james.miller, I wasn't talking about lag, but this certainly could be a problem. Likewise losing multichannel would be a problem. Would need testing with the OPs equipment I suppose.
Off topic: I'm very sceptical that you can hear the difference between identical material transported over 16/44.1 compared to 24/192. If you studied music tech you should know better.
If you've passed a double blind test then you literally have superhuman hearing (bat/dolphin level hearing). Anything less is worthless.
I was referring to noticing the difference between 192kbps to cd quality.
So the narky comment about "if you studied music tech you should know better." was uncalled for.
