Power supply for ethernet switch?

Hello @mclinnguy , great question.

I bought the M12 and Optimo a few years ago.  Later, NA came out with the Tempus and I had talked with Rich at NA about it, so I wanted to try it.  I bought it with a 30 day trial.  I think they are very comparable, but I did like the looks and fit and finish of the Tempus better.  The M12 looks (it is) more industrial.  But I could return the Tempus and not the JCAT, so that is what I did.  About the same time, I heard the DeJitterit switch at Cap Audiofest and thought GTT's  room sounded quieter and smoother than most all other rooms.  So Bill sent me one to demo, and I think the Dejitterit from GTT is the best.  It is more than a switch, it creates a 'clean network' for only your audio stuff.  It is an interesting read, as Chris at DeJitterit points out all the other crap in your home makes noise on the network.  Phones, TV's, smart things, lots of things.  So taking all that off and creating an audio only clean network seems to me to be critical.  Taiko does this.  I bought the Dejitterit and kept the JCAT.  So now I have: Verizon Modem > (audio feed only) > JCAT M12 w Sean Jacobs Power supply > DeJitterit switch (has its own power supply) > Audio Only.

All the TV and wifi stuff come off the Verizon modem separately.  My digital now sounds pretty amazing.

@fastfreight Great thanks! Read great things about the Tempus, but never heard of the Dejitterit. 

@kingbr do you require a switch? Are you splitting Ethernet? Or are you counting on the switch to improve something? If it’s the latter you’re going to be wasting your money. 

I love the Pardo linear supplies, i mostly pick them up used… I have my Netgear high performance switch on it, i try to banish wall warts or at minimum get the plugged into a Furman 15 i.

I do convert to optical also… 

@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😬
