That's one of those reviews where you just want to say "don't hold back Dave, tell us what you really think!"
I didn't know they used a harpsichord continuo for the bass line, that's more for Gurn, pass. 
Except... he doesn't say anything in those excerpts about the quality of the performances. Nothing. And the numbering of the symphonies (105, 107, 108) is not exactly novel or unique to DRD... it's one of the traditional ways. He pretends not to know why 106 is missing to make a point... but it is disingenuous entirely. Ditto his deliberate misreading of the liner notes. (They were recorded in the span of about four years.)
I've not listened to more than five discs of the set yet, so I can't really comment... except that I like the idea behind DRD's Haydn and that I, too, think that the applause didn't need to be included.
