I did some thorough A/B listening, comparing the original Number Of The Beast. with the remaster. And the original is better, but only by the slightest margin in my opinion. What struck me was that the quality of the production is very poor. The original sounds very thin - you'd think that a metal album would have a fat and heavy sound. The remaster tries to fatten the sound with compression and EQ but it seems that you can't polish a turd. Neither sound that great to me.
