make sure you get at least a 45 X card if your gonna do 24 bit. I recently purchased a 100X 4 gig card for 130 bux shipped that works fine in the microtrack at 24/96. My ultraII also will do 24/96 with no probs. Remember, different cards work differently in different units, ie...what works in one of the marantz units may not work in the MT and vice versa...
