Yes. I've never gotten into the 4th movement... Perhaps it's just too overplayed, or maybe it's a German-opera thing?! (i've several Wagner Ring cycles - 2 by Solti, & another by Böhm, but also can't seem to muster the patience to finish each piece either). I find the first 3 movements (of LvB's 9th) thoroughly enjoyable tho.
On SACD format, the trend towards music downloads & p.c. playback does not bode well for proprietary hi-res formats (not to mention improvements in redbook by way of SHM-CDs, K2 mastering, etc.). Hope Sony will open up the DSD source. It'd be a waste for this technology (& my many SACDs) to go down the path of the betamex / laser disc / etc.
P.s.: Furtwangler's wartime concert with BPO was performed (grudgingly by Furtwangler) for Nazi officers at the height of the Nazi propaganda machine... (perhaps one of the reason for the tension, ferocity, & restraint?). Don't think you would hv wanted to be there.
