Ethernet Filters

I have tried a Gigafoil with an LPS and moved on fairly quickly. It was veiled and quickly set aside.

Outside of my front end powered exclusively by a Shunyata Everest with Sigma V2 PCs, my digital source comes into two ‘Nenon’ modified Buffalo GS2018 switches (powered by a Keces LPS connected to the Everest), connected to each other via Fiber. That is the only conscious ‘filtering’ I have. The only other power related item are two Shunyata Altaira grounding units.

Less is more. Why are two switches better then one?

LOL. I hear ya', @crwilli.

If you want to get your learn on about fiber and using dual switches, I would advise doing your own research. Please take the time to read this link - https://audiophilestyle.com/forums/topic/62477-john-swenson-tutoring-paper-considerations-regarding-usage-of-external-reference-clocks-etherregen-and-other-sine-vs-square-impedance-cables—and-a-money-saving-surprise-at-the-end/

This explains one part. The other part asked from another inquiry? I would advise you to check out this thread >>> https://audiophilestyle.com/forums/...wo-daisy-chained-etherregens/#comment-1167269

You are more patient with pedantic BS than I am. Thank you.

Can you link the fundamentals about this theory?

I found this white paper by EtherREGEN engineer and designer, John Swenson to be informative. A key reason that ER has a fiber connectivity option is because low-source impedance leakage current, which is a significant noise factor, cannot pass via optical, because optical doesn't....carry current. See Section 2 of his white paper linked below. This is why using a run of fiber is beneficial for networked audio systems.

Swenson explains it all here: https://cdn.shopify.com/s/files/1/0...enson_EtherREGEN_white_paper.pdf?v=1583429386

Oh, and John worked as a professional EE Ethernet engineer for Broadcom and Cisco during his professional career, so he really knows what he's talking about in the white paper referenced above.

The key point articulated in his white paper are also why Lumin supports fiber optic connectivity in many of their networked audio components, e.g. the P1, X1, and U2, for example. 'Cause Lumin really knows WTF they are doing when it comes to audio component engineering, just as John does.

Cheers.

I use 2 optical Ethernet cables in my room. One to the etherRegen, and another which runs with my log XLR interconnects to the front wall. Besides not carrying possible electrical contamination, fiber optic cables do not have EM radiation that could affect electrical cables.

Another correct and excellent point, Bones.
 
I forgot to mention a couple of items I use that also help in creating important (IME/IMO) moats, along with improving what signal comes in for the least amount of errors.

A Mesh Network system that naturally creates a moat that incoming line noise cannot transfer through, yet still offers a direct connection on the mesh satellite. The signal is different than that of the Wi-Fi bands for dedicated signal purity.

An ER Gen 1 switch - Offers a moat (ADIM) that any additional noise is thwarted from passing through, if configured correctly.

Mutec Ref 10 SE 120, which is a 10Mhz Master clock that is hooked up through the EtherRegen. The Master Clock provides the foundation for perfect signal processing in a digital audio chain. (I found too that it also greatly improved the sound from an Esoteric P2 Transport in my system).

My apologies for forgetting about these earlier but as mentioned in my first post, "IME, the effect is cumulative and the better the components, the more resolving your system is, the more difference the changes one hears is noticed". If these additional devices weren't also important for the cumulative effect they have on your system, I wouldn't have bothered mentioning them. FWIW.

My listening room is fed via fiber. It converts back to ethernet between components. Then to USB and again back to fiber between re-clocking and DAC.
