Modern Hi-Fi: What really happened to the high-end stereo market?
All of this is without even mentioning that given a decent enough file size, the straight up line output from an iPod or Mac laptop sounds measurably closer to the source than any record player or cassette deck ever made, and many reel-to-reel machines, too.
It may rankle some audiophiles to hear it, but 320kbps Spotify stream can very well sound more accurate to the source than 180 gram vinyl, and an HD YouTube video isn’t super far off with an audio bitrate of 192kbps. (It’ll certainly sound closer to the original recording than any cassette tape.)
Speakers just don’t get that much “better” once you reach the high end of the studio market. There’s no question that at the high end of the market, both the little nearfield monitors and the big wall-mounted studio speakers of today are, objectively speaking, “better” at their jobs than the ones from the 70s.
