I'm late to the party as I've been keeping a low profile. Kindly allow me to make a few comments:
Like many of us, I am not immune to version fatigue in Bruckner. However, I recently listened to the Vänskä/Minnesota Fourth, which presents the 1888 edition. Based on the "mainstream" 1878/80 version, it includes minor refinements to the first and second movements, while the Scherzo and Finale received more serious changes.
The 1888 edition was long thought to be bowdlerized, but Prof. Benjamin Korvstedt, who prepared it for publication and wrote the liner notes to the Vänskä recording, makes a fascinating case for it. The good professor states that Bruckner worked carefully on this edition and oversaw its performance, and it is the only one he authorized for publication. The changes to the Scherzo were off-putting to me at first, as the higher-pitched horn triplets at the end of the "A" section are eliminated, but on second hearing, I do not find that bothersome, and the refinements in the other movements make the work much more polished and effective.
Quite possibly I will stay with 1878/80 as my preferred version, but I'll also be spinning up both of the others. One could not find a more committed advocate for 1888 than Vänskä, and it helps that both the orchestral execution and recorded sound are top notch. Thus, to my weary fellow Bruckner listeners, I respectfully suggest keeping an open mind for 1888.
A couple other comments about the Fourth: I find it odd that in many recordings, the horns are weak in the 1878/80 ("hunting") Scherzo. The most convincing recordings I've heard are Walter/Columbia (in admittedly dated sound), Böhm/VPO, Blomstedt/SF, and just a tick behind, Herreweghe/Champs-Élysées. If you can live with slightly watery-sounding horns, the Kubelik/BRSO is a terrific performance.
I'm often puzzled by DH's reviews. For B4, he starts by stressing how important, and rare, it is to have good horns in the Scherzo, then proceeds to recommend several recordings where they are barely audible.
I'll also leave a kind word for the first version (1876). While it may never be my favorite, it does have its virtues. While I miss that "hunting" Scherzo, and the original has a start-stop quality that may annoy some listeners, it's a fine movement in its own right, and I think the Finale builds more organically and can make the later versions seem episodic.
Lately I've been listening to the Fifth a lot. It may be Bruckner's most advanced symphony, and in a good performance, the final pages are just overwhelmingly powerful. It does not suffer from version proliferation since we have only the original plus the ridiculous Schalk edition. The latter is worth hearing just to observe what a travesty it is, and Telarc has done us a favor by publishing the Botstein/LPO recording. I have several excellent recordings of B5, and one that impresses particularly is Klemperer/Philharmonia. His set of 4-9 is available as attractively priced FLAC downloads at Presto.
