Currently the amp has 2281 hours so the new tubes have 601 hours one them.It is one of most 3D sounding amplifiers I have ever heard.

Audio Research I/50 Integrated Tube Amp Black w/ DAC + PHONO Modules I am selling my like new black I/50 integrated amp by audio research. I am the original owner of it. It comes exactly as it would if you bought it brand new. This is the most desirable color and speced out unit in my opinion as it comes with both the $1000 (?) DAC upgrade (which sounds AMAZING) and the same $1000 Phono Card Upgrade. This maxes out the potential of the unit and its in a sleek black color which I liked most. There are a few hundred hours on it total as it was a 3rd system for me so its literally perfectly broken in and sounds wonderful. Its a deceptively small system but when I plugged it into my Wilson Sasha 2 speakers it powered them with ample amounts of power and sounded great there and it also made these Tannoy System 1000 speakers that I used with them sound excellent as well. Due to the condition, # of hours and options I priced it at $5500 which I feel is fair since its $7500 brand new. Im open to serious offers on it and can ship quickly. Looking for an amplifier that can deliver amazing sound quality? Look no further than the Audio Research I/50 Integrated Tube Amp. This black tube amplifier offers 50 watts of power, making it the perfect addition to your home audio system. With built-in DAC and PHONO modules, it provides an impressive solution to all your music needs. The Audio Research I/50 is made by Audio Research, making it a reliable and well-designed product. With this tube amplifier, you can enjoy rich and powerful sound quality. The Audio Research I/50 is the perfect choice for anyone looking to upgrade their home audio system.

Here’s a nice Audio Research Foundation Series VT80 amp, originally in silver, now in black. I also have what I believe are some original silver trim pieces. If you want those, I will see if i can safely pack them in the original carton with the amp or you can just pay me the extra shipping cost to send a second and smaller box your way. When I got this unit I got in touch with ARC and I ordered the optional tube cage for it along with a new “Certified Matched” factory tube set featuring the SE-spec KT150 tubes. In the two years since, I’ve put just 57.9 Hours on that factory tube set. As you may know, the early units were sold as VT80 with KT120 tubes (as this one probably was). Soon after launch, they went to the larger KT150 tubes and with that change alone, these units became VT80SE tube amps. There was no other difference between VT80 or VT80SE. The SE came by virtue of a simple tube change alone. Here’s how the manufacturer explains it, better than I can: https://audioresearch.com/product/vt80se/______________________________________The big change from the VT80 to the new VT80SE is upgrading the KT120 tubes to the higher performance KT150 output tubes. Everyone should know that we have been deeply enamored with the KT150 as we feature it in all of our other amplifiers, from the VSi75 to the REF 750SE. Its performance is unparalleled and its 3,000 hour average life allows years of uninterrupted listening. The VT80 was originally designed with the KT120, the predecessor to the KT150, but these two tubes are electrically interchangeable and the demand for delivering the VT80 with the KT150 could be ignored no longer.It is important to mention that the KT150 tubes supplied by Audio Research, for all of our products, are tested and measured for quality control and assurance, and are burned in for 48 hours. Then using our “Certified Matched” process, they are hand matched in sets with tolerances 10x tighter than standard off-the-shelf tubes, thus ensuring the finest audio quality possible.With its auto-bias design, the VT80SE can also be used with KT120 or KT150 output tubes and the circuit will adjust immediately when a new tube is installed. Protective fuses are installed for each output tube and can be replaced if the need ever arises. What sonic improvements will you hear with the VT80SE? As our Warren Gehl said, “More music!” Tonal color, detail, dynamic swing and purity are all improved, along with a bigger and more robust presentation. The music gets better, in every way.Aside from the beautiful curves of the KT150 tubes, the only other way to distinguish the SE from the original VT80 is by a small sticker on the rear panel. Nothing else needed to change. The existing (optional) ventilated tube cover can be used with the taller KT150 tube set, there is still sufficient space to breathe. Hear for yourself how good your system can sound with the new VT80SE, it will make a tube-lover out of anyone who loves music.___________________________________________________Link to the manual: https://audioresearch.com/wp-content/uploads/2019/03/VT80SE-Manual.pdf The sound is phenomenal, as I’m sure you already know about these units. They engineered a first-ever auto-bias system for the tubes in these amps so you can put that little plastic screw driver away from prior AR amps! Used with care in my no-smoking home. You’ll get the manual and original power cord all in the original double-boxed factory carton.Reviewed 6 years by TAS: https://www.theabsolutesound.com/articles/audio-research-vt80se-power-amplifier/Serial #49745 for this unit and the box label is included in my photos.

Up for sale we have an Audio-Technica Digital Research DR250 Stylus never used but open box box has stickers as seen in photos. Please see pictures and email me with any questions.

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.
