A trend I've started to notice between a few older releases I have is that they sound very low end or even muffled. The ones I have in mind are Rainbow - Long Live Rock 'N' Roll Genesis - Foxtrot I am especially surprised by the Foxtrot album because a German SEBtP which has similar release indicators that I bought at the same time and place sounds much better, as noted on discogs. Genesis - Selling England By The Pound Setup issues are not very likely since I have much more impressive and vibrant sounding records. One possability would be damaged grooves since some high frequencies are crackly and distorted, but is this likely to make whole albums low end? Is there perhaps some common theme here to look out for as to why this occurs? Are they truly supposed to sound like the way I describe it or is it perhaps just a poor mastering of these issues? I would also love recommendations for better releases of these LPs if you have any to suggest.
