I owned Randall Research cables many years ago when they represented the current state of the art. I sold them and switched to Audioquest about 1984 and then in 1986 to Purist (which I still stand by).
The Randall cables are ultra pure copper and have Teflon jackets, no shield at all. They are particularly sensitive to picking up RF and EMI and occasionally induce AM radio programming into moving coil cartridges (assuming you live in a PROBLEM area).
If they work for you, ignore any perception of negative comments by me. They are probably as good as many cables made today for lots more money. If you like the tonal balance (not too bright) and they have no issue with RF and EMI in the part of town you live in, enjoy them and don't worry.
