Rush 180g re-issue and sonics

'Sup?

My copies of the re-issue of Grace Under Pressure and Signals arrived a few weeks ago and I was stoked to play them fresh. The re-issue of Presto sounded quite good - tho with that album, sounding thin is part of the territory. My equipment is:

VPI HW-19 Mk 4 with SAMA
Benz Micro Ace SE
Sumiko FT3 arm

I was expecting to be blown away by the re-issues. Instead, I was taken aback by their pedestrian and compressed sonics.  For comparison, I played a 1975 pressing of Fly By Night and a 1982 pressing of Signals and their sonics and presentations were wide open and had depth and presence.

I was looking forward to collecting the entire 80's run of studio albums but now I'll just stick to finding the best original pressings of those releases. Anyone have any ideas on why the new pressings sounded worse?
