[please forgive my poor English]
Very interesting*, thanks. First time I hear the Pnoes...remotely alas :-/
I prefer the Sheherazade excerpt (the 4th movement).
Regarding the 7th of Beethoven, although I can't stand lifted-up or emphasized treble in sound reproduction, I wonder if I wouldn't prefer just slightly more treble on this one; especially here (YT
at 98sec). But it flows and is expressive.
regarding the slightly discrete treble, it reminds me of the Beethoven 7th I heard in Antwerpen the 13th of March, conducted by Jaap van Zweden: the concert hall has a very good acoustics in the 10 first rows, but I sat too far away for
that concert (18th row), and found that the sound was slightly dull there (compared to row 8 and 10), maybe due to the fact that the slope of the pit, in front of the stage, may not be quite
steep enough (=>absorption). The outstanding Namur Concert Hall
does not suffer from that pitfall.
But AFAIU, the system has still "more to unfold ahead".
*Literally; not in the Londonian sense ("Very interesting" = "I don't believe you" OR "that is clearly nonsense"...)
