No problem Nick, I didn't take you as a 722 snob, but I was wondering if you somehow thought folks were thinking that the microtrack in some way fit the same niche as the 722.
At any rate, I'm not sure this needs to be cutting corners to reach the level of a Sony portable, even at $399. The sony portables were designed awhile ago when this type of audio electronics were not in widespread use -- the ICs and esp very large scale microcontroller integrated circuits it used were not only new to portable audio, they were a somewhat new technology overall and were relatively expensive no matter what the application. The guts of the Sony DAT used very small scale and very precise mechanics and metal work in the transports, and all that R&D and production capability was only used for the small market portable DAT recorders. Compare that to today when A/D codec chips and other ICs that the MT uses are in widespread use and are cheap. The transport has been replaced by a Compact Flash card and associated electronics that have markets in the hundreds of millions of units and are thus incredibly cheap compared to a DAT transport. Plus add to that the fact that the high end mic preamp components (eg op amps) and A/D encoder chips in the days of the Sony portables are now considered old school and out of date. Meaning the bottom line, cheap A/D codec chips of today are better than the expensive, high end ones of 10 years ago (probably more like 12-15 since the D100/M1 was designed). All of which may well enable M-Audio to make a recorder with a front-end as nice as an M1 for half the cost. It may well not be that good, but I think there is room in the price to accomplish it.
