Although I must have heard every beat of No.5 elsewhere - you know: ta ta ta taaa - I have never had a disc of my own before. This version is neither too solemn nor too mechanic, just fine.
Why an extra disc for No.7?
It is just superior regarding the music. A Must-have I'd say.

Both SACDs are hybrid multichannel.
