Network Switches

@discopants   I'm surprised that your system is only Spotify premium at 320kbps.  Don't you feel you're leaving a ton of meat on the bone by not upgrading to a hi-res service?  Compared to the money you've put into the switch, gear, power conditioners etc....surely you will hear the biggest sonic sea change moving up to at least CD-quality streaming.

I agree with @three_easy_payments. Subscribing to Tidal HiFi or Qobuz will provide audible benefits vs. Spotify, even if just red book quality. They often do free extended trials for you to try. Currently in US, Qobuz is running a promo $149 annual subscription with one month free trial. Since you already paid $640 for a switch, do the math, the Qobuz sub is no hardship. And not putting down EtherRegen here, as I own one from first batch

Can we allow a fellow time to enjoy the gains he's achieved?  : )

Happy for you, @discopants  

The switch should always be as close has possible to the servers, the server should also be fed through a great LPS as well has the router and anything in the chain should be fed through an lps. for long runs of cable use fiber optic and run the FMC off a LPS.

Another suggestion is to have all switches,lps, fmc's on a good shelf isolated and even dampening plates on top. Also replace those cheap dc cables that come with them with high quality aftermarket dc cables another big jump in sq.
