You don’t need a separate ground wire for the cable coming out of a SUT. A fairly low capacitance, shielded, 0.7m (or less) cable works great. Most shielded cables have shield connected to audio ground on ONE side, and this is the side you should hook into the SUT outputs (i.e. use the SUT as a hub for grounding). 90% of the time, I get no hum this way. I also have cables with a separate ground wire, and honestly this just complicates things - usually I end up grounding on the SUT side and leave the phono stage side floating (which ends up being the same scheme). The internally connected shield is cleaner for this scheme, and works great. The Bob’s Devices cables are constructed just right for this - my only complaint there is the Cardas RCAs grip jacks a little too eagerly.
Does Everyone Use 2 Phono Cables with SUT
I just learned a rather expensive lesson from my audio dealer. I always thought I only needed a phono cable from my turntable to my SUT. By adding another phono cable (not interconnect) from the SUT to the phono preamp, I got a nice improvement in “efficiency.” Everything just flows better.
I guess everyone uses 2 phono cables?
