Concept 16.5 Stereo Receiver

If you know, you know…The typical cliches used are ‘beast’, ‘brute’ and ‘monster’, but beyond hype it’s simply the best sounding receiver I’ve ever owned, and better than most separates I've had. This is not a 70s nostalgia trip; it's a serious piece of gear. The only reason I am selling it is: I have two. It is not far from mint condition. It sounds stunning, musical, crisp and with an authoritative bass that doesn’t drag, due to the overhead of the high power rating. The dual mono makes a difference you can hear- very independent L-R definition that reveals details of individual instruments and a 3-D like soundstage. Virgin, no alterations, as you can see in the clean interior. The only flaws are the AM antenna’s clip has a hairline crack that was repaired and is not noticeable.; and a small divot on the top edge of the face. No missing bulbs or unlit switches, everything lights up. The eq is split 5 ways- bass, mid-bass, mid-treble, treble and a concentric loudness switch which can boost your music into concert level. (see frequencies below) Between all the receivers I've used, the 16.5 has the most you-are-there vibe. The history of Concept gear is easily found online. Created as the house brand to the large Pacific Stereo chain, it was unlike any other in-house gear. Pacific Stereo was also the service center for the big brands. They knew what worked and what failed so they were over-engineered to out-perform the best sellers of the day- Sansui, Pioneer, Yamaha, Marantz., etc. The specs were so much better, Pacific couldn’t publish them for fear of alienating their bread & butter clients. The only high powered receiver with dual mono fully independent dual power supplies; two oversized Dower transformers and four 10,000uF electrolytic capacitors help provide the 16.5 with an awesome power output.All of the outstanding features standard on the Concept line are incorporated in the 16.5, plus some others that are unique. The 16.5 uses a precision 5 gang tuning assembly; and there are two phono inputs with a convenient switch. Individual industrial-grade relays are used to switch the speaker systems.
