Rush Permanent Waves 40th Anniversary

Why do you think that?  
The marketing info for it says it was taken from the 2015 remaster. 
It doesn't say its source.
However, I have several records remastered from digital files that sound pretty damn good.  I dare say, when done well, most folks would never be able to hear a difference.  
To my ears, this reissue sounds a bit muddy and lacks depth.  Even the bonus Live LP has far inferior SQ to a much older album, All The World's a Stage.
I wish I could return this to the shop I bought it from.  

I will give mine another spin to see if maybe my mood affected my impressions of this.  It's possible I got a bad copy.  It doesn't sound terrible FWIW, just not as spectacular as it should IMO.

I played it again last night and enjoyed it much more than the first listen.
I can't explain the difference.  A combination of mood, electrical noise, groove break in?  Not sure, but it sounds a lot better to me now.  Turning it up loud could have helped as well.
