I enjoy live music more than anything, and there are absolutely quantifiable aspects of reproduction that can make it close resemblance of live performance.
Deviations from live performance can certainly be a preference for some, but such deviations could be called anything but musicality by definition of that word.
In relation to Sasha’s posting, in my view of the world, a set of components should bring you as close to what is on the recording...with the absolute understanding that what’s on the recording will not bear any close resemblance to live music.
To me, chasing the goal of reproducing a live performance is a fool’s errand, but chasing the goal of reproducing what is on the recording isn’t.
Microphones, the first part of the recording chain are not perfect in anyway, where they are placed and how many (i.e. do you multi-mike a drum kit or not?) all change the recorded acoustical space (relative to the live performance) etc etc etc, all the way down the recording chain. And then we have the playback chain.
Producers, recording engineers, mixing engineers, cutting engineers all have their own fetishes about what they want to lay down, so any recording is firstly compromised due to technology limitations then further “distorted” by the artistic bents of those making the recording.
The recording is the absolute reference… not live music.
Then with the recording as the reference point, you are also allowed you own “artistic” license to use whatever playback technology you want to get out of these imperfect recordings whatever sound floats your boat (SET, Class A, Class A/B, Tubes, SS, Unipivot arms, copper cables, silver cables, dynamic speakers, planar speakers, super tweeters, bi-amp, tri-amp, vinyl, DVD-A, SACD, CD, cryo’ed tubes, special fuses, cable lifters, cones, acrylic supports, wood supports, composite supports, blah blah blah)
Me… I value dimensionality (image width, depth, height) over all else. If the middle ‘C’ of the reproduced piano is 99.57% that in pitch/tone of a live piano, that’s fine… what I crave is that my equipment places that middle ‘C’ into the best facsimile of the acoustical space that a real piano generates.
