I recently went the route of optical isolation, and even went so far as to put them both into one aluminum chassis with the only inputs into the box being the dc line in and the 2 shielded Neutrik CAT6A pass-through connectors and an aluminum power button on the front. I figure if I was going to worry about EMI/RFI interference enough to use optical isolation I may as well try to minimize it further, especially as the back of my stereo shelf is fairly horrendous with wires.
I power both of the TP link FMCs (MC110CS’) with a single ifi iPower 9v (still returnable!) as it has a rated 2 amps which should be more than adequate to cover the 9v 0.6a adapters that came with the TP links (also stated max power of the TP links is 1.52W, so I think those were overkill to begin with)
So I have been looking around at regulated linear power supplies and have really struggled over what to buy and what equipment I should use it on. Most of my equipment that is close to my stereo that currently use wall warts are the Ethernet switch (12v), a Roon ROCK NUC (19v), the FMCs (9v), and a HDMI switch (5v).
So after what feels like ages I found this HDPLEX 200W (link) supply that can actually run all the voltages of the previously stated equipment at the same time.
Has anyone used this LPS? Also, I guess equally important, is it ok to power 4 (5 if you count the FMCs separately) different devices from one unit? It seems like there is pretty good separation between the different voltage outputs and there is lots of power available. I kind of like the idea of cleaning up all the potential EMI/RFI noise from the Ethernet switch onward as there isn’t a whole lot I can do before it.
I could also be over thinking the whole thing…
Thanks in advance, Veneet
(Also, thanks again to all the folks who wrote up how to set up the optical isolation and listed all the needed equipment, that made it really easy!)
