I did some quick listening tests and the difference is night and day. I really wasn't expecting to be able to hear a substantial difference but, man, am I happy with the results so far. I was having some problems mixing a particular song of a local band. The problem stemming from the fact that the bass player uses a Big Muff fuzz pedal on this particular song and this caused the bass and distorted guitar to meld into a sort of uni-instrument. This works great when they play the same notes at the same time but when they each go their seperate ways into counterpoint, the guitar would become muddy and undefined and the bass would wander around the stereo spread coming in and out at different levels. It was very difficult to tell whether this was due to the recording, the room or the instruments. After just a few minutes I was able to get the sounds seperated and tamed! Obviously I'm not done with the mix but the point is I couldn't even get close before.

Here are some pics. I'll be doing measurements soon.
