--- "So I did buy one of these from Chad and it has been in my system since Tuesday. If you have a 20/20 this is a must have over the two stock power supplies that it came with.
It gave the music a more "you are there" feeling and does add additional detail to the music that I was not hearing previously.
When you think about the cost it is only an additional 18-23% (uncased or cased) over the initial cost of the 20/20. So I think it is an excellent investment for the return that you get.
Highly recommended!! - Tom L. 3/22/19
We are offering this Dual Linear 48vdc power supply for the Sutherland Engineering 20/20 designed exclusively for us by Ron Sutherland himself. See sutherlandphd.com for all the details.
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 dual 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 stock 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. 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.
The unit includes Black powder coated steel chassis, 2 - 6ft DC cables and 1 - 5ft AC cable attached with strain relief. Just remove the 20/20 cover and old cables, plug in the new ones and you're ready to go.
How do I get one?
The 20/20 Dual Linear Power Supply with chassis is available for purchase now at $500 including CONUS Shipping. We prefer Paypal as it's a safe, quick and easy way to get your information and payment to us.
We also sell just the board without the case for $400 if you want to fit your own.
