Ok guys....in a pinch I bought a Behringer ADA8000 today just to have some extra ins until I can afford a nice piece of gear. (I'll use it for a year if it lasts that long). Basically I'm going to be using it for a control room mic, possibly as an A/D when I get better pres, and extra channels for scratch guitar/bass tracks while tracking drums. My question is.....using only your ears....what is the difference in sound between a crappy converter and a great converter? Lack of bass, noise, tinny, etc? I've heard rumors that the converters in this unit are a knock off of the Alesis Al-3....can anyone confirm how crappy the converters are because I haven't had a chance to hook it up. I'm slowly going to start improving the front end of my gear with nice pre's (maybe some seventh circle, JLM, or Sebatron). Do you think that it would horribly degrade the quality by running a high quality pre in to this unit for A/D conversion? Obviously it won't sound like the pre should, but would I be cutting myself off at the knees by doing this?
