Currently, I'm using PoE from that closet to power my Cisco switch, but I've been told to avoid PoE because it can negatively effect SQ. Not sure if that is true, but would appreciate thoughts.

 

Don't worry, PoE to power the switch works just fine as long as you don't use wrong type (shielded) of cables to connect your audio devices. Network signals between switch and devices are transformer isolated. Shielded cables would connect grounds together and create possibility for all kinds of dirty leakage currents. One of the points of using ethernet for audio is that it allows isolation for example USB doesn't. So only use standard UTP cables!

 

I also power some of my switches and all wireless access points over PoE.

 

 

All built in PSUs of switches are SMPS for efficiency, size and heat reasons.
