Quality music is no longer expensive to produce; the labels are pocketing the savings rather than passing it to the customer. In lots of 2000 a CD cost about a buck, including professional stamping and packaging. That makes it a couple grand to professionally produce a CD. That's far less than musical instruments cost
You're just accounting for pressing and packaging the disk.
Really good mikes cost a lot of money. Five digits USD is not uncommon. Renting a studio is expensive, and so's building one. THen there's mixing, editing and all that. Talented, skilled engineers cost money, and lots of it.
I'm not rooting for the labels, but props where props are due: "The Labels" know / knew what they were doing. Archiv / Deutsche Gramophone, Atlantic, Telarc, RCA, Columbia, Decca all went out of their way to get better sound. They invented, innovated, adapted new technologies / methods. And that aspect of their business has my support.
Example: Deutsche Gramophone worked with Yamaha to make a recording system capable of getting a 144db dynamic range. That's beyond ridiculous. I have a set of Beethoven Symphonies recorded with this. I had to get a much better amp. The old one couldn't handle it cleanly. When was the last time some indie producer pushed the limits like that?
But of course, if one listens only on crap earbuds or a crap car stereo, then who cares, right? I bet you 9 out of 10 people just flat out don't care about how it sounds, and by extension how your body perceives it. It's more than just your ear holes, you know.
I still think streaming is for suckers. You pay for something that can be arbitrarily taken away by the "content owner" at their whim.
