Dear @frogman : I aggre with some of your statements and disagree with others.
"" each piece of audio gear inserted into an audio system affects the resulting sound in one of two ways- it moves the resulting sound closer to, or farther away from the sound of live music ""
There are main characteristics in live MUSIC that can't be matched in our systems.: first is that in a live event seated at near field position there is almost nothing between you and the MUSIC sources but air and that's why that power and dynamics that develops the live MUSIC sources transients and the other characteristic is that natural tone color and rythm in live MUSIC.
So each gear can't puts us closer but farther away. Why?:
Each link in the room audio always alters/degrades the recording MUSIC and that alters/degrades means that recording information even at minimum is losted and added by each single system link developed any kind of distortions the next link in the system can't recovery the losted information and can't disappears the developed distortions but the other way around because what happened in the first system link continue in the more or les same way with all the other links till we listen the final MUSIC sound information.
Now and even that we did not attend to the recording proccesss we can work inside our room/system to stay nearer to the recording if at each system link we choosed good item designs with the lower distortions that technically is possible and that's why my room/system main target is to put everykind of generated distortion at minimum and in this way I will be nearer to the recording and if I'm nearer to the recording I'm nearer to the live MUSIC. can have some good control inside the whole system playback proccess but obviously no control of the recording proccess.
Yes, accuracy is way important and technical specs count about today.
Do you thing that that Dava cartridge FR 6db deviations can puts you nearer to the recording in any room system or that the next system link can do it? NO WAY no matters what because no single room/system link is neutral.
Subjectivity is important but objectivity too and we have to take in count all the facts/obectivity around the playback proccess. Objectivivity along subjectivity is what works and not that " technical issues take a back seat. "
Only an opinion.
