Hi,
The Pi doesn't have Audio in but if all you want is high quality output
(unbalanced), iqaudio.co.uk do some really nice Pi Hats that use the
internal i2c connector on the Pi (hopefully I've remembered that
connector name).
They did speak with me about balanced audio and the possibility of
making one of their DACs with a TI chip that supported balanced audio
but this is not something that will arrive any time soon.
Theres also these guys:

Either way for inputs and balanced you'll probably not get much
cheaper/better than the EMU 0202 (sadly no longer manufactured). I use
a roland ua-25 (about as old as the EMU) and a Roland duo capture ex
(about as close to a modern EMU 0202 as you can get cheaply).
Please note that the Pi USB bus is shared with the network adapter and a
bunch of other stuff. I don't know if 192khz will be too much for it.

If you're building 1U boxes anyway, might be worth putting a balanced
audio driver chip or transformer in the box. That's what I ended up
doing for a little embedded Pi "codec" I built.
Do you know of any audio chip that would be able to handle 192kHz
sampling on a Pi 2 ? I'm thinking of building IP MPX codecs on raw PCM
between sites. I was thinking using old-fashioned E-MU 0202 for that
job, but maybe there are other solutions ?
Cheers !
