It's really incorrect to say the name meant nothing. The sonic holography circuit is first patented, which means it has to do something. What it actually does is send a little of the left channel signal to the right channel, but 180 degrees out of phase. It also adds a little of the right channel to the left channel but 180 degrees out of phase. In this way, it helps to couple the left speaker to the left ear, the right speaker to the right ear, and the out of phase signals make that happen. Impressive on the right recordings, awful on gimmicky recordings. The C-6 preamp will work with any amplifier.
