hi, Hye Jin!
thanks for listening!
you're partially right about the basses. in fact, I exaggerated the bass a little for two reasons:
1) I had been reading about how Brahms used to play, and he used to emphasize basses too much
2) I wanted to emphasize a thematic motiv in the bass (37", 39") which is the same of the main melody
but then recently I found out these were not working.
I said you're partially right, because I can blame my piano for that too!

those new Yamahas I have played usually have strong bass and weak treble. but I think the reason for that is that they are NEW, and have been played only a little. I think the more I play, the more the trebles become stronger (or maybe I'm just getting used to it...

)
