Article: Reality Quest: Power and Digital Audio with the Sean Jacobs DC4 and Sound Application PGI TT-7 (Part 1 of 2)

I have often wondered how much of the sonic improvement is due to a switch from SMPS to LPS thus reducing high impedance leakage current coming from the PC and how much of the sonic improvement is due to actual improvements to the power supply (noise in the DC current, impedance, etc.) Theoretically, one can test it out by feeding DAVE via Toslink using stock SMPS vs DC4 to compare.

As someone who switched back to Toslink to avoid high impedance leakage current for DAVE, I have to admit it's a bit inconvenient.

So at the end of the day, I think the system we want to have is the system we want to have. So if the DC4 upgrade is superior to the stock SMPS in @ray-dude's system sounds better, that's awesome. And it is great to be able to read about the experience and find out more about DC4. Very neat.
