System bias

Accuracy can only reveal the realty of what the recording is. If the recording is great, most likely the system will shine. If it sucks, it will probably sound pretty bad too.

The better the system, the more it can accommodate different music genres. 

I’m not so sure. If your a devotee of rock, is the system you put together going to excel in classical as well, or jazz, or folk or country etc.

Nice question. I’ve kind of wondered about this at times. I think the better question is , "Does the owner know how to get the results he wants? I think your question may have been a no in the past with very high end. I have seen the swing from speakers in the 60, 70’s They tried to cater to the mid range and treble and turn down the bass because a bass which is turned down tends to have a better clarity. So with the came speakers which didn’t extend well into the low bass. Then 40/ 50hz Hz is a low enough for bass But it makes the speaker sound good in the mids. So they came up with a subwoofer. So now, instead of tone controls on the preamp you have subs which gives the music something to ride on and grow on, I think I can tune the subs for all the genres. But only to my liking. I think it comes down to matching the subs to the very good mains that have great mids & highs. Then learn how to work the sub to reinforce the mains.

I may have some advantage due to my band membership and being a musician who has also done board work. BTW, I’m not up and down on every song or even album to make adjustments. But sometimes I have an older (mostly)album which I may have to reel in the bass
