check your busses and faders in live--make sure everything is set flat to 0.0 dB. definitely try the 24 bit 48 thang, and turning on high quality in the preferences menu. try bypassing the behringer mixer. is the emi thing usb?--by all acounts usb audio is not as good as firewire or pcmcia. what are the things your hearing that are different--are there certainly frequency ranges that are not as defined, or distortion, what does it sound like? does recording the same stuff into another software program produce results better than Live??? If you don't have another app., maybe download a demo of something like Peak (mac) or Acid (pc) and see if recording the same thing into it sounds better than into Live--this way you could at least start to isolate and find the problem--mixer?, emi?, software?!? I've used a number of software programs, and the quality of sound in Live with everything set properly is as good as any to my ears, and the interface blows the pants off all the "competition".
