CX-1
CX-2
(1992 - 1997)

After the gain in size and multiple functions of its preamps throughout the 1980s (CX-1000, CX-10000), Yamaha went slim-line again with two versions of the same preamp: strictly audio (CX-1) and conveniently audio-video (CX-2). Both were part of the "ToP-Art" series: Total Purity Audio Reproduction Technology.

The differences in specs between the CX-1 and CX-2 show that the addition of video circuitry in the CX-2 was made at the expense of audio performance...
Anyway - pretty rare, perhaps due to a fairly uninviting design, but the CX-1 is Yamaha's last strictly 2-channel audio preamp and still very much worthwhile.
