>How can Ifi's dacs support 32-bit audio?
this is what iFi said in response to this on headfi.
>It was the result of excellent work done at Burr-Brown Japan before it became TI and was meant to be used in High End universal disk players with excellent performance for CD replay, Audio-DVD and SACD. Unlike most newer Chips from TI and many others, it retains a true multibit core for PCM replay, based on the visionary (and under-appreciated) PCM69 AND it retains Burr-Brown’s unique and excellent approach to DSD replay, first introduced with the DSD1700 Chip.
>What this means in practice is that the DSD Stream only passes an analogue lowpass filter, there is no up-conversion or data manipulation applied at all. Very few DAC Chips available today allow for this.
>Further, with this chip we retain a true Multibit PCM Core, true, only the upper 6 Bits are converted using multibit conversion, while anything below the top 6 Bits goes through a 256FS low order delta sigma modulator, in many ways this particular configuration is the best arrangement currently available, short of using a true 32 Bit Multibit DAC, which realistically speaking does not exist (yet).
