If the Art or Samson add any noise (and I suspect they do) that'll pretty much blow out any "benefit" of going from 16 bit to 24. Not to mention, 16 bit = a dynamic range of nearly 100 dB, which is probably as good or better than most integrated amps...The only thing you may also want to consider is a signal level converter. Standard home electronics output audio in -10dBu (1.25vrms) and the DCX2496 expects a level of +4dBu (21vrms). You can use an Art Cleanbox or a Samson S-convert Box. The DCX will work fine without it, but if I remember reading right, it will only use an equivalent of 16bit instead of 24bit.
