Query: Chopin preludes

Naxos has released Cortot's 1926 recording of the Chopin Preludes Op.28. (Naxos 8.111023) The Naxos sound is very good (engineered by Mark Obert-Thorn Himself). A real bargain cd!The Chopin Preludes Op.28 on this Philips 2-cd set are those recorded by Cortot in 1933-34. My impression is that the sound here is a touch warmer and more open than on the Naxos cd.
