...First, this is a sonic delight. Especially if you have an above average rig. ...
I listened to mine... once... in the car... It is a lousy place to audition such a great performance, but I liked everything I heard (though it has to be amplified to the highest levels). I don't own SACD equipment, at home, so I know I'm missing the real sonic pleasure.
As an amateur horn player, I have to say the PSO section is dynamite. Bill Caballero is a master principal. From the sassy licks in the M4 to the quiet, mournful playing of the Misterioso in this M3, his playing is skillful and tastefully nuanced. If the M5 really is next, I can't wait to get it!!
Chalkpie asked elsewhere "Does this replace Chailly, Bernstein, Salonen, Boulez, etc?" I have the latter three but did not keep the Chailly recording for reasons I can't recall (in fact I haven't kept any of his RCO recordings, only the RSO Berlin M10). The Bernstein M3 I have is the DG version: I like it though it is a tad long in places (and overall >105 minutes). Interestingly, the tempi in Bernstein's Sony recording (I do not own) and Honeck's are very similar: by my math the recordings are exactly the same total length at just under 100 minutes. I very much like the Boulez M3 with the earthy-toned VPO, although it is over four and a half minutes quicker (mostly in the last movement). I originally had doubts about the Salonen M3, even faster than Boulez, but warmed to it enough to keep it (probably for its fine playing).
I have no problems with the PSO trombonist's solo. I believe Joe Alessi was the NYPO trombone soloist in Bernstein's M3, and Alessi's performance is my standard to which I compare all others. Moving over to the trumpets, I have to say this PSO trumpet section is stunning. Trumpets are very directional and it could be that this bunch is always pointing at a mic, but I rather suspect that they simply have lungs and lips of steel.
Changing gears entirely, Michelle DeYoung sounds very mature, and her "..sch" in IV is much less pronounced than on other recordings I have of her singing this movement.
I've listened to the entire last movement as I composed this note, and the two words that come to mind are splendor and power.
Pittsburgh is really a fortunate city to have this orchestra and conductor.
