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.  

Hi,
the first Canadian pressing on Anthem with Rays on matrix is the best of all. All the atmosphere of the studio.

FWIW, I don’t recall my MFSL as being a stunner. Will have to revisit.

Interestingly I streamed the 40th anniversary title last week and had the same impression - very digital and compressed sounding.  I expected something better and wondered how the vinyl would sound.

IMO, most of these New anniversary issues are more about marketing hype than quality. All the "previously unreleased" music that is on the on the extra albums was unreleased for a reason. It's not good. This is my experience with Jethro Tull Aqualung that was done about 10 yrs ago. Admittedly I don't own many because I won't pay the exorbitant price they are charging. This is not to say that all remasters are bad. But they are a toss up. As a Skynyrd fan, I'm glad the remastered theirs since most all the originals sound muffled and without any body. But most of their previous unreleased isn't good either. IMO, the only previous unreleased songs are on the Michael Jackson "Bad" album. But there are only 3 songs.
