I have all those Hogwood box sets. They are a little anemic sounding, but it helps to crank up the volume. I also have most of the Roy Goodman Haydn symphonies which I prefer. Back when these sets were being issued there was a debate about having a harpsichord continuo tinkling in the background which Goodman does on his recordings. Hogwood doesn't. Normally, I'd prefer to dispense with the continuo, but it really doesn't make a lot of difference since with Goodman, it is very subtle, and most of the time you can barely hear it. In the later symphonies, he drops the continuo, so it's not an issue. The debate was about which was the more "authentic" way to perform those symphonies.
