Regarding haloing, do you suppose a cable impedance mismatch could be affecting it?

Didn't you say you're using a BNC/RCA adaptor? Would that be an RCA cable with BNC adaptor on the LD end?

I wonder if you'd get any different results using a true 75-Ohm BNC cable with the adaptor on the PC end?

Can you explain how that can possibly make any difference?

Arnie.d,

Im not a big advocate of the whole "the cable makes all the difference" that is so prevalent in the Audiophile community. But in this case it really does. At higher frequencies, cables stop acting like "wires" and more like "waveguides". So if you have some high frequency component of the signal that is (due to impedance mismatch like DM said) bouncing back and fourth between the mismatched impedance ends, you will set up standing waves and have the same signal arriving multiple times.

Give it a shot. Can't hurt right? Might even want to clean off some of the corrosion on the jack with a metal polish of some sort.
