Sure, this gives us no measure of sound, for sound is not reducible to any parameter. But it will tell us which of these DACs recreates the waveform closest to the original, i.e. which leaves the fewest fingerprints on what it does. It will not necessarily be the best DAC, of course, because it could be precisely the specific kind of contamination it introduces that for some hidden reason interacts favourably with the particular source and the particular system of playback. But if so, it would be very interesting, for it will be further evidence that fidelity to music is not necessarily fidelity to signal (though of course the RMS measure does not identify *which* part of the signal differs and it may be that the same RMS in different frequency bands (say) is better or worse).
DAC manufacturers must have done this, and it is strange that you do not see anyone saying: our dac costs $1000 yet it injects less error in the waveform than unnamed competitor dac costing $5000...Rerurn to Romy the Cat's Site
