Power Cables

@ghdprentice great, so what is your theory. Cables at data centers are pretty standard, as you know. So what 6ft of expensive cable would change in the rack operation.

I’ve used Acoustic Zen, Nordost, and Morrow power cables on my components. All three improved the sound noticeably on my Cambridge Audio 851n streamer/DAC and my Oppo 83 which I use for SACD. A more subtle improvement on my Bel Canto PRE5 preamp, and no difference to speak of on my Bel Canto 500M monoblocks. In the end I kept the Morrow MAP3s and sold the others. They may have sounded very very slightly better than the Morrows, but the Morrows are so much easier to snake through my cabinet. My theory is that less sophisticated power supplies in components react more to upgraded power chords. 

@mikhailark what is the point of using servers without analog components somewhere in the chain and nearby?  OK, powered speakers with wifi maybe.  For more traditional systems, there will be analog gear in close proximity to the server (and DAC).  Just saying, servers rarely exist in a digital vacuum, and cables and other potentially noisy boxes are in the neighborhood.

ASR must be down for maintenance today. 

@knownothing - correct. However, the topic is about purely digital system such as streamer without DAC, or a LAN cable “filtering” device. You have network cables running on top of your tube amp? Sure, shielding might help. Power cable for a network switch or a pure digital streamer? Well, its your money.
