I'm currently listening to III that I bought used about 15 years ago. (I haven't listened to the remaster yet.) I assume the pressing is from the '70s.
"Out of the Tiles" really suffers from inner groove problems. The highs are so blurry and limited, it sounds like someone downsampled a CD to 22050 hz. Even my MP3 sounds crisper.
Dynamic range was up until the late 90s.
Then someone invented noise shaping, which basically improves dynamic range where the ear is sensitive, and reduces it where the ear isn't as sensitive. See https://en.wikipedia.org/wiki/....
Basically, the tradeoff is that a small amount of high-frequency hiss is added where you can't hear. A CD (or 16-bit Flac) will have dynamic range problems when noise shaping isn't used.
For what it's worth if you're going to buy music online you should probably get it in a lossless format (FLAC) so that if you format-shift it won't result in additional degradation beyond what the lossy codec would normally involve. In practical terms it doesn't matter that much since audio codecs aren't changing terribly often and almost everything is backwards compatible with the older formats, but if you re-encoded your lossy files enough they would eventually sound like garbage.
AAC, when done right, will sound better than CD when created with a 24-bit source. Just make sure to buy without DRM.
Anyway, if you're streaming, should you care? You don't own it anyway.
I use my turntable a couple times a week. It's mostly because I want an excuse to get up from the computer to walk around while I flip the record, and because I like the artwork. New vinyl costs about $30 an album, so I only buy it when I really want it. Vinyl's really a crapshoot for audio quality, though. The modern digital remasters of anything printed before 2000-ish sound better than the original vinyl. A shibata stylus will reproduce the full human frequency range of hearing, although with more surface noise. (Humans can hear up to 28khz, but streaming services will limit it between 15-20khz.)
For streaming, I use either Amazon Prime or Youtube. I still like having my collection of music; but I know its days are numbered.
One thing that I'd like is an audiophile grade streaming service. There's evidence that humans can hear up to 28khz; although lossless 24/96 is overkill.
I occasionally see an ad on Youtube, and I can skip it after watching for 5 seconds. So what do I do? I skip it after 6 seconds. Now I don't have to push buttons!
The well-designed ads get their message across in 6 seconds, but the bad ads assume that they have my undivided attention and are still going through some artsy-fartsy fade-in when I hit skip. Good riddance to the long ads!
Seems like this is really going to impact the advertisers more than the viewers. "You can no longer treat viewers like a captive audience, you have to get your message across in 6 seconds" is an important message to make to advertisers.
If this is timesharing, give me my share right now.
