I clearly stated the advantage or benefit of providing clean AC via my dedicated lines and power conditioning to both modem and router. The greatest benefit for diminishing router noise is the disabling of wifi. As for self generated noise, minus rfi leakage into other components having modem and router far away doesn't somehow magically decrease noise on streaming chain, router does what it does. The improvements and/or advantages of powering these components via clean AC is the same as it is for all the other components and devices we power with clean AC from dedicated lines and power conditioners. The other advantage is short LAN cables and//or less or no need for optical conversion. I also power the router and modem lps with quality dc and ac cables. no cheap outs here.
To argue against the above points means providing clean AC to modems and routers is of no consequence, having short runs of quality LAN cable is no better than long run of inferior cable. Wifi contamination of the router itself and closely situated modem is of no consequence, and yet at the same time wifi contamination is of great consequence when it sits close to other components. Does it not also matter for the router itself and modem?
I'll also add these optimizations are incremental improvements, streamers and dacs are by far the most important components in any streaming setup. The most important thing when addressing incremental improvements is while each on it's own may not be noticeable, adding these improvements in multiples is what makes all the difference. I've instituted these improvements pretty much as a single variable and through long term listening have a pretty good handle on what each optimization brought to the table.
