I'm also still getting a feel for mine but have been very pleased. I say fuck the standard configurations. The more I read about microphones and techniques, the more I understand that we are using them in a completely unconventional way. The main issue that I have with standard stereo configs is that they are intended to be used at much closer distances than we are generally allowed to set up. I record at clubs and bars from 20-60 ft back.
Firstly, from limited experience, I don't seem to like the sound of coincident techniques.
On the near-coincident setups, I saw some charts recently that described the required change in included angle and mic spacing relative to recording distance, Well, not really the distance from the source but specifically, the 'recording angle' i.e. how wide the p.a./stage appears to your mic position).
So as you move back from the stage, the recording angle narrows and you can do 2 things to return the balance:
1) increase distance b/w mics
2) narrow the included angle
So you might like something closer to DIN (90 degrees, 30 cm -edit- 20 cm) if you want to stick to a standard technique. I've usually been coming in a little narrower (80 degrees) and 20-25 cm.
What is it that you're not liking? - any samples?
Are you recording in the same venue all the time?
Might be worth heading out one night with the intent of running a few techniques from a few locations in the venue and then evaluate at home. Worked for me!
Now if you're stealthing up close, perhaps the standard configs are where it's at. But you're not likely stealthing 184s unless you got some kinda crazy hat.
