DC power supply question

Posted by MylesJ on October 17, 2024 at 18:33:04:
I upgraded several things and now find that the power supply for my intel NUC is the weak point, although not by a lot. My best sound has been with a 55 year old HP linear bench supply which is going to need some work.

My first question is how much better, if any, are current $500 to $1000 linear power supplies compared to my vintage unit? I need 12 to 19 Volts of DC power to the NUC with at least 4 amps.

My second question is does anybody have any experience with either a very high quality SMPS or a SMPS with LDO regulation? I might try something like that but I would need to find it first.
