I've never had the 888 go into another mode once it's running in stand alone D to A. I've only had to turn it of and on again when I wasn't feeding it AES at startup. It doesn't seem to fail after that.

As for the circuit difference I don't remember the specifics - This was probably two years ago that we started using this configuration - and I got the idea by browsing through audio user-group threads (probably 'gearslutz' or one of those) and I distinctly recall someone trying to make their old Avid 888 work - and wasted a lot of time doing that. Given that the 888/24 is so cheap on Ebay, it's not worth the trouble to try to get the Avid 888 to work.
