Turntable interconnect

If it's not humming you're OK. But, if you want to ground it you can just run a single ground wire with the IC's you have.

Different from issues associated with grounding, are concerns about shielding in the cables to 'protect' the small phono signal. Some phono cables are designed specifically for that purpose while others are just 'regular' cables with a ground wire attached. Unless the manufacturer specifically mentions it, one can assume (?) the latter.

All interconnects should have a shield. There may be some manufacturers that make a somewhat homemade variety that doesn't but I wouldn't use unshielded IC's.

Sields tend to close in the sound... I use unshielded balanced cable...dead silent.

Sure they do. I figured someone would come up with something like that.
