Linear Power Supply for a DAC

For my Empirical Audio Off-Ramp, I’m using an Astron SL-11A. Made in Irvine, CA. Works great! Far superior to a wall-wart. Some units come with an IEC inlet instead of a captured PC. You can dial in 12dvc precisely by taking off the cover and turning a screw (multi-meter required). Only downside is that you need to make your own pin connector/cable (Radio Shack parts) - very easy to do. Astron was the premier manufacturer of power supplies for CB radios. Easily found on Ebay.

Here’s a smaller unit that does the same thing.

I run a Teddy Pardo for my Naim UnitiServe and it is ridiculous.  So good that the shop I purchased it from got one for themselves.  I would contact Pardo for a consult for your particular unit.

Paul Hynes makes stellar supplies that work VERY well with Chord DAC's.

Thanks for the replies.
steakster, not really interested in a DIY project.

I've been reading the UK audio forums where there is a lot of talk about Chord DACs, and the Teddy Pardo and Paul Hynes are highly rated. Many people are using TeraDak (Chinese) and they get good reviews.
But something I've noticed and don't understand is that DAC owners are using power supplies with specs that do not exactly match the Chord. i.e., they'll use a 12V 0.5A PS on a DAC which requires 2 amps.

There is one PS being sold in the UK specifically for Chord and it is less expensive than the Teddy and highly rated.

My gut tells me to go for the Teddy Pardo even though it's more expensive. The pros...he works with top audio manufacturer's and he makes a PS which matches the specs of my DAC.
