Ethernet switch worthwhile?

If you are using a wall wart for anything, get rid of it. I use a commercial grade switch using an expensive power cord to it, no wall wart. I use this right after the mesh router in my audio room. 
 

I’ve heard so called audiophile music switches at a couple audio shows and I didn’t think those demonstrations were very good at demonstrating any difference 1 of these switches made, a couple of these demos I thought it sounded better without the audiophile switch. I’ve heard much bigger improvements in changing power cables than changing switches.

A few of these switches are your typical netgear cheap switches with a resistor embedded in them, look at some of the reviews.

Also, a reviewer claims the sq is better if you use 2 cheap switches instead of 1 audiophile switch.

Then you have the option of converting Ethernet to fiber then back to Ethernet right before your source component. Fiber gets rid of all the noise. If you have only a couple of sources you need a quieter signal (?), I would use fiber.

Wll go the ifi- lan ipurifier pro for $299 and wow, very happy with results.  More analog sounding with less digital sterile sound. Better overall bass and bringing forward background vocals. Much smoother, cleaner presentation overall. We'll worth the spend. I notice zero sound degradation, only nice improvements.  Very dead silent background.  Highly recommend. 

So after trying the stock ethernet cable that came with the ifi lan ipurifier pro which sounded very good, I did back to back comparisons with my Cardas Clear ethernet cable and suttle but good improvement.  The stock cable had a bit of sibilance and a bit less warmth. When listening to Adele it was more clear and smooth and no sibilance thru the  Cardas. One great track from Jackson Browne- Of Missing Persons I could really discern the girls background vocals more clearly and defined thru the Cardas. Not tremendous improvement,  but enough I like it better. Overall the ifi switch is really worth it and I like the more " analog" like sound closer to the songs when I play them on vinyl. 

Thanks for all the positive replies to my post and Merry Christmas to all! 

Cheers

Good outcome!  Optical isolation with conventional LAN cables is the key for touch more analog presentation. Funny how a simple change in the chain can shift the entire experience. 

@Initm for even more improvement with the ipurifier pro try one of their upgraded power supplies.  The ifi i power improved things a bit more when I used it with my Aurender streamer.  Happy listening and Holidays to you too.
