Yes they are 846A's I bought in 1968. They sound pretty good to me. My point originally was that at least for me sight and the mind play almost as big a part in music enjoyment as the quality of the equipment and I was wondering if anyone else was similarly affected. There is a MC-2505 and a MC-275. I bought the 2505 in 1971 and the 275 was a gift from a friend. It belonged to his Dad. One of the reasons the sound isn't as full to begin with is the speakers way too close together. Mine need to be around 10-12' apart to image and produce a full soundstage. If I'm using those words correctly
