Sutherland 20/20 - Dual Linear Power Supply

What's wrong with the stock switching power supplies?

We don't think there's anything wrong and neither do the hundreds of 20/20 owners out there.  The standard switching power supply modules have provided quality DC power for years.  A linear supply is much more expensive to make and just didn't lend itself to the original 20/20 design goals. What we do know is that we've had many requests over the years for a linear supply and that in many systems people have found significant improvement from more background silence under high-output conditions to sharper strings and vocal details.  We won't go into what our opinions are because every system is different but will say that this is very solid engineering and these components are used in products costing many times the 20/20's price. This is a genuine Ron Sutherland designed board assembled in the USA and we guarantee it's quality.


--- "After about 15 hours of listening I feel it is actually getting better, all electronics need some burn-in time (-;

I have the original configuration (as designed by Ron Sutherland) with the power cord coming out the back and the two wires that connect to the 20/20 out the front. Chad had told me it his preferred design seeing there is less wire in the signal path even though it is not as "clean" with wire management.

I have mine on a shelf above the 20/20 the two front wires under the power supply then down to the 20/20 underneath the back side and then up in the empty chassis space of the 20/20 and then plug in the left and right jacks

--- "I cannot recommend it enough it has put the 20/20 into another level!! "


---- "Yes it made it more musical, more like you are there...  if you already own a 20/20 this is a small investment in a better music experience" Tom L. 


To Case or Not to Case?

  • Option 1 Bare Bones:  Purchase this unit if you want to save a little money and not have a case at all or if you want to put in your own case. For $50-100 you can find many options. The bottom board protects from any accidental high-voltage contact. The top of the board is low voltage.  Includes 6' IEC ac & dc cables. The board comes completely assembled with red bottom board as seen in the pictures below. If you choose to use your own case and do wiring we can't be responsible for mistakes or performance.


  • Option 2 Gray or Black Steel Case: 12"x8"x2" painted steel chassis. The unit includes 5' AC cable attached with heavy duty strain relief & 6' dc cables all on one end of the chassis.  This change has made the unit more convenient to use in a rack and has less connections with the power cable soldered right to the board.   To hook up just remove the 20/20 cover and old DC cables, plug in the new ones and you're ready to go.  (Thanks to Bob in Arkansas for recommending the Gray color option)  If you want a detachable cord and IEC jack on the chassis it will be an extra charge.
