Bang & Olufsen - Beogram CD 6500 Serviced by B&O CD player

Bang & Olufsen Beogram CD 6500 compact disc player, designed by Jacob Jensen and manufactured in Denmark (circa 1989–1991). The unit has been technically refurbished and is once again fully functional, so the loading mechanism, disc recognition and playback work reliably. Visually the device has been refreshed and the housing looks noticeably neater than before, with light signs of use appropriate to its age.

Within the flagship Beosystem 6500, the Beogram CD 6500 forms the digital hub, characterized by its ultra-slim profile and sleek aluminium finish. Behind the minimalist front panel lies high-quality industrial technology: the renowned Philips CDM-4 swinglearm system combined with a dual 16-bit digital-to-analog conversion with fourfold oversampling. This combination is known for its unmatched reliability, excellent error correction and a notably musical, analog-tinged sound character without digital harshness.

Sonically the player delivers an open, transparent and dynamic soundstage with plenty of depth and a very low noise floor. The motorized aluminium tray glides smoothly out after a light touch of the front panel. In addition to the analog signal transfer via the 7-pin DIN cable with full Datalink support for communication with other Bang & Olufsen equipment, the unit is equipped with a digital coaxial output (S/PDIF) for direct connection to an external digital-to-analog converter.
