I also found good ethernet cables (in/out of a ethetregen) better than using optical from a switch or out from the ethetregen. With my gear optical was too sterile.

Room and the other usual factors make up the rest.

Any comments on this: DXE-ISO-PLUS-2 for filtering? 

Question,

I’m using a Netgear Powerline extender that uses your home wiring.  Can I plug the Green Computer Dirty box into the the second Netgear box?

Thanks

Why use a filter? Why would anybody use toslink? Toslink doesn’t support hires files like dsd or MQA. 
I’ve tried the Ethernet to fiber then back again, didn’t do anything toward sq. 
I also tried all the tweaks/gimmicks for usb and that was also a bust. 
Keep it simple, get the best equipment you can afford and you probably won’t need any of these tweaks

@p05129 agreed on good components. Very important!
However, a good filter like the Eno or an internet switch like the EtherREGEN can help improve sound further.
In my system the Network Acoustics Eno helps relax the overall presentation smoothing out the sibilance, opening up the soundstage and that attributes to a more natural presentation. This was the case with the Lumin U1 Mini/Benchmark DAC 3 HGC combo I was running and continues to do so with my current DAC the Bricasti M3 with a built in network player. And the M3 is already a very refined sounding D to A converter. I’m using EERO mesh network and I think it might be injecting noise into the analog signal it feeds via the Ethernet cable. The filter cleans it up a bit making the job of the network player/renderer slightly easier.

At least that’s the explanation that makes sense to me.

@lalitk my DAC upgrade materialized!
