If a linear supply is working for you then you shouldn't care.Rocinante said:I have had very little noise from JLM, Five Fish, and others including CAPI, and my own haphazard replications that I cloned from various PSU's linear supplies, they all seemed excellent. Despite the all in one and small profile os it that much of a difference?
The only way to know the difference between a linear supply and SMPS is to simply try each and measure it.
But I know for a fact that the SMPS can be completely void of all noise if implemented properly. So linear can only do worse. In particular linear almost always has a little mains hum. It might be a 6 dB bump at -90 dBFS in which case again, you probably shouldn't care.
