Query: Sound quality leaves much to be desired...

It's a nice looking set. As other reviewers have said it is definitely lacking in artwork. My main issue is that the mix and overall sound is terrible. Yes, it is remastered and LOUDER but so what? Spend a little extra money and get the 2009 Remastered and Deluxe Versions of the individual albums. They are not as LOUD of a mix (why this is considered better is confusing - maybe it's easier than actually taking the time to mix the damn albums) but far superior. The 2009 versions make it sound like you are in the studio with the band. Geezers bass is so warm and alive it's incredible and all the harshness that is annoying about Tony's guitar solos and Bill's cymbals in the Black Box set is removed and you have a much more rounded and better sounding experience. Unless you're a collector of Sabbath (like me) that needs to have everything, avoid this set and get the 2009 Remasters.
