there are several that play dvd-a; pioneer,kenwood,panasonic, and sony made one to play sacd, nothing i know of except a computer will play flac directly, avchd is a blu-ray codec and i don't believe there is a 12 volt blu-ray yet, i believe that mkv is also a computer codec, so doubtful that you will ever find any 12 volt audio system to handle those computer codecs, but blu-ray is probably on the way.
