If JC is refering to excess noise in LDR's then I can get that - when we were working on LDR volume control we were taking every possible measure to reduce noise - every measure showed an audible improvement and that was at line level. In the end I thought it was a pretty good pot - quite clean - but not as clean as a DVC so I dropped them.

So I can see that at MC coil levels this could be a show stopper

Yes, the light to electrons mechanism is subject to different mechanisms for noise in fact it gets quite non-intuitive at times.
