Network switch necessary if toslink input used?

I have heard so many hypes about network switches (e.g., Sotm snh-10g, Bonn n8, EtherRegen, etc.) that can purify the ethernet signal and better feed the following signal chain from network streamer to dac. It makes sense to me as even if bit-perfect is achieved, ‘noise’ can still pollute the analog signal through copper wires and ground. However, would it still impact my setup?

My signal path is ‘TPlink Wireless access point - ethernet cable - Lumin U1 - toslink cable - DSD Sr.’

We know DSD Sr. is immune to jitter, and the optical Toslink connection is galvanically isolated. Then, can a fancy network switch make sound noticeably better? Many folks are arguing the clock in a network switch can significantly improve SQ, especially with an OCXO clock. I also heard the power supply of the switch can also affect the ethernet signal quality. If jitter doesn’t matter to DSD, what’s the value of having a better clock in a switch?

Any ideas would be appreciated. I know Ted is super busy, but your answer with technical background would be even more appreciated.


I’m with you on this. I run shielded Fry’s Electronics Shielded Cat-6 from my ISP’s Modem into a netgear 8 port switch. From their, several Cat-6 cables are run to my Bluesound Node 2i, my PC (music server/HTPC), and to my Sony UBP-X1000ES. I run DLNA to stream form my PC (Sony relies on Win Media Player) and of course Audirvanna for DSD playback of files form my PC.

I also have separate dedicated AC Power for my Audio Equipment (10AWG stranded) & Video (PC, TV, & ISP Modem).
