^^^ Agree and disagree, and for my example the Oppo HA-1 is perfect. I was indeed wow'd by the detail, bass slam, and the bells and whistles it offered when I first heard it.
Over time, though, I was engaged less and less, not more - IE, I adjusted away from the sound, not towards it. The new normal was not quite as pleasing to me, even though I had used it for months.
I think in many cases you're absolutely right, we do adjust to a component's sound and often accept it. But not in this case for me.....
