One thing that intrigues me, and I may be all wrong on understanding the theory, is whether or not it can convert audio at a higher, less-colored standard than the top-end converters, such as Lavry, Weiss and so on, for the following reasons:

According to Korg's white paper on the MR 1000, it uses "State of the art Burr Brown PCM4202's for the AD conversion and then eliminates the decimation filter process and the anti-aliasing filter step which PCM converters go through in the AD stage, and stores the data directly at 1 bit, 5.6448. The filtering of the original 1 bit data stream by PCM converters is what is responsible for the coloration or differences we perceive in converters due to considerations of phase, linearity, transient response and ripple, all subject to the math being done".

If one would go analog line-in, from a high-end signal path, (mic to mic-pre to the MR1000) or from a mix bus, wouldn't you get a truly uncolored, transparent recording with these PCM steps out to the picture, theoretically speaking? Transfer the files to your DAW for editing via USB2. Seems like it would be ideal for capturing stereo for critical acoustic, jazz or classical recording, just using the built-in converters.

Some have mentioned no digital inputs, but what about it's own conversion ability? If it did indeed, convert at a highly tranparent, uncoloured rate it could be very useful for more the ENG, foley and so on. It's got me interested for sure.
