Among the earlier Tull Remastered CDs, IMHO SOUND-WISE only:
Stand Up is great; Benefit not so good, LPs are better; Aqualung never has sounded good in any format I've ever heard, Thick as a Brick is quite good, Passion Play is much better than the original LP; Minstrel is quite good, War Child is OK, SFT Wood is good, Heavy Horses is very good. The rest are pretty much all good from there, with Broadsword and the Beast a standout sonically (but perhaps not musically).
Personally I think Heavy Horses is an absolute Tull masterpiece.
Haven't seen any of the concert DVDs, although the "A" CD/DVD set is worth having if only for the live versions of Black Sunday and Aqualung, which just flat out rocks!
Enjoy!
