Well I think I very much agree with the above. I have two LPS, a Farad Super3 and a Paul Hynes SR7T double rail. Both have the manufacturer's silver CCs and Shunyata Alpha NR V1 PCs and are connected to a Shunyata Everest. Additionally the Paul Hynes sits on a four foot Center Stage2 0.8. So I certainly agree with what you have expressed.
Things are quite tricky when it comes to routers/modems/switches. Very few LPS are suitable for achieving a top performance level like Farad Super6 or Super10.
In the meantime Network Acoustics has developed a power supply called Origin which is tailored to this specific use case - and is also has a great performance.
