I have a MiniDSP 2x4 Balanced and I am using a very poor quality wall-wart PSU. As far as linear power supplies are concerned, is something like this a huge solution to a small problem?:

I would really like to upgrade the power supply to the best possible but I am sure it doesn't have to be as expensive as that. Can anyone recommend a good product in the UK, please?

This would be better:

I have some kind of small Apple charger for my 4x10 HD , so this one might be an upgrade for me too , - which voltage is preferred ?
I built a Salas L-Adapter Board regulated power supply for mine at 9 volts. Sounds better than the stock one for sure.
I haven't done any other experiments with the MiniDSP.

I bought a Topping P50 PSU to simultaneously power my 2x4 @ 15V, and a Chromecast Audio streamer @ 5V. Not inexpensive and not DIY, but I'm very happy with it.

I have set up my MiniDSP 2x4 with an 18volt battery power supply. Seems to work well. Nice and quiet. Shaved a couple of dB’s off the input and output to reduce the risk of clipping. Early days yet, but a lot of scope in such a little box.
I bought a nice cheap LPS from eBay decent toroidal transformer and it even uses Elna caps, I have some Nichicons and audio note to swap and upgrade, I just use it to EQ and time 3 subs but fancied upgrading and £25 on caps seemed like a worthwhile punt
I have a nanodigi plus four Khadas Toneboard dads running of one of these, seems to do the job well.

Ditto - I've used a 12-18volt batteries (power tool and car) for audio out in the bush.
I use a laptop brick as the power supply at home.
A computer USB port is the only option I tried that was noisy and not OK.
I have Minidsp 4 x 10 and Nanodigi with stock supplys and never felt the need to replace them , i have now added a UPS 2000VA to power the intire setup anyway sounds really good , still i wonder how much better would other supplys sound...
I bought a £70 nice 12v linear power supply from eBay, nicely made and has reasonable quality caps etc
Hi,
I have the same system as you.
All the Khadas have their own 5V power supply. But I have a problem on all the outputs. There is a DC voltage of 1,2V !
If I connect these cards directely with the USB connector the output are 0V, that is correct.
What do you think of that ? What can I do ?

I have 2x4HD and am using the wall wart included in the box. Why would I go to the trouble of using something else?
I would suggest that a 12v SLA is not a good choice - yes, quiet ... but:
a. it needs recharging, and
b. the voltage supplied to the nanoDIGI could be over 13v (when the SLA is fully charged).
I too have a nanoDIGI; I started off using a 12v Sbooster linear PS - then I changed to using the supplied Meanwell SMPS ... but with an isolating transformer plus hash filter between the Meanwell and the wall socket.
