My uncle was an architect and he designed and had the entire cabined and custom speaker enclosures built while he was living in Japan. Cabinets and enclosures are solid, hand-milled teak. He was meticulous, and I guess what you'd refer to as an audiophile, before there even was such a thing. Although components were added slightly later, the core or the system, including all of the McIntosh components date from 1971. The speakers are based on JBL Olympus 50 S8Rs, with LE15A woofers, PR15 passive radiators, 375 compression drivers, and 075 bullet tweeters. Sensitivity probably around 95 db, so you could drive even with a SET amp. The turntable is a Thorens TD124 Mark II turntable on a custom, isolated plinth with SME 3009 tonearm and Audio Technica cartride, Nakamichi Tri-Tracer cassette deck, and Teac reel to reel. I also have the original blueprints that he created for the entire system-- getting them mounted and framed.
