What is the Little LOCO MK 2 and who needs it?
The Little LOCO is 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 my realization of this approach. From the first moments of listening, the musicality is stunning—spacious, effortless & full.


NEW Mk2–good to go. 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.

I must tell you. I thought my system was emotional before, but I now realize just how much of that aspect I was missing. This new Little Loco is otherworldly, and I think will do extremely well for you. I am having a hard time finding a record that sounds bad! I mean, really? I just can’t believe it. I have no criticisms and appreciate the art you have done here. Well crafted. Congratulations and thank you!

User Experiences
Sutherland Engineering Little Loco phono preamplifier, by Herb Reichert @ Stereophile, January 2022
The LL works especially well with my 2 Dynavectors: a Te Katora Rua and an XX2-MKII. I must offer my sincerest thanks for this truly remarkable Little Loco. I’m a classical music lover, and believe that the genre makes by far the greatest demands on an audio system. I’ve been through many phono preamps and SUTs, none of which have provided more pleasure than my Little Loco together with the above cartridges.

Hi Chad,
Well the little Loco is up and running and all I can say is WOW!!! I’m hearing notes and decay that I have never heard before. Thanks for your help with this upgrade. I appreciate the quick turnaround and the audio comparison you told me.
I will drop Mr. Sutherland an email later to tell him the same.
Thanks again!
Alan
