I am selling my beloved pair of Audio Research Classic 120 monoblocks. Introduced in 1990, the CL120 is a stunning ARC design. Each amplifier leisurely loafs along while the eight 6550 output tubes produce 110 watts per channel. With these amplifiers, there is no such thing as burning ones hands on the top plate. These tubes are able to run at milder temperatures. This is a very well cared for pair, and their condition is excellent. On one amplifier, you may perceive a very small ding in the metal faceplate right underneath the Line Fuse. Thats the only flaw I know of. If your eyes spot more, you have sharp vision! The power supply of each amplifier was rebuilt in 2017 at Classic Tube Audio in Portland, by the same gentleman who designed and built world-class Whammerdyne amplifiers. Those 6 large power supply capacitors you see in each amplifier are relatively young, not 30-year-old components going wildly out of spec. Concurrently he performed a number of checks and installed high-end ClarityCap capacitors in critical locations for the best sound the amplifiers are capable of producing. Looking at the underneath photo of one of the amps, you can see the Clarity MRs and CMRs that were installed. Additionally, the built-in power cords were removed and replaced with IEC plug receptacles so the audiophile may use what power cord they choose. A couple years ago, one amplifier suffered a blown charging resistor due to a tube that was drawing excessive current. This was also repaired (quite easily) at Classic Tube Audio, along with a better set of tubes. I am including all this paperwork along with the original Owners Manual. All can be seen in the last photo. Since the CL120 has screw-on terminals for speaker cable connection, I am willing to hand over to the buyer my pair of Audioquest Slate 6-foot speaker cables that are terminated on one end with thin spades for use with these amps. You may ask, if I love them so much (and I do), why am I listing them for sale? Pretty simple. Space, life simplification. I am not the first owner of this fine pair, but I have been very dedicated to their longevity and condition. I am willing to ship these, using UPS Ground. The box for each amplifier weighs 72 pounds. eBays calculated shipping rates may seem excessive to you, based on location. If I can purchase the shipping for a lower rate (like purchasing through eBay), I will refund the buyer and shipping overages they pay. The shipping rate is calculated based on 144 pounds with a 25 x 25 x 31 size, the dimensions of both boxes put together. Shipping is to lower 48, Alaska, and Hawaii only. The original boxes, while not absolutely perfect, are in good condition for their age and are 100% usable (the amplifiers have been shipped and transported before, so the boxes have old tape and some shipping scuffs). You will receive the amplifiers packed within them. I am not accepting any third-party pickups and deliveries, nor any pick-ups that result in an international delivery. I cant run the risk of this being picked up by an unknown party, damaged in shipping, and the buyer receiving something unworkable which results in a big dispute. Any purchase that involves a third-party pickup will result in sale cancellation. Thank you for understanding.

Audio Research Ref 160M MkI Mono Power Amplifier - PAIR Color: Silver These amplifiers are in excellent condition and function flawlessly. They are consecutive serial number amplifiers and they include their original packaging, user manual, tubes (1278 hours), 20a power cords, bias adjustment tool, and cover removal tool. These amplifiers are available with freight shipping available or for local pickup in Columbus, OH. Feel free to message me your shipping zip code for a freight quote. Do not miss the chance to own these amazing amplifiers at an incredible price.After two years in development, the new Reference 160M (REF160M) Monoblock Power Amplifier is built like no other, looks like no other, and sounds like no other amplifier that you have ever heard, but it is unmistakably Audio Research. It features a refined audio topology with fewer and better components in the signal-path than in previous designs, switchable Ultralinear/Triode operation, proprietary auto-bias, output tube monitoring and protection, an advanced power meter, and much more. This array of features has never been offered before in an Audio Research amplifier. The designers at Audio Research wanted to create a new style that would complement the look of the REF6 preamp while also featuring a transparent faceplate that allows a view of the glowing KT150 vacuum tubes. While this window allows you to see the output tubes, it also incorporates an innovative dual-layer construction with distinctively etched markings that create an integrated power meter. The power meter’s output-level markings illuminate via hidden LEDs, and the illumination brightness is adjustable. The REF160M includes a sculpted cover with an integrated fan to cool the heat generated by the four (4) KT150 output tubes and two (2) 6H30 driver tubes. Solid-state power regulation was chosen to provide increased efficiency, stability, and reliability. The power supply stage uses a newly developed High Energy Capacity Transformer and a hefty bulk storage-capacity network to provide extremely high current on demand for transient peaks and intense dynamics, as well as for prodigious bass depth and authority. It is understood that the best path is the shortest path. Audio Research engineers created a new audio circuit topology with the shortest signal path and the fewest components. Those components are not only the best available, many are custom made for Audio Research. Incorporating these quality components is a special 4-layer circuit board that lowers the noise floor to unprecedented levels, and a design which was previously reserved for use in our preamplifiers. The result is a new benchmark in musicality in every criterion of sound quality.The REF160M also features a proprietary auto-bias circuit that works with various tubes types, including 6550, KT88, and KT120, in addition to the supplied KT150 and works constantly to maintain precise bias of the output tubes, while also adjusting for tube wear. There is no need to check or adjust bias ever again.The new REF160M breaks new ground sonically, aesthetically and operationally, and will be available in Natural (Silver) or Black finishes.POWER OUTPUT140 watts continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 1% at 140 watts, below 0.04% at 1 watt.

Audio Research Ref 750 SE Tube Mono Power Amplifier - PAIR MSRP: $70,000 These amplifiers are in excellent condition and function flawlessly. They are consecutive serial number amplifiers and they include their original packaging, user manual, tubes (0.2 hours), and 20a power cords. These are hailed as some of the best tube amplifiers in the world and they rarely come up for sale. This pair has ultra low hours (0.2 total hours) on them and are nearly brand new. These amplifiers are available with freight shipping available or for local pickup in Columbus, OH. Feel free to message me your shipping zip code for a freight quote. Do not miss the chance to own these amazing amplifiers at an incredible price. Listening to Reference 750 SE monoblocks in a high performance system is a transformative experience; under total control, speakers disappear from the listening room and the listener is transported into a three-dimensional realm where music takes on a palpable, tangible form. Details from source material are resolved against a black background, painting images in space with vivid reality. Bass becomes the foundation on which this living performance develops, produced with startling temporal and timbral accuracy. Here is the breath of the performer, the pick against the string, the brilliance of a full orchestra. The Reference 750 SE is prepared to deliver 750 watts of power into speaker loads of 4, 8 and 16 ohms. This is achieved by the use of a massive, custom- built power transformer delivering current from sixteen KT150 vacuum tubes. Thanks to extensive testing and strict selection of tubes, the amplifier requires little maintenance and obviates the need for costly and sonically deleterious automatic bias systems. Power supply regulation is also achieved by 6550WE and 6H30 vacuum tubes. Tube bias is controlled by two KT150 tubes, each driving a bank of eight tubes.POWER OUTPUT750 watts per channel continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 0.5% at 750 watts, below .04% at 1 watt. Approximate actual power available at “clipping” 850 watts (1kHz).
