Optical Network with Devialet

[struts]

Which one do you think is better for audio data transfer between Ubiquiti
Unifi US-8-150W  (20W excluding POE output,silent fanless operation(0.5 dBr), INTERNAL-ONLY! Power adapter)  ,
Edge Router12    (20W power consumption;slient fanless operation;External AC/DC Power Adapter -24V DC) and
EdgeSwitch 10x  (It can be fed with 24 LPS and it supports passive cooling. It also has 2 1GB SFP port)
?

The number of ethernet ports(should be at least 6 for me) and number OF SFP ports(at least 1) ,which all models supports, are enough for me. Two of them supports external power supply; the other one has only INTERNAL power supply. If Unifi US-8-150W supported External power supply(for LPS), I would not think for a minute and choose it. 

But currently I am close to EdgeSwitch 10x for its simplicity, allowing fiber connection and its LPS support.
Note: The audio-related hardware will still be connected to Sotm SNH-10G.

Fair question @CongoFather, and I will defer to @octaviars (who is both knowledgeable and takes power, grounding etc. very seriously) for a considered answer.

My own choice was dictated by the shape of my apartment ("long and narrow") combined with very (18") thick walls. This makes radio planning quite challenging and means that optimum AP placement is essential to achieve good wifi coverage with a minimum number of APs.  This in turn necessitated PoE at both ends of the apartment, and I went with the simple solution of PoE-enabled switches rather than fiddling with injectors.  My bigrig is now "shielded" by an Uptone EtherREGEN switch, so I took the chance that LPS on the main and secondary switches would make little or no difference.  If the EtherREGEN turns out to offer a worthwhile improvement I will also try it out "back-to-front" in front of my Phantoms.
