I know what you mean about liking a bit of a sharp touch, but there's just something about the tinny, clanging sound that sets my teeth on edge and makes my hair stand on end.
Klassik cannot relate. Klassik has always enjoyed the sound of the harpsichord. Of course, not all harpsichords sound the same. There is some variance between Flemish, French, German, Italian, and so forth harpsichords. There is also the lute-harpsichord, but that's a whole different matter.
Certainly the way harpsichords are recorded can make a major difference. Some close-miking techniques may yield a more mechanical sounding result. :S
Klassik cannot impart any advice on how to enjoy the harpsichord. josh either likes it or josh does not. xD In many ways, the piano and harpsichord are an imperfect accompaniment instrument in many cases as the sound of it can be dominant. For Baroque music, something like the theorbo might be a more logical instrument for accompaniment, but that would not probably not work so well for the Schaffrath oboe sonata Klassik heard as there is more complexity to the bass part that naturally lends itself to the harpsichord. From what Klassik knows of Schaffrath, Schaffrath was a harpsichordist himself and wrote a lot of music for the instrument so perhaps that explains the bass part for that work.
Nonetheless, Klassik did listen to a Schaffrath harpsichord concerto in E-flat and it was a pretty good Galant-style listen. The Andante was a bit dull, but Klassik may have his dull bits at times as well.
