I would love to see a Death boxset with some liner notes and extras, as a tribute to Chuck and his legacy. I would get it in a heartbeat.
But, does his catalog really need remastering? Remastering these days tends to ruin the original work; pushing the peak to the absolute limit, flattening out all dynamic range, and clipping the peak waves to create an overly loud and mushy sound. For example, Megadeth's, Maiden's and Priest's remasters. Criminal butchering of classic records. Death's later records were mastered very, very well, such as Sounds of Perserverance, and don't need to be touched. The early records could use remastering if done well, by an engineer with some discernment and respect for the recordings.
