I'm guessing you are familiar with this excellent series of compilations released between 1998 & 2012. You probably know that these are ALL available for download via the "RZ Compilation Database".
I recently came across an updated list of lossless, remastered versions, complete with art and extensive liner notes. If you are interested in acquiring these higher quality copies follow this address to a spreadsheet detailing download links etc. https://www.imagenetz.de/7MSwd There are a few omissions which are explained in the document but it's the best your likely to find.
