The DAC in the Node is far newer than the one in the MX, and I'm given to understand from a number of recent forum posts here that the new DACs are so much better that there some question as to whether anything greater than 44.1 kHz Red Book is even necessary anymore.
Another thought is that the MX DAC is optimized for surround sound rather than 2 channel. That doesn't prevent the DAC in my old MAC-3 from performing pretty well, but it's clearly not as good as the much newer, solely 2 channel unit in my C50.
I'd suggest that if the analog out from the Node makes you happy, save your money to buy more of whatever floats your boat. If you still want to try it anyway. buy a cheapie digital coax cable from wherever.
Good luck & happy listening!
