I know CS-63 are TOTL speakers and they are larger and older brothers of famous CS-99A, another TOTL speakers.
But maybe due to rarity (they were built only one 1970 year) they are not as well-known as 99A. There're also CS-63DX, more common then CS-63.
I got CS-63 as my birthday present to my collection long ago.
Today I finally had time to actually play them, so I moved them from collection room to music room.
I was totally blown away. I expected something maybe above average, but they actually played absolutely gorgeous sound that holds well against few-times-more-expensive speakers (as I always say, market value has nothing to do with sound).
The most surprising was the fact that CS-63 has at least the same efficiency as Klipsch Forte I, and probably even a bit more efficient.
Later I checked specs and I found Forte I is 98 dB (I believe it's too conservative, considering a small Heresy II, made on the same period, is 100).
Pioneer CS-99A = 97 db
Pioneer CS-63DX = 99 dB
I cannot find Pioneer CS-63 specs, but I think they should be about equal to CS-63DX.
For contrast, HPM-100 is only 92.5 dB.
Anyway, I didn't expect Pioneer CS-63 beats Klipsch Forte in efficiency, so I report it here.
When I have more time, I will test CS-63 versus CS-99A and HPM-100; it should be interesting.
