"Much of a Muchness", that's what we got here. I've got a couple of the Osmo Vanska Beethoven Bis issues, along with the much older Bis recording of Sibelius Symphonies 6, 7 & Tapiola [really grand]. I'm one of those chasing everything in Standard repertoire, have been for something like 50 years. Now that I've got a good sounding computer based system, I'm streaming Amazon music and YouTube. There's two other Beethoven Symphony Cycles, of very high technical quality, that I've been listening to recently via Apple Lossless files of the CDs ripped to a tiny 512gb flash drive.
John Eliot Gardiner, leading the Orchestre Révolutionnaire Et Romantique on Archiv is the most fully realized set of Beethoven Symphonies on original Instruments, at original tempi and pitch. There's no bobbles, barnyard noises or caterwauling going on, this is very edgy and coherent playing.
Riccardo Chailly leads the Leipzig Gewandhaus Orchestra using the more or less standard Peters edition, working with a traditional orchestra with a long history with the repertoire. He's also performing using Beethoven's [fast] metronome markings, very successfully. Sound quality is excellent, there's a touch of limiting on the peaks compared to the Vanska sound capture but tone quality, perspective and hall sound are TOTL:
