Some reviewers have said that the re-mastered Beatles CDs are louder than the originals by a noticeable amount. Is this something that you corrected for in your listening?
again; i've only compared new to 80's CD with Abbey Road. in this example the overall level of gain of the vocals was possibly slightly higher on the new remastered CD, which is really of no real consequence. what i did was level match the vocals. the difference is that while the vocals are quite similar in level, everything else is more alive and dynamic....mostly somewhat louder. but it's way more than that. since there are blacker backgrounds and more separation between musical mines, you simply hear farther into the mix, and things are both more prominent and you hear things that were previously obscure.
i don't want to guess about how these CD's compare to my Lp pressings, but i won't be surprised if they don't get into that level of detail.
so the answer to your question is that yes; they are louder but the main reason is the compressed and homogenized mix of the 80's CD's. if you A/B the old and new you will notice that the vocals are similar in level but everything else seems louder.
i think the degree of diference might be affected by the quality of one's playback system. maybe the 80's CD's were appropriate to the early crap redbook players.
