I listened to your first sample, and as noted above, it really does not sound particularly good at all. I ran it through a compressor, which at least brought down the vocals relative to the rest of the signal, and the guitar at the end of the clip sounded markedly better. But as people have suggested, you are never going to get a better recording than your mic can produce. I think that you would find a vast improvement with CA or any other small card mics, mounted on glasses or in a hat. Even though there may not have been anyone on the floor for several feet in front of you, the sound level and clarity drop dramatically as you lower the height level down. Just duck down a foot or more at the next show you are at and see what I mean. Height usually means unobstructed space between you and the sound source, which translates into much clearer recordings.
Depending on the club, and how they mix (or don't mix) certain instruments, you have to place your mics accordingly. If all of the guitar is coming out of the stage amps, and your are further back with omnis, you are going to get a muddled sound, particularly when you have the mics attached to you with a tie clip, which in and of itself is blocking some of the sound. Using cards, with a narrower angle (if all the guitar is coming off the stage in particular) should result in a significant improvement.
As already noted, do NOT run your limiter at all, and avoid using the built-in bass roll-off of a deck like the M-10. You can always EQ in post (which is not the sin that certain people make it out to be). It is very difficult, if not impossible to replace completely rolled off and otherwise distorted low end. Finally, 24 bit will do nothing to resolve your crux issue here. The benefit of 24 bit is being able to run at lower levels, assuring that you will not need that limiter, and allowing you to raise the level in post, without increasing the noise floor. If you can, borrow a pair of cards, run them in a hat, and see what happens. I seriously doubt that any of your prior recordings coming out great was due to any "magic" associated with the Micro-crapper.
