I do set levels with an SPL meter, and my rear speakers are identical to my front three. I still find the rears need to be boosted 3db or so for this release to sound its best. I really don't have to do that with any other disk I can think of. And if your thought is that a majority on this board don't know how to properly set levels using an SPL meter or otherwise, I very much doubt it.
I disagree. The mono mix is still there and the stereo mix is also available. A new, discrete 5.1 mix would have only been but another version. It wouldn't replace the mono or the stereo, it would have supplanted it. Had the Fab Four had good discrete multichannel technology available to them as a playback medium back when this was recorded, who knows how outlandish the original mix might have been. It was the psychedelic era after all.
I agree with you about the increased clarity. The fidelity is better than I might have hoped for. But a more discrete mix would have only enhanced that.
I am humbled at the # of replies to my original post, including yours.
I want to make sure that my comment about how many people use SPL meters was not limited to members of this forum. Based on my experience on other forums (and in particular the Steve Hoffman one), its pretty clear to me that many posters do not experience surround music with matched speakers, room correction, or balanced multi channel output. These are often posters who routinely deride surround music.
That said, if you have a better experience with the new Sgt Pepper surround mix by boosting the rear channels, terrific. Thats why those controls are available. In my experience, I didnt find a need for this and the new recordings are simply stunning with my system.
As far as the surround mix, Martin could never please everyone. It would be VERY interesting to hear a more adventurous Wilson/Scheiner type mix, but I speculate that Martin's bosses (McCartney and Starkey) would have pushed back, and a ton of people would have screamed "sacrilege" ! You made a very good point noting that those who would proclaim it a sacrilege are die hard anti surround critics!
