My point is just that CD can't offer more than stereo.
So you're looking for multi-channel sound, then? I like multi-channel for some albums, as I've said earlier in the thread (suited to some types of music like Pink Floyd, for example), but ultimately, most live events are up front and center and not with guitars flying in circles around my head (as my Edgar Winters DTS album does). If you really want a more realistic sound field, you could try out some binaural recordings. It depends on how close your head is to the dummy head they used to record with, but it can really make you think you're "there". Good headphones are a must, of course.
I realize most of your comments are about resolution and theory, but claiming Redbook is the answer fails in other ways. Also, I'd love to see a website/database that gives quality reports on CDs vs other formats. For actual audio products, not theoretical tolerances of the media. You seem to be of the opinion that every CD made after some date (1990?) should be great and whatever album you want shouldn't need a higher quality version made.
I suggest you re-read my posts because that's not what I said at all. In fact, I've said quite the opposite, that most mastering jobs have been tailored to the least common denominator and almost totally lack dynamic range these days, which is ridiculous given the digital media they appear on is capable of so much more. Albums have typically cranked up bass response (so they sound better on cheap tinny crap speakers that come with most cars and cheap all-in-one "sound systems" and so they sound utterly ridiculous in some cases on a high-end system with flat bass response. But NONE of these problems has a damn thing to do with red-book audio limitations. Take a good remastered 2-channel SACD that sounds oh-so-wonderful and make your own 16-bit/44.1 resampled version and compare. I think you'll find they sound virtually if not entirely identical. The reason most SACDs (not counting multi-channel) recordings sound so good is they have been mastered with higher end systems in mind. It is my opinion that ALL recordings should be mastered assuming you can play it back on a good system. It should always be the low-end side that should have to crank the bass controls, etc. not the high-end systems having to (and often then have to buy one first as we don't "need" them) adjust an equalizer to "fix" a crappy album so it's not booming bass and tinny highs at us. Certainly, many CDs in the '80s were little more than LP vinyl masters moved straight over to CD. The thing about vinyl is that it has its bass turned down for an EQ curve designed around the limitations of vinyl. If you just move that master over, you get anemic sound on CD (where there is no reverse curve to turn it back up). The problem is then that people blame the CD for the lousy sounding album, but it's the not the format's fault that someone put out a crap product. Today, they tend to do the opposite (crank up bass and highs). Even something that sounds good on CD like Pink Floyd sounded a hell of a lot better when I got hold of the Alan Parsons MASTER instead. It just sound freaking in-the-room REAL. And while it is a multi-channel (quad) recording, it still sounds real if I mix it down to DTS (oh no, lower-bit rates!). The same is true of the SACD version as well (less ping-pongy, but still real). It's the mix that is better, not the format.
But it's certainly not the case. I just bought Imagine Dragons on MP3 because the CD wasn't any better. Worst recording I've heard since Adele's 19. Very sad to have such crappy sound, both have such wonderful writing by the artists. I'd upgrade both in a heartbeat if an upgrade existed.
Yeah, and what you need is a better mastered release, on any format. You can't really fix a bad source at the playback end (well you can get a high quality EQ and only use it in tape loop when it's a necessary evil and "try" to improve the response a bit, but it only goes so far and to do it for every album when they're all mastered differently is a nightmare (better record the end result if it's worth effort). But an EQ is no substitute for the sheer amount of control available on the mastering side from processing effects galore to phase and spatial effects that can't be fixed with EQ (which is band-targeted and can't fix a single instrument already down-mixed with all the other instruments, etc.) It's unreal what you can do to make nice and horrible sounds in something like Logic Pro. I spent a ton of time making my own album sound "Pink Floyd" quality. I think I did pretty well for a first effort. And no, there's no audible difference between my 24/96 master and the CD version or even the AAC version. They all sound identical and I tested them on 6 different systems including my reference ribbon speaker rig that cost me over $5k with bi-amped custom crossovers.
