After just a couple disrupted listenings (on headphone, car, & computer speakers), here are some details that might be of interest. Sound stage is wide, transparent, but rich. Winds and brass, to which I am more attentive, performed admirably start to finish. At the start the low strings have the 'scrubbing' of the Bernstein VPO but the tempo is more deliberate. The cowbells are shaken, dense, and very distant (a large herd far off to the left?) with a a wide tonal range: the high tones are reminiscent of Bertini's, but the aggregate sound is 'organic'. Flute entry in middle of Andante (51?) is well done. Scherzo is slow, but attention keeping, not perfunctory. It ends with some momentum, not lethargy. Movement IV is not limited to relentless loud and louder dynamics. Thankfully, the hammer blows bear no semblance to those on the Baltimore recording. Though there is no tam-tam augmentation on the second hammer, it was from my perspective the summit of the movement. What followed was the staggering to an ultimate demise: the final crash is less startling than some others; the pizzicato is truly piano.
I've had 26 version of M6: the keepers in my collection are Bernstein, Boulez, Farberman, Jansons/RCO, and Mackerras, not all for the same reason. This will join those.
