HI Dean- any well made, shielded phono cable (Cardas, Synergistic Research, Shunyata Research, Analysis Plus) will be made the way that Sutherland specifies. BTW - The Little Loco is an EXCELLENT phono stage!
Interconnects that the shield MUST NOT connect to RCA shell, but to isolated ground wire??
I'm trying to understand my Sutherland Little Loco phono preamp (currect flow) RCA recommendations. Regular and Coaxial style interconnects do not work properly with this preamp because of the way they're grounded/shielded. Want to upgrade but not sure what to look for in this type of interconnect, any help will be great... The manual states this:
" The design of the transimpedance gain stage’s input REQUIRES BOTH signal leads from the cartridge’s coil to float with respect to ground. The (+) coil terminal will go to the RCA connector center pin and the (–) coil terminal will go to the RCA’s shell. That is completely in line with convention. Nothing new there. The signal cables from the turntable will almost certainly have a shield to protect the delicate signal from ambient electrical noise/interference. To function properly, that shield should be grounded at either the turntable or phono preamp end. To work with the little LOCO, the shield ground must be made with a separate ground wire to the little LOCO ground screw. The signal input cable for each of the two channels would optimally be a twisted pair for the two coil terminals going to the RCA center pin and shell. Enveloping the twisted pair, would be an electrically isolated shield. This shield MUST NOT connect to the RCA shell, but will go to an isolated ground wire.
There is a requirement that both coil connections float with respect to ground. Turntable grounds and cable shields need to go to a separate ground wire. There must be no direct connection from either coil side to chassis ground."
Im currently using Zu Audio Mission cables that fit this description (https://www.zuaudio.com/cable/mission-rca-mkii-b).
