You do not need to spend millions on a charger... get one with a good current delivery and you are well covered.

Just get an official Raspberry Pi power supply and be done with it. They supply the required power at 5.1 V through adequately sized wires.

Highly recommend using linear power supply.
The improvement of sound quality is monumental.

Which one do you recommend?

Sorry, I do not want to make any advertisements here.
Search the Internet for low-noise 5V linear PSU.
If you plan to use just RPi + DAC then 1A will be enough.
However if you want to use Hard Drive for example then 3A is minimum.

Meanwhile, I'd counter that the official Raspberry Pi power supply is best. Look at prices and decide what you are willing to bear.

Robert, low price doesn’t mean something is best. Official RPi PSU (or any charger as well) is a switching mode device, which is very noisy and significantly degrades audio signal. It may be the best if you use your RPi as a computer, but is the worst with audio gear. Try linear psu for yourself, you’ll change your opinion I promise.

Here's another opinion ;-)

When I say "look at the price", I meant that each person should decide if a linear PSU is worth the extra in their case. In my case it isn't, I can't hear a difference, I can't follow any logic that says how it makes a difference. But that's me, you think it is worth it, the OP may also.
