I am reviving my basement studio. One of the lessons learned from a few years ago is that I never tracked more than 2 channels at any one time, so instead of "lesser" gear with more inputs, I have gone for "better" gear with 2 channels. So far I have replaced my old Mac G4 450 dual processor with a Sweetwater Creative Station PC, my old Digi001 with a Digi003, purchased an A Designs Pacifica dual preamp, and just ordered a UA2-1176 dual compressor. I also purchased a Pearlman TM1 mic (U47 clone) to go with my Shure KSM32 and some 57s and 58s. If what I read about recording gear is accurate, my weakest link is now my converters in the Digi003. Before I consider plunking down even more money for outboard AD/DA, I'd like to get a better sense of what better converters will translate into in my recording efforts. If the difference between converters like Apogee, Lynx, etc. are "subtle" (maybe an extra 2-3% improvement) when compared to using the Digi003 converters, I'd be inclined to spend that money on another mic or another preamp to get a different flavor. Thus my question......what should I expect the audible differences to be with better converters? Are these differences only apparent to those with "golden ears"?
