Has anyone been able to compare the PI2AES against the allo digione signature?
My DAC is an Audio note 2.1x signature so will accept either AES or Coax, so I can go with either solution, I was just interested in which one gives the best sound quality.
Hi John,
Perhaps not much help, however, when I had an AN 2.1 Sig DAC I used an Audiophilleo 2 Mk2 into CoAxial and was not disappointed. Great warmth and a sound that I never tired of.
On the AN DAC, the two inputs will sound the same. It’s actually one input switched between the two connectors, with a couple of resistors (one per leg) on the XLR input to raise the impedance.
Thank you for the replies, I always thought that AES would sound better, so than you for the confirmation that they should sound the same.
This is a similar solution to what I have at the moment, I use a v-link. I wanted to mover away from USB as it is noisy. Cheers for the recommendation
Interesting. I guess every system is a little different. I am using USB on 2 of my 4 Pis. Absolutely no HEARABLE noise whatsoever. 
I am very pleased with both Ropieee and HiFiBerryOS.
