Ignorance is bliss, as they say. I've never had the chance to A/B converters. I have a MOTU 24i - picked it up on eBAY when I decided to start playing with multitrack recording. I've come a long way since those days, and still have a very long way to go. I know the old 24i doesn't come up on anyone's list of great converters. What I don't know is what it's doing to me. I've heard that an external clock will improve things. I've heard that 96 KHz sampling is a big improvement. Well, actually I haven't heard those things - I've just read them. I'd LIKE to hear them. I'd love to know if my next purchase should be better converters, or preamps, or mics, or ... you know the drill. My software, preamps, microphones have all been through significant changes since I started this biz. The MOTU remains the same.
