Good grief, Charlie Brown. There are plenty of people that have done tests beyond the converter differences and now understand that the very "engine" of a DAW can have a "sound" as well as the summing busses, of course. All these different DAW's we've mentioned are pro as soon as you get it in the hands of a pro! ProTools has become the "standand" because they were there when computers were very limited...they got in on the ground floor of the market and thus have the most 3rd party development for their system. It is very accepted that PT has some fundamental flaws in it's design..issues that compromise the audio in certain ways. There are other systems out there that do sound way better...like the sadly forgotten Paris for example. The sound is way more musical and desirable over PT . --poor marketing and business on Ensoniq's part, I guess, or maybe, PT's strong arm in the market...who knows.
