“None of these options would break the bank”
@rivinyl
If you haven’t already, upgrade the wall-wart power supply of your Trendnet switch, something like the iFi SilentPower iPower2 for a noticeable impact.
In my experience, LAN silencer-type devices don’t do much. I’d recommend saving that money and putting it toward a Network Acoustics ENO or ENO2 passive filter upstream of your EDM MKII. Those bring genuine gains in clarity and ease without adding artificial smoothness. ENO2 comes with money back guarantee, send it back if you don’t hear noticeable improvement. I might add, around $1K, the ENO is probably the best tweak you can try out.
BTW, how do you like your EDM MKII? I am looking for one box solution for my 2nd system…it’s native compatibility with JPLAY app make it even more appealing.
