Sutherland Engineering


It is a pleasure to introduce the new 20/20 phono preamp. It is AC powered and it is quiet! It starts with separate external AC power modules for each channel, followed by 10 sections of passive RC filtering and finalized with local constant voltage shunt regulation.

It was Mind-Blowing

Hi Ron,

I have been busier at the office than usual and have had a limited amount of time to listen to records, unfortunately. The amazing thing happened only last friday. Up until that point, every record had had the same two-dimensional brightness to the sound. At some point last friday night, I put on Something Else by The Kinks and it was mind-blowing. Unbelievably holographic-sounding, striking image placement and overall, a rich and dynamic sound with loads of texture. Quite a transformation. Very impressed!


Very Enjoyable Phono Preamplifier

Hello Mr. Sutherland,

I picked up a 20/20 just to audition and fell in love. It’s resolution and clarity are a continuing source of complete musical satisfaction. It showed my xxx Special Edition to be quite inferior.

Thank you for a wonderful, very enjoyable phono preamplifier.

Kind Regards,
Jerry S

Hearing My records in a New Light

Hello, I just purchased your 20/20 phono pre. I’m hearing my records in a new light and I am very happy.

I love my new 20/20


Just have to write “wow”. I love my new 20/20. It is married to my VPI classic and Grado statement sonata cartridge and pumped through my AR tube preamp. The sound is bright and crisp without the rough edges. And as stated on the website, “dead quite”. Thanks for such a brilliant design. I am a big fan.


Preamp was a Stellar Performer Even Without the Footers

Hi Ron – Thought you might like to see the 20/20 with the Mapleshade brass footers, on their maple platform. Sonically, this was a real upgrade. The preamp was a stellar performer even without the footers, but this was quite a significant enhancement. I played a London FFRR recording of Solti and the CSO doing Mahler’s 7th over the weekend, a composition that I never really appreciated. It had me pinned to my seat – audiophile craziness at its best. ;<)

Best, David

You Don’t Know What you Don’t Know

There’s an old saying “you don’t know what you don’t know”.

After auditioning the Sutherland 20/20 with some material that I am very familiar with, what I thought was “normal” is certainty not “normal” anymore when the 20/20 is patched into the signal path.

The robust design, dual mono configuration, and lots of high quality discrete components would translate into the expected sharper focus and detail, with less compression/increased dynamic range. Yes, the 20/20 had all of the above. What surprised me at how differently it conveys complex or dynamic information. Or, more appropriately, how little the content changes in texture and detail when the “rush hour effect” takes place. You know about “rush hour”. It’s when traffic increases and too many things are trying to fit thru the “pipe”. Generally, the most aggressive and obnoxious get thru leaving the articulate and delicate elements stuck in traffic, not to be heard from. Not so with the 20/20. Things remain intact regardless of how much complexity in the content. Those “mangled masses” of sound of the “original” that I heard year after year, in system after system, actually don’t sound that way at all. They are distinct sounds in their own spaces with their own unique chord structure and timbre. Audio 101: don’t always believe what you don’t hear. Or, something like that.

The 20/20 had a lightness about it. Never heavy or bloated. But, it never lacked power and authority when summons to do so. The bass was powerful, deep, and controlled. Once again, what I thought the bass “sounded like” with other phono stages was different with the 20/20. Deeper, tighter, more defined and coherent.

If the goal of the 20/20 is to trigger an emotion response, it certainty got one.

Nice job.

All I can say is you have exceeded any expectation I had


Wow…what can I say, thank you so very much for upgrading the shipping. Don’t know what to say other than thank you, but that seems a little like I am under-representing our complete email dialogue over the past few weeks. This is what drew me to your products in the first place, and all I can say is you have exceeded any expectation I had.

One day I hope to shake your hand and thank you for developing some of the finest…and affordable audio products in the world…but also for the person that you are.

Take care,
Russ (& Paula) L

Dead quiet, great sound.


The 20/20 is very, very good indeed. Dead quiet, great sound.


20/20 is breaking in just peachy!


Yes-siree, the 20/20 is breaking in just peachy! I plugged it in yesterday morning and listened to it last night (for quite a while). It sounds great. I’ve got that system playing right now. Tonight I’m going to take it downstairs where we have the PH3D and compare the two.
