With respect to you and Mr. Toole, I am not much concerned with statistics as I'm listening, or any other time for that matter, but that's me. YMMV
I have and do enjoy growing my system and trying to make it better with every step. I hope that never stops as it brings me great pleasure! I love cueing up a record and hearing all the detail no other means could give me, but that doesn't mean my enjoyment of the music is greater. Sometimes it is and other times it's not. I fail to understand why only a top-notch system can provide more enjoyment.
I am not concerned with statistics when I am listening, but I am when posting and reading opinions. And it seems to me there is a misunderstanding in one important point - I am not addressing top notch systems, just improvements. I am not telling that (and I think no one is doing it) only a top-notch system can provide more enjoyment. , but that in general a better system will provide more musical enjoyment.
