If I had the dosh, this would be the phono preamp to own!

Really great to hear your observations and comparisons were very lucid and communicative.

I thoroughly enjoyed your review and concise description of the Sutherland Duo. I am leaning towards purchasing one, but my dealer is nudging me towards the Gold Note 10. Can you comment on the Gold Note?

I currently own the Zesto Audio 1.2 but I am finding a bit too much tube noise when I feed it through my Prima Luna HP Integrated.

I appreciate any suggestions you may have.

Do you ground the turntable to both of the DUO's or just one?

I recently upgraded my Sutherland 20/20 to the DUO LPS.
Please update your review of the DUO ASAP, you won’t be sorry.
