I used them years ago quite extensively, tried many kinds of cables in widely varied price ranges, wanted to understand the contribution of cables in total system.
Funny, but since that experience I no longer feel undecided about cables. I've either auditioned or owned much more expensive cable than present, but my cable situation has been static for a number of years with present setup of mid priced off the shelf and diy. Know I may not have best, but feel much bigger fish to fry in context of a whole system.
