Anybody have any? Any A/B tests and sound clips? Im thinking of building one with a couple t15's I still dont know how much of an improvment to expect. I have an maudio dmp3 right now, that goes into my maudio audiophile 192 interface. I use sm57 and cascade fathead to record my amps with... and sometimes drums. I just wish I could hear the difference, then I would know if it was worth the 400 bucks or so... You guys think theres a big difference from a dmp3 to a SCA type pre?
