So consider this, English is not his native language. And to make matters worse I suspect he does not review his own posts closely so that typos or spell-check sometimes alters what I assume may be his intent.
I had the chance to meet Raul when he visited the US some years ago. I found him to be a gracious and considerate person. And obviously one with deep passion for music and the home reproduction of recorded examples. This passion results in his having direct experience with more different audio components than most us have had or likely ever will have.
So you can read his comments/suggestions and take them to stimulate your own experiments, or dismiss them as you see fit. There are posters here and on other sites who I simply skip over because I've learned we are too far apart in our perspectives that my reading would be of any value. Maybe a few here could do that with Raul if that's how you feel. Peace!
