F. Chopin - Scherzo No. 1 in b Op. 20 (Complete version) - question plz

[cardinals]

I found that there is more than one minute run time difference from many of other recordings (this one: 9' 50'', average: 8'40'')...what do you think of keeping the tempo around 104 - 108 rather than 120 for each bar?

Also, any other comments for this performance?

(maximum volume setting (both PC and player) recommended)
