Basic switch....should I upgrade?

@fredrik222 

I get where you are coming from, but a good streamer will cashe and isolate from the switch… TCPIP will provide replacement packets, basically making up for the switches deficiencies. 

@ghdprentice definitely. What we’re trying to achieve is minimize electrical noise in the analog signal that carries digital information via copper Ethernet. Buffering in streamers helps with the digital part of it while noise is noise. Higher end streamers supposedly deal with both aspects. Also if a streamer has optical input, going over fibre optic cable eliminates electrical noise. But..there’s just no easy way out…

@audphile1 KISS got ‘cha. Thx for the six part test.
@twoleftears The rundown is as follows.
Wall Ethernet into D link switch.
Out of Dlink switch short audio grade ethernet into EtherREGEN & short run to Roon nucleus.

Also into EtherRegen aduio grade Ethernet  cable from clock.

Out of etherRegen fiber optic to streamer.

I have router to D Link switch with RJ45 to optical isolator with fiber converter via fiber optic to fiber converter on EtherRegen input out, via ViaBlue RJ45, into Auralic G2 streamer.  

This is the optical isolator(fiber media converter).

Gigabit Ethernet Multi-Mode LC Fiber Media Converter (SFP SX Transceiver Included), up to 550M, 10/100/1000Base-Tx to 1000Base-SX https://a.co/d/e6VoowN

Since you have an etherregen: get an ocxo clock (AfterDark, Mutec, Cybershaft or other) You can start with a $100 Chinese clock on aliexpress and the upgrade if worthwhile. I also found dxe filters on the ethernet beneficial. Make sure the Etherregen has a strong ground connection from its post.
