{"product_id":"leben-cs-600x-0634","title":"Leben CS-600X Integrated Tube Amplifier (Used)","description":"\u003cp dir=\"ltr\"\u003eA used Leben CS-600X in excellent, like-new condition. Please see pictures for condition details. Please note that no factory warranty applies. The CS-600X is Leben's flagship integrated amplifier, hand-built in small numbers at the company's factory in Japan and representing one of the most thoughtfully engineered and musically satisfying tube amplifiers available at any price. It is the evolution of the celebrated CS-600, updated with a new first-stage tube complement based on the 6CS7 twin-triode, which brought improved availability and compatibility compared to the tubes used in its predecessor.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe output stage ships with four EL34 (6CA4) tubes as standard, delivering 28 watts per channel in ultralinear Class AB operation, and accepts 6L6GC\/5881 tubes with a simple internal selector switch — raising output to 32 watts per channel and offering a distinctly different tonal character. KT66, KT77, KT88, and 6550A tubes are also compatible, giving the CS-600X a degree of tube-rolling flexibility that is genuinely rare among integrated amplifiers. Front-panel LED indicators show at a glance which tube type is currently selected. A four-position output impedance selector covering 4, 6, 8, and 16 ohms ensures an optimal match with virtually any loudspeaker, and the heavy-duty output transformers are wound in-house by Leben — engineered to 50-watt grade specifications for exceptional headroom and frequency response extending to 100kHz.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe power supply uses a NOS 6DN3 rectifier tube with a large 5-henry, 350mA smoothing choke to reduce ripple, and a 6CJ3 damper tube delays the application of high voltage to the output tubes at power-on for enhanced tube longevity. All internal wiring is point-to-point, using audiophile-grade capacitors and resistors throughout. Five single-ended RCA inputs, a tape loop, a preamp-in bypass allowing power amplifier direct operation, a headphone output, 24K gold-plated knobs, WBT-style speaker terminals, and beautifully crafted side wood panels round out one of the most complete and characterful tube amplifiers built today.\u003c\/p\u003e","brand":"Leben","offers":[{"title":"Default Title","offer_id":45937950031925,"sku":null,"price":7995.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0632\/1704\/1461\/files\/CS-600X-0634a.jpg?v=1787843191","url":"https:\/\/alleliteaudio.com\/products\/leben-cs-600x-0634","provider":"All Elite Audio","version":"1.0","type":"link"}
