any thoughts on the Arrau Beethoven Piano Sonatas set? I'm also adding this to my list of sets I'm listening through concurrently at the moment. I didn't know till just now Hurwitz has this as his reference recording for a set of the complete cycle.

There's the slightest hiss which is a shame, however it's under the threshold of annoyance so don't worry.
