Re: [ARSCLIST] Early stereo LPs: subject to mononuclearosis?

Hi, Tom,

No, I don't think the centre speaker is sympathetically vibrating. I 
just look at it and it seems as if the sound is coming out of it. 
BUT, when I click and move the signal to it, it the program sounds 
rather different. As I said, some of it is room, but most of it is 
head geometry. I think if I rotate my head so one ear is directly on 
axis to the active speaker, the difference is less, but I haven't 
played with it too much.

Cheers,

Richard
