Transcoding DSD256 on Melco

[GreenMtnGringo]

I was going to suggest the free Sonore DSD2FLAC utility, but it appears that it tops out at DSD128 on the input side:

The other thing I wanted to mention is that I seem to recall reading some time ago on the PS Audio forum that PS Audio DirectStream DAC designer Ted Smith may have a potential future firmware update in the works that would make the DAC capable of decoding DSD256. You might want to do a search for DSD256 on that forum and see if there are any updates on that front.
