In two instances I do use skinny “Radio Shack” cables - one to connect my amp to a sub and one to connect a Bluetooth receiver to the amp. Those are uses where having a lightweight thin cable was preferable.
I forgotten this little vignette from Stereophile until today - enjoy!
"Once I had the [VPI] Traveler set up, all I had to do was to run a pair of interconnects from the 'table's RCA outputs to the
Parasound Zphono•USB phono preamp's inputs. My first choice of interconnect was
Kimber Kable's PBJ, but with the PBJs in place and the volume control of my
NAD C 316BEE integrated amplifier set at a normal listening level, I heard very strong radio-frequency interference. The unshielded PBJ is particularly susceptible to RFI, so I tried Kimber's more expensive, more conventionally shielded Hero interconnect. With the Heros in place, the RFI was less prominent but still far too strong to ignore. I tried XLO's pretty, purple UltraPlus interconnect. No dice. Then I tried AudioQuest's Sidewinder. This reduced RFI to a level I could stand, but I still wasn't
happy.
Finally, I ran a length of cheap RadioShack Megacable speaker wire (catalog #278-1273, $24.99/50') between the Traveler's and the Parasound's ground terminals. Now, with the AudioQuests in place, my system was dead quiet; I did all of my listening with the Sidewinders. Later, for a laugh, I removed the ground cable and tried using RadioShack's stereo patch cables (catalog #42-487, $6.99/3' pair) to connect VPI to Parasound. Worked like a charm. Go figure."
