Pimping your router

Doesn't it just slow the network traffic down to 100mbps, rather than cause the streamer not to work?

For example I would slow down ports on a managed switch from 1Gb/s to 100mb/s, and a 1Gbs streamer would still work.

But this was done at the switch level, perhaps an inline device like what most network filters are will indeed cause problems.

Yet another update: while I originally used the Acoustic Revive RLT1 filter on my streamer and then Etherregen, I have now moved it to the Draytek Vigor 2860 router, i.e. right at the entry point of public ADSL. The resultant clean up of soundstage, insteument timbre, attack and decay is simply unbelievable. Very highly recommended. 

I have a few Waversa EXT-1 LAN filters (inline filters) and have been playing with different positions in the audio/network chain.

But had not tried it yet where you suggested. This is huge. I had no idea the public cable internet line was bringing so much noise into the house. The weird part is my streamer and TV, which both saw improvement doing this, are two network devices away.

Cable Modem > Cisco Router > LHY SW-6 Switch > Streamer/TV/NAS

I put the filter inline between cable modem and Cisco router, the earliest point in the chain possible.

Just realised you were first to suggest using a wired router only, and offboarding a separate wi-fi router if required. Even before @sns suggested it !!

But regarding LPS, I always championed them and found they improved everything non network, but when it comes to switches and routers sometimes its the reverse and the stock SMPS is better.

Maybe I just do not have enough LPS on hand to find the correct one for network gear. In the meantime I found the iFi X and iFi Elite SMPS power supplies work great with network hardware, a step above stock SMPS.
