^ Above, the first 5 DAC's are parallel, multi-bit type (in my experience they have the possibility to sound the best with CD-sourced material). Although the 1543 is a cheaper version of 1451, it still sounds OK (not great). The PCM63 is the absolute best there.
The PCM1780 is a multilevel delta-sigma that has, for that generation, the top three bits (MSB) as multilevel so it sounds a little better than pure delta-sigma - newer TI DAC models are using up to 5 bits for the same reason.
