Purchased new as AVR-202. Returned to B&K several years later for upgrade to AVR-212. This provided enhancements for THX Ultra Certified and THX Surround EX for ultra high resolution reproduction of musical details. Unit is in like new condition. It has been well cared for and maintained. Has also been a source of many hours of pleasure and appreciation of the high quality sound reproduction. Sound quality is superb in all modes. Input/output connections are optical digital audio, coaxial digital audio, S-video, composite video, and analog audio.
