Apparently, based on the information you just gave, these are indeed the 24-bit remasters. For instance, my Here Comes Louis Smith is labeled as "TOCJ-6594".
I am far from being an audiophile (hell, I like the domestic RVGs just fine), but these sound great to my ears.
This 24-bit remastered TOCJ-6XXX series is quite recent and, as far as I know, generally available.
