It sounds much better with a new perspective; I was listening with headphones before, and after checking it out this morning on actual speakers it's improved.
The piccolo is still oddly present for me, but I don't think it's a dealbreaker anymore. I've never heard the piccolo part there before, so to just suddenly hear it front and center threw me off a bit. Sort of like how the harps are in Paavo Järvi's M2.
I still think Bychkov lacks drive in the big spots, but the orchestra sounds incredible. Great horns! And I love the timpani playing, those subtle crescendos at the end really come out.
As for the very last note, Bychkov seems to do the "Bernstein thing" of adding a loud percussive hit. Although instead of a bass drum, this sounds like a very loud timpani hit and I think I prefer it. What do you guys hear, bass drum or timpani? It would have to be a low D on the 32" timpani, which is VERY low (sometimes so low that it doesn't produce much of a tone). I think the timpanist is playing D octaves on the last two notes (think like how they do F octaves for Beethoven 9 scherzo, which is funny because that movement also opens with D octaves for the orchestra).
