This is true. But if all you want are dynamics, and detail, you can get that from an MP3 player.
It at least would sound more like music than a DI/O.
which is why, ultimately, ya need to audition yerself. i know, (ime), the di/o is as musical as highly respected digital playback, such as the resolution audio cdp's, and the electrocompaniet dacs. quite a bit less expensive, too. and, i know others feel this way as well.
but, others, such as hantra, obviously do not. if hantra isn't using hyperbole here, in stating that mp3 is more musical than the di/o, even if the di/o isn't his cuppa, then i know i can safely disregard anyting he offers in the way of equpment suggestions, as he's obviously deaf!

of course, i believe he *is* using hyperbole here...
in this specific case, i tink dynamics & detail are needed, as the meadowlark kestrals are weak in these areas, imo...
ymmv,
doug s., w/extremely musical sounds emenating from my self-modded art di/o...
