    This amp is virtually in Perfect condition and looks and sounds beautiful. You get the magic midrange of a Tube Amp with low end control of a Solid-state Im moving to a horn speaker now so this is way overkill in terms of power. My loss your gain. 100% Positive Rating and on Ebay for over 22 years. Buy with confidence. Amp Sold for $12,995. You can have this amazing world class amplifier for a small fraction of the MSRP. Very heavy. Buyer pays actual shipping. $250 (insured) Here is Stereophliles review: The Reference 150 worked flawlessly during the entire listening period, with almost no drift in tube bias, and superb bias matching between pairs of KT120s. I also found the rear fans to be effective, and quiet enough to never bother me, even during the subtlest listening sessions.Did the Audio Research Reference 150 play music in a manner so lifelike that I couldnt distinguish it from the real thing? No. The inherent limitations of recorded sound still made their way into my listening. However, those artifacts of audio reproduction were significantly fewer through the Reference 150 than through every other amplifier I have used. With its open soundstage, neutral tonal balance, finely textured musical presentation, wide dynamics, and supremely musical feel, the ARC Reference 150 connected me with my music better than almost every other amp Ive heard. Yep, thats a big statement, but one Im willing to stand behind.The Reference 150 may not have enough power for the most inefficient speakers or the biggest rooms, but in every other regard I feel that this Audio Research is the amp to beat. The asking price of $12,995 is more than justified by the Ref150s performance and build quality than are the prices of many other audio products. The Ref150 is an obvious candidate for Class A of Stereophiles Recommended Components, and marks a dramatic improvement in power amplifiers from ARC. I hope each of you gets a chance to hear one in a good system. Though my ultimate reference for music remains the real thing, the Audio Research Reference 150 is my new reference power amplifier.

    The worlds largest online retailer of pre-owned audio Product DescriptionWho we areWhat we doOur ProcessOur Policies Audio Research Reference Phono 3 Tube Phono Preamplifier; MM / MC Phono; Silver Product SKU: 52090 Voltage: 120V # of Owners: 1 Service History: None Serial Number: SN48268 Age: 1 Year Tobacco Exposure: No Cosmetic Description: Very good condition with minimal visible cosmetic wear including minor scratches on the clear top cover panel of the chassis. This item looks like new from just a few feet away. Youll have to examine very closely to find any signs of wear. What is Included: Phono Preamplifer, Upgraded remote, Standard remote, Seven Sovtek 6H30Pi tubes, One Sovtek 6550WE, Power cable, Factory packaging Other Notes: Tube Hours 2289 Integrated MM / MC Phono stage. 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.

  • Description

    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.

    Here’s a nice Audio Research Reference 5SE Preamp in black. I bought it used a couple years and promptly ordered a new tube set from the factory. In the two years since I’ve put just 53 Hours on that factory tube set. The sound is phenomenal, as I’m sure you already know about these units. They integrated some of their Anniversary (two-unit) preamp technology into this single-box unit and it shows! Used with care in my no-smoking home. You’ll get the remote, manual and original power cord all in the original double-boxed factory carton. See a separate listing for my VT-80 auto-bias tube amp (also in black) with new KT-150 tubes and the optional tube cage. Also selling my PS Audio DirectStream Mk I DAC with the streaming Bridge II module.Stereophile Review from 2012: https://www.stereophile.com/content/audio-research-reference-5-se-line-preamplifier
