I recognize that this is entirely subjective and system dependent. But I'm not running a science lab, I'm just listening to music I like at home on my modest system. If the positive results to my ears are consistent, and they are, that's really all I care about.
That's how I look at it.
I don't worry about whether or not it's due to actual audible differences. The ultimate goal is simple personal enjoyment, however it may come about.
