Linear Power Supply for a DAC

I’m looking for a recommendation for a Linear Power Supply for a Chord DAC. There are some units available in the UK, but I’d rather find one here in the USA.
The DAC is the Chord QuteHD DSD Dac and I’m currently using the stock wall-wart.

Power supply specs are: 12v, 1A, 2.1mm connector. The DAC has a grounding post if needed.

I found this Teddy Pardo model, and the specs say power output “up to 2A.” Would this be a good match for my DAC?

Looking for quality, but wouldn’t mind finding something less expensive than the Pardo.

@grannyring ,
Since you use several TeraDaks, is there an advantage to owning a single voltage TeraDak LPS rather than the multiple voltage units? i.e., 5V, 9V, 12V selectable.
Currently I need to power a 5V digital source.

Where does the Oppomod SE unit fit in this conversation?

What power supply specification or other property could one use to tell if one supply is faster than another. I am also looking for a very good linear power supply for my Acoustic Plan Digimaster DAC which uses 4 - EC86 tubes and has a 15V ? 2A DC input.

There is nothing in the specs on most power supplies that will tell you this unfortunately. You have to try them out and compare them.

Do power supplies have different "sound signatures" (if that’s the right term)?

They will cause different sound signatures in different components. Slow reacting supplies will reduce dynamics (slam factor). Supplies that do not have tight regulation will cause smearing and loss of focus. Supplies that do not have good AC line noise rejection will cause noise in the music.

I have gotten positive feedback on the Sbooster supplies.  I believe they are fast reacting.  They are not earth-grounded, but this can be added by using the right cabling.
