One (1) original Audio Research Reference 6 preamplifier metal remote. Working condition without problem.

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

Youre looking at a one owner preamp thats in a spare home that we really dont use. I have the box, manual, remote, power cord. The unit is barely broken in. - ONLY ARC REF 6 IS FOR THE ADD - MBL GEAR WILL BE LISTED AFTER PREAMP IS SOLD. 00MD INSTAGRAM

Audio Research SP9 MKII Hybrid Stereo Tube Preamplifier *The SP9 was sent to Audio Research in April of 2023 for inspection and a general check-up before listing it on ebay (see picture with specific details of what they addressed and fixed). It was returned in May 2023 with a clean bill of health. I no longer use tube audio gear, and this fantastic sounding preamplifier needs a new home. I’ve owned it for 20 years and am the third owner. Audio Research tested the tubes in the SP9 and they are ok -- there are three different sets of tubes with life left on all of them, and I would recommend swapping them in/out to see what sound you prefer. They also recommended the gain control could be adjusted which I passed on due to it not making any changes to the sound quality.

Audio Research LS3 Preamplifier Super Clean Condition Working Perfectly and extremely quite low noise MADE IN USA Description : The Audio Research LS3 preamplifier is designed to last through its elegant engineering design, exacting selection of quality components and intelligent, caring manufacture, and retaining remarkable value well into the future. It features an all-new circuit design that combines a shortest-signal-path layout with minimum of point-to-point wiring, D.C.-coupled inputs and a tightly regulated power supply. The input selector switch is board-mounted as close to the inputs as possible, and for extra high-purity input sources there is the Direct Gain Path, which bypasses all controls and switching functions except for Gain. It has enough inputs and outputs to allow connection to many sources and to a video surround-sound processor. The Audio Research LS3 has two sets of single-ended outputs, so two separate power amplifiers can be easily driven in a bi-amped system. The Audio Research LS3 preamplifier runs silently without coloring the music especially at low volumes. It has great depth and detail, but the program source makes the biggest difference. Poor recordings can sometimes sound quite harsh, yet good recordings just blossom with impact, speed and realism. The LS3 is stunning in its clarity, detail and utter simplicity. From small ensemble baroque to big symphonic pieces, the LS3’s performance is beyond reproach. Voices are very lifelike, smooth and clear, and lyrics of the song can be easily heard and understood. The detail runs deep into music and every single instrument on recordings is clear and well separated. The Audio Research LS3 preamplifier plays without adding any its own signature, and reproduces astounding resolution of musical detail, with wide-open dynamics.

The worlds largest online retailer of pre-owned audio Product DescriptionWho we areWhat we doOur ProcessOur Policies Audio Research PH8 MM / MC Tube Phono Preamplifier; PH-8; Remote Product SKU: 49264 Voltage: 120V # of Owners: 1 Service History: None Serial Number: 47582 Age: Unknown Tobacco Exposure: No MSRP: $6995 Cosmetic Description: Excellent condition with no notable blemishes.  What is Included: Preamplifier, Remote, Manual, One Sovtek 6550WE tube, Three Sovtek 6H30n-EB tubes, Power cable, Factory packaging Other Notes: Tube hours: 3504 The PH8 benefits from a number of circuit and parts improvements derived from the award-winning REF Phono 2. Rather than using the four 6922s of its predecessor, the PH8 uses two 6H30 tubes along with special low-noise FETs; vacuum tube regulation incorporates a 6550 and a 6H30, as featured in the REF Phono 2 and REF5. 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. Distortion is vanishingly low, and gain is a very healthy 58 dB, allowing the PH8 to be used with low output moving coil cartridges and an appropriate line stage. - Audio Research Functional Notes: Operational condition of this item is excellent, fully tested and no issues found. Shipping: Cost to ship this item within the contiguous United States is a flat rate of $65- including packaging and insurance.

I am selling my beloved Audio Research equipment as I have no longer any use for it in my new home. I am selling both an SP9 Preamp and the D-115 Stereo Power Amp, but this auction is ONLY for the SP9 Preamp. It has been single owner since being purchased new decades ago, in a smoke-free home and well cared for. It has not seen much use or any maintenance in a while, but I powered it on and enjoyed it one last time before listing to ensure it works well as-is, and to me it sounds the same as it always has. It will come with as much of the original documentation/manuals as I can find - I think I have the original purchase order, too, if interested. I will not ship this, so local pickup only. All bids must be honored, and all sales are final. Any questions, dont hesitate to ask. Happy to provide more images/documentation if needed. Thanks for looking!
