Oggo´s power supply shoot-out (using the example of an Uptone EtherRegen)

[Blackmorec]

There are those who would say that a power supply should make very little difference to a network data stream. After all bits are bits and these days we have bit perfect transmission. No?

 

No. Because that DC actually is the data stream, at least the voltage part of it, and likely the oscillator is powered by the same supply so oscillator output timing and stability is very much going to depend on the quality of its driving voltage, so its clear that the data stream is simply modulated power supply input. The data stream generates the music that’s played…..the power supplies and all ancillary hardware are responsible for the presentation of that music….so its a lot down to power supplies when it comes to how good the music sounds. 

 

So now comes the interesting part…….power supplies are only part of that presentation….power cables, fuses, DC cables also play a role, as you noted. 

The next place to look for improvements are 

Quality of input mains

Anti-vibration measures such as footers, racks and platforms

Quality of ethernet cables 

Modems and router power supplies and vibration mitigation

Hey Oggo, that was a piece of work! Well done….a lot of your descriptions resonate with what I’ve  heard over the years….very reassuring. And I’ve got a new favorite Gedeutchtes word!  “Gepimped”  Fits beautifully with the practice of tube rolling.
