I quite agree with the other reviewer of this CD; it is excellent and well-worth buying. The mid-1990s Naxos Beethoven symphony cycle is far ahead of much of the competition. I particularly like the chamber orchestra like approach, thus removing some of the needless "weight" from these works that features on many "default" recordings.
The Hungarian orchestra has been augmented for this recording to a size a little larger than that suitable for, say, Haydn, and has a particularly strong woodwind section.
This is an immaculate performance in spectacular sound, with a really good choir and soloists. Perhaps the reading is a little middle-of-the-road, compared to those performances emphasizing the "spiritual" approach to Beethoven (like Furtwangler & Bernstein), but that's fine for me. A good choice, especially at the prices you often see this CD for!
