I did some spot comparisons of Rob's u/l's of the orig LPs and mp3s I made from the cd reissues. There is a noticeable difference in both cases. On the original s/t LP, the drums sound relatively soft and rather simple; they're not bad, but they could be louder and more powerful. The re-done drums on the reissue are louder and have more punch (the production overall also is heavier), so the reissue sounds pretty good IMO.
The reissue of 'Day of Reckoning' also goes for a heavier production, but this time the re-done drums don't sound as good. They have a sharp, almost hollow sound- especially the snare- which doesn't sound right. Also, the drums on the orig DoR LP don't sound that bad; they're done better on the orig s/t LP. Thus, there was less reason to re-do the DoR drums, and the end result doesn't sound too good relatively speaking.
That's my take on 'em. Thanks to Rob for providing u/ls of the original LPs.
