Neither Mc nor Benchmark serve these needs except on the fringes.
Speaking of fringes, I met Bob Weir of the Grateful Dead back in the 1980s when he was considering installing a solar domestic hot water system for his home. At the time, I had a couple of Grateful Dead albums, had seen them live a few times, and enjoyed their music, but I was not a part of the fanatical "Dead-head" crowd in the Bay Area. (Most of those die-hard fans would have swooned for an opportunity like mine to meet Bob in person at his home!) His house was very nice and upscale - but rustic - and was located in a grove of tall redwoods high above the town of Mill Valley - and there just was not enough hours of direct sunlight for a solar system.
I arrived on time for a morning appointment, and I was greeted at the door by his "butler" (??), who offered me a glass of juice while I waited for Bob to finish his shower. I remember the kitchen/great room opening to the garden and redwood grove via a wood and glass sliding door that was big as a barn door. Bob at the time looked like a 1980's typical straight, clean-cut guy with a pleasant smile, and a friendly and intelligent demeanor. I had already determined that solar would not work at his home, and we talked about that.
Like all good in-home salesmen, before "getting down to business", I had delivered some honest complements about things he obviously took pride in, which was very easy to do in that beautiful setting. So our "business" was quickly completed, and then he offered me a tour of his personal recording studio in a building next to the house. He noticed my white Mazda RX4 GTR, a modified rotary -engined coupe with its black rocker panel strip with the letters "GT-R" and a flat-black painted hood. He showed me his BMW 2002Tii as we talked about the joys of driving small, stick-shift sports cars around the hills of Marin County and the Bay Area. That meeting was a very pleasant and memorable experience with a celebrity who was really down-to-earth, and with whom I shared a few interests.
But I digress - here are some pics and a video about the Grateful Dead and McIntosh audio hardware...and a photo of some of the cabling used in pro applications.
