It is "good to go" with no special concerns on turntable signal wiring.
The original little LOCO had an essentially balanced input signal requirement. The signal came in on both the RCA center pin and the RCA shell. There was a strict requirement that the RCA shell float above ground.
The newly designed Mk2 transimpedance input stage is now single ended. The signal comes in on the RCA center pin. The RCA shell is at ground level.
The transimpedance input stage has been improved. The shell of the RCA input jack is now at ground level. There are now no special requirements or concerns for signal interconnection to the turntable. Glad to say all those awkward and confusing discussions are out of the picture.
Design Philosophy
You may have noticed a new kind of phono preamp design on the market—usually referred to as ‘current input’. Until recently, this approach has been very much in the background. But, listeners and reviewers are now giving it some serious consideration. And many love what they hear.
The Sutherland little LOCO is their realization of this approach. From the first moments of listening, the musicality is stunning—spacious, effortless & full.
System Considerations
The little LOCO Mk2 presents a virtual short as the cartridge load. Instead of voltage being the input parameter, it is the current generated by the cartridge that conveys musical content. The endless worry about finding the ‘best’ load value is obviated.
The cartridge must be the moving coil type. Those with low output will be embraced. Not compatible with moving magnet or moving iron or step-up-transformers.
Thanks to the new little LOCO Mk2 circuit, the shell of the RCA input jack is now at ground. There are no special TT cable requirements.
