Basic switch....should I upgrade?

@cakyol Dude.....This is team USA; everyones knows what they are talking about. (Young man you are no better than your father and he was no better than his father. Bet the internet doesn't know that one.) Seriously I have benefited a lot thanks too many.  Hans Beelhuysen says one thing someone else says another. Ok. Yup. It's everywhere. Here the pervasive generosity is tops. 

I just dig learning about this stuff and like many like my gear (a lot of watch and car folks here too I'd wager) and refining and/or just switching it up. Your honors, my room is the weakest link but that a non starter w/ you know who.

@sns Bingo! That mangled blue junk from the modem to the router could use an up grade. While I'm at it will also get power lines away. 

@bd  no, adding to fix a bad link in the chain never works. Remove the crap out of the chain instead. 
 

basically you are saying that using your iPhone DAC and source into another significantly better DAC will fix the issues with the phone DAC. Not possible. 
 

a switch operates on layer 2 in the tcp/ip stack, and will only check for crc frame errors. A switch doesn’t do anything to correct timing (jitter) issues. That is just not how a switch works, period. 

I’ve read lots. Reviews. Audio forums. Watched a few Youtube videos as well.

The people I want to listen to say yes.

I tend to ignore the likes of Cakehole. He says no. Old school. He tells us to stand in the corner.

@antigrunge2  @melm & @audphile1 I did ground the etherREGEN and the PSU to my streamer (both having ground screws) with some scrap 12G wire and I'm surprised how more holographic sound is. It's like my speakers took growth hormones. My holographic cherry has been popped. Thanks gents.

I chucked my poor switch and use only the etherREGEN. As tempting as a Network Acoustics Eno or Moun would be that would require a switch.

If it ain't broke don't fix it.... unless you're an audiophile. Right? 

@sns 

People should concentrate more on feeds directly out of modems. This is most common weak link I see...

I have tried to address the situation.

I have my modem attached to a modded Cisco 2960 switch. Then (Cat5?) ethernet cable running 10m (can't replace this cable unfortunately) to an ethernet outlet. 

Have a Lan isolator connected to the outlet to a modded Cisco SG110D switch, then another Lan isolator connected to streamer.

That may address some of the issues.
