The Classic 60 Hybrid Stereo Power Amplifier resembles the long-popular D115 in Audio Researchs family of High Definition® power amplifiers. But its lineage is strictly Classic 150. Which means nothing less than state-of-the-art in design, construction, musicality, and operational convenience...at an affordable price. Like the Classic 150, the Classic 60 proceeds from the notion that power ratings dont always describe a power amplifiers real capabilities. Far more important are such qualities as dynamic stability. lucidity, subtlety. And to achieve those, Audio Research has used its traditional partial cathode coupling along with triode operation of the Classic 60s eight 6550 power output tubes. Additional circuit improvements, as well as the usual rigorous parts selection and manufacturing Audio Research, are noted for, also contributing sonically. Translated into the language of listening, this signifies stunning bandwidth, a noise floor virtually beneath audibility, and musically fulfilling SPLs at dramatically lower gain settings. Dynamics, timbres of individual instruments, soundstage, and musical emotion all surge out from a black velvet of silence. Simply put the Classic 60 resolves far more of a musical program than amplifiers rated at two, three, or four times its seemingly modest 60 WPC. But the Classic 60 is easily up to the task of driving all but the most demanding loudspeakers, even in spacious listening rooms. And while it shows modest preamplifiers in their best light, it also shines when coupled with premiere designs, such as Audio Researchs SP14 or SP15. Convenience figures are high on the Classic 60s list of attributes, as well. For example, the DC balance of the output tubes is maintained automatically, while tube biasing continuously adjusts to changes in incoming line voltage. Performance stays razor-sharp without bothersome tweaking or adjustments. And quiet fan cooling, along with triode operation, means significantly longer tube life. A Classic 60 owner can look forward to years of low-maintenance performance POWER OUTPUT60 watts minimum continuous at 16 ohms from 15Hz to 20kHz with less than 1.0% total harmonic distortion. Typically below .005% at 1 watt. The approximate actual power available at clipping: 62 watts.

Zum Verkauf bieten wir hier eine überragende Röhren-Endstufe aus der amerikanischen Edel-Schmiede Audio Research. Es handelt sich um das Modell VT-100MKIII, welche mit einer Leistung von 2 x 100W angegeben ist. Via Boxenterminals kann die Impedanz auf 4 oder 8 Ohm eingestellt werden. Als Eingang stehen sowohl Cinch- als auch XLR-Buchsen zur Verfügung. Im Gegensatz zu den meisten unserer angebotenen Geräte, wird diese Endstufe im Kundenauftrag, also als Privatverkauf unter Ausschluss der Gewährleistung verkauft! Die Endstufe stammt aus 1. Hand und wir diese auch angeschlossen und sie ist natürlich funktionsfähig. Das Gerät stand jahrelang verpackt im Schrank und hat daher nur wenig Betriebsstunden und ist daher auch in einem entsprechend gutem, beinahe neuwertigem, Zustand. Die Endstufe kann selbstverständlich bei der Abholung (nur Abholung möglich!) ausgiebig begutachtet und getestet werden. Angebotsumfang: Die Endstufe, 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! NO SHIPPING! 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. Unsere Öffnungszeiten: Mo-Fr: 14:30 - 18:30 Uhr und Sa: 10:00 - 14:00 Uhr
