Just, that for ultimate performance systems do vary in presentation.
What do you think?
I think yes of course they do. But not because they should, but because they fall short.
There's every bit as much need for extension, dynamics, and thunderous bass with classical orchestra as with rock, rap, or electronica. At least if we're serious about "ultimate performance."
Which I think we are not. What I think we are talking about instead are making intelligent trade-offs. Then yes of course the guy who listens to chamber music, folk music, whatever like that, will be smart to trade off high volume earth shaking bass for believable natural midrange and imaging.
But don't kid yourself. There is tremendous dynamic energy in even solo violin. Come over and hear for yourself. Just because all we have is Doug MacLeod on guitar doesn't mean when he taps his foot or slaps the guitar body its not making bass you have to experience the feel of to believe it. Yes you can get by just fine without it. But man oh man when you have it all, you know it was worth the trouble.
So at least in my view the ultimate performance systems will all sound exactly the same. Because they will sound exactly like whatever was there in the first place. But that's only because that is my definition of ultimate performance. If your definition of ultimate performance is more like what I would call ultimate satisfaction then it could be anything.
