The SACD release included a bonus track - Valses nobles et sentimentales - that has not been included in the conversion.
The SACD release featured the original quadraphonic mix tweaked to 5.1 by adding centre and LFE channels that I deleted from my conversion. The quadraphonic mix here is "live in the audience" style with the rear channels recorded using "ambience" microphones at the rear of the concert hall, although the choir for Daphne et Chloe performs from the rear of the hall as the work calls for them to be "distant".
