This is probably the best of the relatively recent recent recordings of the late quartets. The playing is sensitive, expressive and robust, and the sound quality is crystal clear. However, I have a couple of reservations. Personally, I find the excessive vibrato distracting (and I don't suppose Beethoven would have approved either). A little vibrato is fine for occasional emphasis, but this is too much, too often. (On the other hand, many other performances are as bad if not worse.) The other problem is the recording: there is a harshness to the sound that I find tiring. I'm sure this will vary with the equipment it is played on, but on my system it sounds "digital". Some people seem to like this.
The Beethoven late quartets are wonderful music that will repay much repeated listening over many years, so there is no harm in having more than one recording. There's no obvious "best" set. Personally, I have enjoyed the Italian Quartet, now beautifully remastered by Philips (perhaps a bit too warm and lyrical), and also the Alban Berg Quartet's second set (live in Vienna, with virtually no coughing!). The ones to avoid are the Juilliard (a quirky performance in front of a live audience who keep dropping things) and the Lindsays (loved by the critics, but ruined for me by the continuous heavy breathing and sniffing, and again too much vibrato).
