This is topic that pops up every now and then, but I'd like to have a whole thread that deals exclusively about it. Much to the annoyance and/or delight of CD collectors, CDs get mastered, remastered, re-remastered, etc. I think I spend as much money re-purchasing older CDs as I do getting new music. Some bands/artists whose albums I've re-baught: The Allman Brothers The Dixie Dregs (Capricorn remasters) Van Halen Iron Maiden King Crimson Miles Davis Mahavishnu Orchestra Julian Cannonball Adderley Sonny Rollins Thelonius Monk Jethro Tull Megadeth Black Sabbath And I'm sure there are plenty more. With the jazz stuff, I do hear a significat improvement. With the rock stuff, the mileage varies. Has anyone has any negative experiences, like the remastered CDs being worse than the original releases?
