I'm presuming that you want a recommendation for a replacement power supply?
Having the brand and model of the DAC would be helpful. Or the required voltage at the very least.
I recently got a 12VDC linear power supply to replace the wall-warts for my DSP-408 and AC Infinity fans.
And I have ordered this from the big shopping site : WL-DP01 50VA Ultra-Low Noise Linear PSU to replace the supplies that came with my Schitt Modi 3 and Topping E50 II.

The one I ordered is a 5VDC supply.
I have not received or tried it out yet so I can't really comment on "better".
I have a couple of linear, regulated power supplies from Jameco. I'm not sure if they are anything special and I've not looked at the output on the oscilloscope. They just work. Linear, regulated supplies can get pricey from here.
You will also need to know what your current rating or watts rating is to properly size the supply.

Allo has three different supplies that are 5V at ~3 amps.
Watch this (skip to the 7:45 time to avoid the long intro):
Although you didn't provide a link, I think what you're referring to is a power supply based on the Studer 900 circuit, of which there are several variations available.
This circuit is well regarded over on the diyaudio forum, and a number of forum members use it with DACs and preamps.

Here is the link. I will order and see if it is any good. It has to be much better than those stupid SMPS 5 volt adapter that comes with DAC/Streamer.
In the comments section of that AliExpress listing I saw that a cable was included ... but that cable is likely to be 2-pin circular plug TO DC barrel connector.
You need 2-pin circular plug TO USB-C plug, and I doubt there's an off-the-shelf example of this.
Yes, get a USB-C cable, cut one end off to expose the 5V +ve wire and GND wire, then buy a 2-pin circular plug -
and solder together.

I will do this
The items that I liked about the Allo linear supply was plug and play with the cable adapters and warranty. Does this unit have any merit?
I have a couple of linear supplies on the shelf acquired at surplus value. Those are made by Lambda. Could be garbage or could be another way to a good supply? Anyone have experience with these?
