The DAC chip in the CSP hardware will turn off its builtin reconstruction filter when fed with 352.8 or 384. The way we plan on doing this for CSP is to use the libsoxr library which is included in squeezelite. I have come up with a set of libsoxr parameters which sound really good when fed to the DAC chip at 352.8 or 384. I have tested this extensively with a USB DAC I built with the exact same DAC circuit as in CSP1 being fed from a wandboard running CSOS. The results are pretty amazing.
