They are consecutive serial number amplifiers and they include their original packaging, user manual, tubes (0.2 hours), and 20a power cords.

These amplifiers are available with freight shipping available or for local pickup in Columbus, OH. Feel free to message me your shipping zip code for a freight quote. Do not miss the chance to own these amazing amplifiers at an incredible price. Listening to Reference 750 SE monoblocks in a high performance system is a transformative experience; under total control, speakers disappear from the listening room and the listener is transported into a three-dimensional realm where music takes on a palpable, tangible form. Details from source material are resolved against a black background, painting images in space with vivid reality. Bass becomes the foundation on which this living performance develops, produced with startling temporal and timbral accuracy. Here is the breath of the performer, the pick against the string, the brilliance of a full orchestra. The Reference 750 SE is prepared to deliver 750 watts of power into speaker loads of 4, 8 and 16 ohms. This is achieved by the use of a massive, custom- built power transformer delivering current from sixteen KT150 vacuum tubes. Thanks to extensive testing and strict selection of tubes, the amplifier requires little maintenance and obviates the need for costly and sonically deleterious automatic bias systems. Power supply regulation is also achieved by 6550WE and 6H30 vacuum tubes. Tube bias is controlled by two KT150 tubes, each driving a bank of eight tubes.POWER OUTPUT750 watts per channel continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 0.5% at 750 watts, below .04% at 1 watt. Approximate actual power available at “clipping” 850 watts (1kHz). (Note that actual power output is dependent upon both line voltage and “condition” i.e.: if power line has high distortion, maximum power will be affected adversely, although from a listening standpoint this is not very critical.)POWER BANDWIDTH(-3dB points) 15Hz to 150kHzFREQUENCY RESPONSE(-3dB points at 1 watt) 1 Hz to 200 kHzINPUT SENSITIVITY4.6V RMS Balanced for rated output.

I/50 Overview from Audio Research Corporation The I/50 Integrated Amplifier is the first product in an all-new series from Audio Research. Functionally simple, visually engaging, and musically sublime – the I/50 takes music listening to a whole new experience. Hand-crafted in Minnesota, the I/50 is built with the same attention to detail as all other Audio Research products – each one even gets its own listening test with sonic designer Warren Gehl. The I/50 features a Cerakote finish for a beautiful, long-lasting look. The modular design allows for the installation of two audio modules – a Phono Stage and a D/A Converter. The high current, 50-watt per channel amplifier is capable of driving a wide variety of speakers. A headphone jack allows for personal listening time.The I/50 is designed to be easy to use and has three controls on its top panel – Power, Input, and Volume. Two LexieTubes® provide display information for input selection and volume. Two matched pairs of 6550WE vacuum tubes, along with three 6922 tubes, stand in front of the perforated transformer cover. Three single-ended inputs and one XLR input provide connectivity for most systems, along with 4- and 8-ohm speaker taps to accommodate your speaker of choice. One input can be assigned for pass-through function. A full-function metal remote control provides further functionality and operation. An optional tube cage will be available.As with all Audio Research products, the I/50 is built entirely in our Minnesota facility by a team of skilled technicians and expert craftspeople. Offered in six colors, the I/50 is the first product completely finished in-house. The Audio Research finishing lab encompasses a purpose-built painting facility and laser imaging and marking machines to produce a luxurious finish normally found only on much more expensive products. The Cerakote finish is not only beautiful, but designed to be enduring and easy to maintain.The performance of the I/50 belies its compact design. 50 watts of all-vacuum tube power energize your speakers with beautiful and lifelike music. Designed by the Audio Research engineering team and fine-tuned by Warren Gehl, the I/50 has been given the same level of care and attention as our Reference Series products. The ability of the I/50 to reconstruct a musical experience will thrill and excite all who hear it. The I/50 provides controlled and dynamic playback – even on challenging speakers thanks to the substantial power supply and high current design. The Phono module provides 42 dB of gain, allowing a wide choice of moving magnet and high-output moving coil cartridges. The D/A Converter will have multiple connection options and an array of decoding formats to accommodate the wide spectrum of music formats and resolutions. The I/50 is a truly integrated product that provides renowned Audio Research performance and sound quality.

Im Kundenauftrag bieten wir hier echtes Highend aus dem Phonobereich. Die Weltklasse-Phonovorstufe PH-8 aus der amerikanischen Hifi-Edelmanufaktur Audio Research setzt hier sicherlich Maßstäbe und gehört zu den besten am Markt. Die Vorstufe gehört einem langjährigen Stammkunden und Freund unseres Hauses und wird daher in seinem Auftrag verkauft. D.h., es ist somit ein Privatverkauf und der dieser findet unter Ausschluss der Gewährleistung statt. Selbstverständlich kann sie hier Vorort begutachtet werden. Zudem bleibt hat der Käufer ein 14-tägiges Rückgaberecht, so dass er das Gerät auch in Ruhe testen kann. Angebotsumfang: Die Vorstufe mit FB, Manual und OVP Fragen beantworten wir gern. Wir nehmen übrigens auch Geräte in Zahlung. Auf Anfrage machen wir Ihnen gerne ein entsprechendes Angebot. Bitte schauen Sie auch einmal in unseren Ebay-Shop Hifi-Dortmund. Dort finden Sie in der Regel zahlreiche interessante Angebote aus den Bereichen Hifi und High End Hifi. Bitte haben Sie Verständnis, dass wir diesen Artikel keinesfalls versenden werden. Das Gerät eignet sich aufgrund der Beschaffenheit und/oder des Gewichts nicht zum Versand. Das heißt, er muß in unserem Geschäft in Dortmund abgeholt werden. Bitte bedenken Sie das auch bei etwaigen Rückgaben. Wenn Sie das nicht können oder wollen, bitten wir Sie, vom Kauf abstand zu nehmen. Daher eher etwas für Interessenten aus der Region. Vorbesichtigung und Probehören gerne vorab möglich. KEIN VERSAND! Das Gerät gehört uns nicht und wir wollen keinen Versandschaden riskieren. Grundsätzlicher Hinweis zu unseren Angeboten! Wir sind niemals Erstbesitzer und können daher praktisch kaum eine lückenlose Historie garantieren. Auch können wir nicht garantieren, ob sich die Geräte noch im Originalzustand befinden. Wir sind da auch meistens auf die Angaben der Vorbesitzer angewiesen, die wir dann unsererseits, wenn keine Anhaltspunkte zum Zweifel erkennbar sind, unverändert weitergeben. Die Zustandsbeschreibung ist stets eine subjektive, die unsere Einschätzung wiedergibt. Das es zu unterschiedlichen Einschätzungen kommen kann ist natürlich möglich. Fast immer handelt es sich um Gebrauchtgeräte und nicht um unberührte Neuware. Bitte haben Sie Verständnis, dass wir nachträglich nicht in Preisverhandlungen eintreten werden, weil dem Käufer der Artikel nicht zusagt. Wenn das Gerät nicht den Erwartungen entsprechen sollte, kann der Käufer das Gerät im Rahmen des Rückgaberechts wieder retournieren. Auch bitten wir zu beachten, dass bei älteren Geräten die 10, 20 oder mehr Jahre alt sind stets altersbedingt Bauteile ausfallen können. Zudem können wir nie garantieren, dass die Geräte wie am ersten Tag spielen. Auch hier kann es die ein oder andere Alterserscheinung von Bauteilen geben. Weiter können bereits Bauteile in der Vergangenheit gewechselt worden sein. Wenn nicht ausdrücklich anders erwähnt, werden alle unsere Verkäufe gem §25a UStG vorgenommen, so dass keine MwSt ausgewiesen werden kann.
