Interesting...is that a statement relative to metal...or remasters across the board? I've purchased some of the remastered Beatles and Pink Floyd's remastered Wish You Were Here and they both sound better to me. But, if it's placebo, I have no desire to throw my money away. I think the Beatles remastered stuff which came out with a lot of hoopla a few years ago w/ a decent sound system is quite noticeably better...probably the most dramatic I've heard. Not come to Jesus better....but side by side-clearly better sound.
The MOST important aspect when comparing two masters is level matching. We will have an article about it soon!
