How many power supply devices do I need?

I find it interesting that you would not spend a few hundred $$$ on an Endpoint/Streamer to isolate your DAC from the Core/Nucleus but you are willing to spend several hundred $$$, or more, for one or more Linear Power Supplies... Good luck...

Just get Teddy Pardo's to replace any wall warts. Most all power values are available.

ddude
so connecting nucleus directly Via usb to dac is not healthy? 

so I need a device between these two components? Which ones make sense.  My wife is away and she left me some blank checks. Thanks.

There is no "isolating". The thing about my humor, once you experience and understand what's going on its the dude's post that's really funny. Seriously. Just plug em in.

ooooohhhhhhhhh.
