that each offers great value-the remarkable performance each provides had simply not been available near its price. Now, the Reference 110 will redefine expectations and value in a truly state-of-the-art stereo amplifier. It is perfect for anyone who does not require the high power provided by our larger monoblock Reference amplifiers.

Each channel is based upon a push-pull, fully balanced circuit utilizing two matched pairs of KT120 output tubes . The input stage utilizes direct-coupled JFETs with a 6H30 gain stage and 6H30 cathode-follower. Output stage coupling is a combination of "Ultralinear" and Audio Research's "partially cathode-coupled" topology, yielding better sound than conventional pentode or triode operation. Note that the REF110 requires balanced differential inputs and will not work with single-ended sources.

The REF110 is truly a Reference product, maintaining the musical presentation of its larger siblings. The REF110 is simply revelatory, displaying an irresistible combination of grainless detail, refinement and dynamic life with bass definition, impact and control. As original owner of this REF110, I also own the REF150SE with KT150s. The REF110 is similar in design and very close in spatial detail articulation and dynamics; and only somewhat weaker than the REF150SE in bass dynamics and authority.

For state of the art vacuum tube sound, don’t waste your time with older vintages or amps with non-ARC-supplied output tubes of >800 to 1000 hrs use. For optimum sound, output tubes should be replaced after ~1300hrs.

Money order, bank cashier check, or PayPal with local pickup in Menlo Park, CA. Otherwise add 2.9% PayPal fee and estimated cost for shipping and insurance with purchase. Price firm.
