Excellent Brilliant box for full ownership of Beethoven. Very good interpreters and right versions. I was a little afraid of the sound quality because I'm pretty picky about the issue. I must say that here the sound is generally homogeneous, dynamic, excellent quality, full rather round, never shrill and aggressive with the strings, the sound of the piano is quite ample general. Brilliant Classics achieved a very good job of remastering to provide us with hours of listening to the discovery of Beethoven. Always practical to choose a work in full. A complete, according to taste, other versions for certain works.
