Andrew. you are correct in wanting the best clean sound that you can get from the unit. I read a post on another forum where someone wanted a digital in and did a quick search and found that.

But thinking about it more, I would rather have a product that does the 1 thing it was really designed to do very well, than trying to make it into a does everything box but will end up doing it all half assed.
