Olve One are already shipping to the backers but I think it's worth the wait..All your requirements are met except for the DSD.
you may check some pics here posted by a backer who got his unit
I've just checked it out and it does have some merit - it certainly looks great - BUT it seems to be wireless, which is fine if you have a Wi-Fi set-up but I want to connect the device to my old-fashioned stereo preamp and I can't see how that's possible. I also want to use the portable hard drives I already have which have WAV and FLAC music on them and I can't see how that's possible either. I can probably live without DSD but it would be nice, all the same.
