In our search for sonic truth, there comes a point where the systems get so good their "truth" is more about our personal preference. In fact, personal preferences often trump truth. We know we've gotten closer to the truth when it matches what we believe to be the musical truth. Of course, no one knows what musical truth is. Even if you were present when a recording was made, all you can really know is whether or not you got close to the studio's monitoring system. That's not truth unless you've managed to copy everything in the recording chain down to the room itself. Maybe it makes more sense to suggest that what we're really after is getting as close as possible to what our personal preferences are. When my system puts a smile on my face I figure I am closest to achieving sonic truth. That's certainly my preference.
