The term ‘reference’ still has meaning for Audio Research, and it doesn’t use the term lightly. The Reference Phono 3 is a true reference point in turntable replay, as it extracts a remarkable amount of information from the cartridge, and yet plays it in a manner that invites you to listen to more and more albums. Those hundreds of hours of run-in will never be viewed as a chore, more as a pleasure, unveiling both what your records are capable of and just how much better your Reference Phono 3 gets. And those hundreds of hours will pass quickly, too. From a position of not firing the ejector seat on my own career at least, there can be no ‘best’ in high-end audio, but the Audio Research Reference Phono 3 is one of those rare devices that gets closer to ‘best’ than most. Highly recommended. - Alan Sircom, Hi-Fi + Functional Notes: Operational condition of this item is excellent, fully tested and no issues found.

Magnificent sounding pair of Audio Research Balanced Tube Mono blocks with over 200 glorious tube watts of power enough to drive almost any reference loudspeaker. This pair uses 8 KT120 tubes per channel and, unlike the recent power amplifiers from ARC that use solid state power regulators, uses a tube regulated power supply with a 6550 tube. I have run many loudspeakers with these mono blocks and compared them to many other state of the art amplifiers. I have not found anything that comes close to the majestic sound of these behemoths. They are simply unparalleled in my listening experience with both electrostatic and dynamic speakers. This pair is offered with a complete set of two unused brand new tube sets (32 KT 120 power tubes) besides the 16 KT 120 tubes already in the amplifiers. That’s roughly 48 KT 120 tubes that at current market prices for these tubes is worth several thousand dollars. You will not need new tubes for a long while with these amplifiers. Some points to keep in mind in deciding whether to buy these amplifiers: 1. These are large fan-cooled tube amplifiers that are fully balanced. You’ll need the place them in a room with sufficient ventilation as they run pretty warm. 2. I used these with ARC Reference tube preamplifiers. You can use them with other balanced preamplifiers or DACs that have a volume control. 3. The Bluebook value as attached is around $5000, which does not include the two spare new tube sets I am including with mine. Do your research and see what 32 KT 120 tubes cost (mine are factory matched octets, which are being sold on eBay for $1000 per octet). 4. Check the weight and size of these amplifiers. They are around 90 pounds each in their factory boxes. Shipping costs will be considerable. No international shipment of these amplifiers. I welcome local pickup if you are in the San Francisco Bay Area. 5. The physical condition is as shown, and reflects several years of use. The front panel looks as shown in the pictures. The covers are fastened with a lot of screws, and I think I’m missing a couple of screws on each amplifier. But each amplifier cover is held with over 20 screws, so they are plenty there to hold each panel tightly. 6. The custom made wooden stands are not included with the sale. 7. This is a top of the line audiophile amplifier. Don’t bid unless you know what it takes to set up and install each amplifier. Bias for each power tube is set with two remote controls as shown. Unlike current ARC amplifiers, these use a digital power meter and bias values are shown in a large digital readout (which I prefer). 8. These are considerably more powerful than the largest current model 160M ARC amplifiers that cost close to $35,000! At this price, they are a bargain! They are so well built that they will last a lifetime with careful use. 9. Keep in mind there are two boxes, one for each amplifier. On Mar-14-24 at 16:39:00 PDT, seller added the following information: Added the option of local pickup. Also wanted to add that the amplifiers will come with two custom made plastic covers.

I have for sale some very rare Audio Research gold plated, machined metal knobs. These are (new old stock) knobs that were in storage for a number of years and have never been installed in equipment. The overall condition of the knobs is very good. Two of the knobs have some minor scratchs on the side which is only noticeable on close examination. The knobs are from the estate of an Audio Research employee. Im selling (4) knobs in my ad as pictured, The knobs will fit any Audio Research preamplifier that starts with an SP and take 4 knobs. Such as the Audio Research SP-4, SP-5, SP-6, SP-7, SP-8 SP-9, Note: The knobs will not fit the Audio Research LS series of line stage preamplifiers. One thing worth mentioning...the knobs have a shiny gold surface, so its very hard to get a good picture of one knob or a group of knobs. If you are unsure if the knobs will fit in your Audio Research piece of equipment, please email me before buying the knobs. Continental USA shipping only, No International sales.

Shunyata Research Venom 14 NR Digital with IEC C13 connection. Beats the pants off many quality power conditioners. Condition is Used. $399 New. Ships for Free. Includes original box and manuals. Specifically designed to be used with Digital only devices with no analog output to maximize noise reduction. From Shunyata.com: AWARDS & REVIEWS APPLICATIONSIdeal applications include devices that use very noisy switched mode power supplies (SMPS) including computer peripherals, music-servers, NAS arrays, routers, switches, monitors, clocks, up-samplers, digital transports, wall warts, and power bricks.Only available with US AC plugs. TECHNOLOGYNR NOISE REDUCTIONShunyata Research’s exclusive NR (Noise Reduction) technology is a multi-stage filter network that measurably reduces power-line and component-generated noise, producing better purity of tone and clarity. It delivers a stunning background of silence to recordings, allowing the listener to hear into recordings as never before. Every nuance of meaningful content is revealed, bringing to life music’s most consequential moments as if the performers are in the room with the listener.DYNAMIC TRANSIENT CURRENT DELIVERYDTCD™ Analysis is a technique that measures instantaneous current through low impedance electrical conductors and contacts. Shunyata Research uses it to optimize the design, specification and construction of parts and materials to ensure maximum current delivery performance. Each part, conductor, noise circuit and material allows for maximum throughput of instantaneous current.Listeners will experience earth-shaking low-frequency performance from even the highest-current amplifiers as well as dynamic contrasts unheard of outside of a live event. More than any other design parameter, Shunyata Research’s skill in eliminating resistance and maximizing peak-current delivery is unmatched.OFE Alloy 101Shunyata Research uses only the highest purity of copper available for the production of its wire products. OFE Alloy 101 or C10100 is the highest grade of copper with a minimum 99.99% purity and a conductivity rating of 101% IACS. OFE stands for oxygen-free electrolytic and supersedes the term OFHC (oxygen-free high conductivity). C10100 is the only grade of copper that comes with a written certification of purity.Certified by ASTM F68 C10100Fluorocarbon dielectrics are usually only found in wire used in the aerospace industry, satellites and only the most expensive audiophile cabling. It has special electrical characteristics; very low dielectric absorption, high dielectric strength and exceptional heat resistance. When used in audio and power cables is reduces the perception of dynamic compression and it improves sonic low-level resolution and clarity.Crystal clear transient detail.Audiophile Grade ConnectorsShunyata Research audiophile-grade connectors are made from a high-grade brass-copper-zinc alloy that can accept the very large 08 gauge conductors. The polycarbonate head-shells provide a lifetime of longevity.Hermetically SealedThe connectors are hermetically sealed with an electrically inert compound that protects the contacts and wires from corrosion. The compound also ensures that the wires cannot become loose, fray or pull out from the head shell. This guarantees a lifetime of reliable performance that does not degrade over time.KPIP™ PROCESSINGShunyata Research’s proprietary Kinetic Phase Inversion Process includes four days of continuous KPIP™ processing to dramatically reduce burn-in time and significantly improve sonic performance, delivering a relaxed and life-like presentation.

Capacitors are all the same types as those used in the REF Phono 2, including the same coupling caps, and Teflon® caps used in both the RIAA stage and as bypass caps. There is also a new R-core transformer. Circuit board material is the same as in our Reference products. Bandwidth is extraordinary, with -3dB points below 0.3dB and above 400kHz.
