I have had TeddyPardo, Hdplex, Uptone JS2 and a bunch of no-name aliexpress linear power supplies, for use on my streamers and network gear. The best of them all was the Farad Super 3. Its only 559 euro, so would be price appropriate and a good match for something like the Weiss DAC 204.
But all these are USD RRP under 1k. I do wonder how good those high end LPS can get... its just another hifi rabbit hole I am avoiding going down.
