Can anyone who has access or experience with these boxes please compare/contrast. I realize these are two completely differents beasts. But, here are the items I am interested in: M2000 - hi quality but several years old, 20 bit s/pdif, available second hand for around $600. M-One - current but midline product (low-end for TC), 24 bit s/pdif, available new for about $375. How much of their hi-end sound has trickled down to the M-One? Is the difference in verb quality sufficient to justify the (small) price difference or would it be silly to pass up an M2000 for that price? 20 bit vs 24 bit (I'll be hooking up through s/pdif)? I know it is difficult to give answers to subjective questions. Thanks.
