network switches and cables.

@marco1 I'm  running two computer setup in bridged mode via Euphony operating system on a custom build streamer. this being used as the server only, Streamer is Sonore OpticalRendu, so this fiber conversion post server. I have both modem and gaming router installed close to audio system, 1/2m Audioquest Vodka ethernet cable modem to router, both router and modem on outboard lps. Router feeds the custom server through JCAT NetXE, this optimizes/isolates ethernet. Wifi also disabled on this router so no issue with high levels of RFI on audio side of network, this I label as 'clean' side of network. From this router I daisy chain a second router located elsewhere in house, this provides wifi for house. So my audio system router minimizes noise via disabled wifi and external lps, gaming router chosen for fast speed, low latency. low latency/high speed good as signal in noisy environment (router0 for minimal duration.

Adding an audiophile switch proved to be redundant in this case since router is relatively clean via above measures. All adding the switch did was add two more ethernet cables and another quality AC cable. Renolabs Ultimate was the switch in question, pretty high quality switch. Don't mean to cast dispersions on this particular switch , may be helpful in the usual setup where modems and routers located far from audio system. Locating modems and routers far from audio system  means long ethernet cables, most running wifi off this router likely no lps running off dirty whole house AC. Forgot to mention both my modem and router powered by lps connected to my power conditioner on dedicated AC line. Result of the usual setup means relatively high levels of noise, means loss  of transparency/resolution, the audiophile switch mitigates this to some degree, issue is you can't get back what you lost via noisy signal path prior to switch. Audio system network needs to be optimized along the entire path, let the noise be offloaded to rest of home network.

My original set up was Innuos Zen MK 3 to Denafrips Terminator 2, which sounded quite good, connected by Pinetree Audio USB cable. I have since added as follows:  SmoothLAN Network Filter>ZenM3>Pinetree USB cable to LAIV uDDC>I2s cable Wireworld Sphere 48>T2. The uplift in sound has been remarkable, see my reviews/user opinion on Audiogon regarding the addition of these two units. Cleaning up the incoming signal has made a big difference for me, my system is revealing so that must help me in hearing the benefits. Enjoy the music and the journey.

Thanks again everyone for your contributions.  As the saying goes, until you try it in your own system, you’ll not know what differences might await you.  I think I’ll do a switch with a new “good” network cable between the switch and my streamer.  Based on some of the feedback here, and the response from Network Acoustic and other things I’ve read, it seems to be a good starting point.  Whether I’ll need to add a filter will be a decision I’ll tackle down the road.  I failed to mention that I had previously removed a ifi Lan ipurifier pro, which since upgrading to the Pulsar, seemed to inject noise into the playback, rather than clean it up as it did with the Aurender streamer I used before the Pulsar. Maybe I’ll try the ifi filter again after the switch but seems like it might serve me better in my 2nd system where my streaming components probably need the help.

I’ve researched audiophile switches and settled on Network Acoustics Muon and their Ethernet filter. Seems many have tried and failed using less expensive switch solutions.  

@kennyc Network Acoustics seems to be one of the more respected brands.  You mention the Muon and Ethernet filter.  Did you mean NA switch and Muon filter? If yes, did you try other switches before NA and how did they perform?
