I had a Marantz 2270 that I purchased new in 1970-something. Damn, that thing was beautiful. I liked the horizontal tuning wheel too. When I bought it I over-spent on the 2270 and was using inexpensive speakers, I think Dynacos... I really can't remember... and the combination worked fine. The speakers gave out before the 2270 did. Later, when I switched to ADS speakers, because Jack Renner of Telarc used them to monitor his recordings, the Marantz wasn't up to the task. The 2270 had a measured weakness into 4 ohm loads. The Adcom pre-amp/GFA-545 combination I bought sounded *a lot* better into the ADS speakers, and I sold the 2270. I'm sorry I did; the 2270 would make a nice conversation piece now. I noticed a bar in Portland had one in their vintage sound system, and people occasionally looked at it and pointed.
My brother, always one to one-up me, bought the Marantz 2500. Even though a receiver that huge, hot, and heavy is arguably dumb, it was a tour de force in its day. I wonder if he still has that thing tucked away somewhere...
Hidden in a closet in my house, in a factory box, is my old Marantz 2110 tuner. I don't listen to FM anymore, except for NPR in a car, but I couldn't bring myself to sell the 2110; it's too sexy for words with that all that metal and that oscilloscope staring at you.
The other sexy thing I sold that I now regret was my absolutely mint Crown CX822 7.5/15 tape deck. When 3M stopped making 456 tape I gave in to a friend who wanted it. That deck was cool. I even had a factory walnut case. Sigh.
