I am listening to this on Naxos Music Library, which just added it this week. A very fine performance, maybe just a bit low intensity but full of great detail as was noted. Since I have just a "near CD quality" Naxos subscription (comes with my Kansas City SO season tickets) I can not critique the sound, but suffice to say it sounded pretty darn good even at the lower quality. Nothing out of sorts or radical, but a finely done, enjoyable M6. Recommended.
