There are Savatage remasters? Where? That's news to me (bad news for my bank account)..
Yeah, the Black Sabbath ones.. I think the Rhino ones are way, way good...... I compared my Black Box with the UK released Legacy Edition stuff that came out (supposedly not authorized by the band, either), and the Black Box ones are the way to go. The Legacy ones certainly sound better than the Castle junk but the quality is not worth the $20+ you'd pay per album.
The new Pink Floyd ones, as far as I can tell, are a money grab in the worst kind of way. I only tested one, 'Meddle', but there was very, very little difference compared to my older remaster. They are a little quiet but they just sound great. I even prefer that older release of 'Dark Side..'. If someone who has these has a better report then I'd be interested in hearing it...but I was not about to spring for another one after 'Meddle' hardly sounds different.. (there's more crowd on 'Fearless', slightly more cymbals on 'One of These Days'.... just for the record).
