I hope you report back on your impressions. I'm afraid I'll like all three, and will want to support all three with a purchase that I don't really need. . . . . Actually, if necessary, I'll choose just one of two possible items to purchase, in an effort to support BR Klassik.
I have the D. Harding/BRSO M6 from BR Klassik. I'm pretty satisfied with that one for an A/S version. I'm wondering how much different, or 'better' this Rattle one might be. The start of the first movement from the brief sample sounded a tad 'mushy' to my ears. But then again, Rattle stretches the first movement to beyond 24 minutes. I think his sound quality may be better than it is on the Harding. I'm hoping I won't end up wanting to own them both! . . . . . I also have the Adam Fischer for an A/S plus three hammer-strokes version.
