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.

Used, in very good condition. Tested and works perfectly. This is one preamp that will help you reach for the stars without burning a hole in your wallet. The LS-7 is a straightforward, no-frills unit (its line stage only and no remote control circuitry) that packs four 6922/E88CC tubes. In fact, there are only two main controls on the unit input selection and gain control. When you peer though its top cover, the layout is simple but very effective. Specifications: Frequency response: 1Hz to 100kHz Total harmonic distortion: 0.01% Gain: 13dB (line) Signal to noise ratio: 102dB (line) Output: 2V (Pre out), 25V (Pre out Max) Valve complement: 4 x 6922/E88cc Dimensions: 480 x 134 x 260mm

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.
