External Linear Power Supplies

Does anyone have any experience in comparing the following external linear power supplies:
SBooster (most expensive)
Small Green Computet
iFi Power Supplies (least expensive) ?

I am interested in effectiveness, and bang for the buck.

I would use one of these to Power a Chord Qutest, a SugarCube SC-2 and a Massdrop THX AAA Headphone amp.

Thanks.

@jerrybj Thanks for the link.  Looks like my current SMPS is 12v 5amp.  Will this be too low on max current at 4amps or is sufficient?

Innuos Pulse Mini.

I'm considering this one https://www.aliexpress.us/item/3256802540609695.html?spm=a2g0o.order_list.order_list_main.5.5a631802RTaupl&gatewayAdapt=glo2usa

Low heat running Nichicon caps.

Some good reviews for the Pulse Mini.

Check some forums to see if a particular voltage input is beneficial i.e. does the Pulse Mini have a voltage sweet spot?

A decent DC cable as well. I have some from Ghent Audio which are good and reasonably priced.

 

If you can afford it, I would buy an LPS that has good reviews.

I love my Plixir Elite and TeddyPardo (and Coherent Systems UK) power supplies.

Like my Teradak DC30 and FiiO LPS.

Okay with the two generic dual supplies from AliExpress.

Read somewhere a guy who liked his PD Creative on a BlueSound.

 

As you know, a good power supply will lift performance, and should be an investment with no regrets.

The one review I had found that used a separate power supply for a Pro-Ject Stream Box S2 Ultra streamer observed no improvement. I reread that review a long time later, and they used the Project Battery power supply.

So you are saying a battery power supply is inferior to electrical linear or switching P-S? Any reason why? I am just trying to learn.
