Personal opinion only and from experience of me only trying my Sonos with optical and coax I prefer the coaxial....
Mine should be revised version as well? Got it in June from Moon Audio.
Any comments on what it does to the sound?
Yes. And I don't think I'm the only one who reported stock not going above 24/96.... (btw this is the stock white short optical toslink to 3.5mm cable pairing with AK240)
if you are using the mini toslink out of a mac, the mac is limited to 24/96 from its optical output
