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.

Great Review. Thanks!

Certainly The Duo is an incredible product.

My whole analogue system sounds better, my Soundsmith cartridge, my Nottingham turntable, my Origin Live tonearm, all have better affinity with my ML No.326S preamp. Now it is more transparent, with a balanced tonality, airy and extended, open and so smooth. Better!
