I don't do Apple, but if they're offering lossless files, I would take take that deal!
Waiting for the French Sony CDs to come at an affordable price might take a while, and waiting for Sony Classical is...how long are you planning on living?
But this set of music...I have other sets, and it's one of those things where there are differences, but there is not "better".
It does appear these performances are on Apple music/iTunes. How "legit" is a bit hard to say, but I'm certainly willing to listen and decide if it does merit chasing down the CDs. I am gradually moving away from buying physical media, as the house is just too damn cluttered, but there are always exceptions to be made...
