Question about 48bit fixed-point (in foobar)

I am interested in a question: what sound card(map) supports output 48bit?
In foobar2000 it is possible output 48bit fixed-point.

Not in a theme...By the way asio driver wamirack 24 supports  Int32LSB only.
And if to listen audio cd in 32 fixed-point sounds much better than 16 bit padded to 32bit.
I listen  audio  cd on audio-monitors FOSTEX NF1A.

None. From a sound quality point of view, anything over 24 bit has no sense, since there is no DAC in the world that can achieve true 24-bit performance.

I think it is there just to have all options, but it's not of much use in practice.

Someone correct me if I'm wrong, but I think the only difference here would be the 16-bit dithering (before padding to 32 bit) that doesn't happen on pure 32-bit fixed point. That difference is really small, and should dissapear if you disable dithering. Either there is something that is not working properly in FB2K (could be checked using the diskwriter), or it's the ubiquituous placebo effect playing with your perceptions. I vote for the 2nd. possibility.
