Lovers of early music will not be surprised.
Listen for yourself.
The Haydn symphonies set is superlative in all respects. It's not complete: 1-75 with a few extras. For anyone who needs the full cycle Fischer is availbale from Nimbus in MP3 format for about $25
Nimbus MP3 sets are also available of the Bowyer Bach organ music and the Lester Scarlatti set -- both are ridiculously cheap and splendid.
