If you don't buy the size LPS that is specified by the amp maker you are wasting money. In your case that's 24 volts and 4.5 amps. Only one of the three you linked met that standard.
$100-200 linear power supply
Trying to remove the digital glare from my Fosi Audio TDA7498E amp. Would changing to a linear power supply do the trick? Speakers are similar to Devore O/baby and Micr/O and listen at 70-80dB max.
Open to any suggestions. Would any of these be suitable?

I like this because it uses FRED’s but only 2 amps at 12VDC.
