jkruta, I tried going mixerless and it just wasn't a happening thing - even though I mix in Pro Tools and only use the DA7 for monitoring. First, it didn't sound as good. But even if I were to get different converters, it was a hassle switching programs to adjust a fader.
Then I managed to turn on the mixerless mixer without my word clock generator on and blew out two tweeters from the digital pssshhh. Yeah I'm a putz, but the DA7 just gives you a word clock error message when that happens.
Going mixerless is appealing, but I've decided that there's a reason for having a mixer - even if it's big and only sits off to my side instead of in between the speakers now. It's just too convenient to give up.
