@spiritofradio... regarding the 40th of Permanent Waves, not sure? It sounded great, but unfortunately I no longer have the original pressing. I will say the live records sound very, very good overall. Quite surprised actually. I would say the PW 40th is probably along the lines of Hemispheres 40... to me the H 40th seems a bit tighter and cleaner overall. I prefer it actually. But I don’t like the live records quite as much in the H40 as PW40.
