Power supply for ethernet switch?

@fastfreight thank you for the recommendations. Unfortunately the switches you mention are too rich for my blood at this point…was trying to keep it under 1K, even less actually.

@audphile1  I actually do need a switch. That’s what’s driven me down this rabbit hole as I have now read so much about them and how some say it can make a difference. So I figured if I’m going to get one and that it can make a difference with an outboard power supply, etc, I figured why not look a bit deeper…

I’ve been back and forth with Andrew from Small Green Computer and he’s been great! So responsive. According to him the Optical Module is the piece that will make the biggest difference. 
 

Thanks to All for your time and advice. Still debating which path to go😬

Denafrips IRIS + Pontus II + TP Link w/ LPS + fanless mini PC source w LPS, + separate power line from panel w/ true earth ground streaming Qobuz; each piece made a difference. IRIS + Pontus biggest improvement followed by separate power line.  LHY LPS relative inexpensive tweak. All worth it w resolving system. 

@trivema COMPLETELY agree about adding DDC to Pontus! I had a rough go of it getting off the ground (having some static issues and a bit of a rough go getting the combo with I2S nailed down), but once everything got straightened out I was floored! Adding Hermes to Pontus was probably every bit as big a jump as adding Pontus to my system. Never expected that big a difference...And thank you for sharing your experience. My system is definitely revealing enough to warrant any tweaks. 

Bottom line for me is I needed to add an ethernet switch anyway, so if there are switches/power supplies, etc that can also make a difference, why not explore that, right?

Hello @kingbr , I do understand.  And some years ago I would have said the exact same thing :)  I do have a suggestion; before buying the fibre conversion stuff, try a Tempus on 30 day trial.  You may be surprised at what you hear!  And, as I found, it is difficult to unhear it!!  Take care, Ken

Thank you @fastfreight. That is exactly my problem though is that once I hear it I can’t unhear it. This is exactly what gets me into trouble🤦🏼‍♂️🔫😂!
