I have Kubelik, Kertesz, Anguélove, Suitner, Rowicki, Neumann along with dozens of single discs, twofers, threefers

. Not a fan of K & K; don't like the recorded sound of the Kertesz cycle and he's too often in a rush. I have the feeling Kubelik wasn't into the early symphonies; sounds like it anyway.
For a complete cycle I recommend Rowicki (Neumann takes the Silver; Suitner the Bronze). Rowicki's is beautifully recorded; naturally balanced but with good inner detail in best Philips tradition. For numbers 1 through 5 no one has done them better than Rowicki. He takes the early symphonies seriously, makes no cuts, and plays the hell out of them. His 6 is among the best too. Re-hearing his Seventh and Eighth Symphonies recently, I was surprised that I'd once thought less highly of them. In fact, they are damn good. The LSO has a precision that rivals Szell's orchestra and a really fine brass section; spectacular horns! A bonus, and a very substantial bonus are the overtures that come with his set. You
must here his Othello!
Individual discs: Mackerras/Czech Phil is by far my favorite 6 (I'm surprised Brian didn't mention him; I think it was his recommendation...or am I having a senior moment

) It gets complicated with 7, 8 and 9. There are so many good performances and recordings.
In 8 you know I look for good and audible horn trills in the last movement, along with a prominent trumpet playing the counter melody to the flute solo about two minutes into the movement (it's astonishing how many otherwise good performances bury the trumpet). Karajan's Vienna boys do a terrific job with the trills. For horns you just can't beat Vienna (they play almost as well for Chung). A big thank you to Scarpia who recommended this CD last year:

Szell and I go way back with the Ninth but Dohnänyi has the better recording. Paita is...different. Insanely fast in the outer movements but with one of the slowest, most emotionally milked Largos. Time almost stands still (nearly 16 minutes long). With Bernstein, time
does stand still (18+)
