In fact, it really isn't for most people.
Neither is Hi Fi, the vast majority don't give a crap one way or the other.
They'd tell you your nuts for spending big money on stereo.
So don't start thinking you know the way.
If your really into HiFi, the surround market is where the progress is.
As J. Gordon Holt said about 25 years ago,
"With fidelity in stagnation, spatiality was the only area of improvement left." JGH
"As you were so committed to surround, do you feel that the commercial failures of DVD-Audio and SACD could have been avoided? J. Atkinson"
"I doubt it. No audio product has ever succeeded because it was better, only because it was cheaper, smaller, or easier to use. Your generation of music lovers will probably be the last that even think about fidelity." JGH
Maybe if you hadn't cheapened out by dividing your budget between separate Stereo and 5.1 systems and built one really great multich rig you would have felt differently about it.
So along with the many other ASR multich enthusiasts here, I feel in pretty good company with the likes of Gordon Holt, and Floyd Toole.
