Duphly is nice
The 2nd CD you posted is cool in that it's played on the "Lefebreve" harpsichord that Skowroneck built for Leonhardt after a bet that Skowroneck could produce a "fake" antique harpsichord that would fool experts.
Some other Duphly I like (Sadly, I don't listen to him enough -- sometimes, his works sound too "classical" to me, or just get overshadowed by people like Forqueray or Royer)
Elisabeth Joye's version on alpha is excellent - great harpsichord (The anonymous early-18th century one in Assas that Scott Ross and Jean Rondeau recorded on), and sensitive rubato. Somewhat dark, melancholy, in mood.
Rousset's I haven't listened in detail, but it seems pretty typical Rousset: muscular and full of force. Worth a listen.
Gluxam's Duphly is excellent - much less brooding and rather more balanced than the former two. The agogics are delicate, beautiful, and in the best of tastes.https://www.youtube.com/watch?v=eXiIBoR4wks
The Duphly on Baumont's Quentin De La Tour Musical Portraits, and Skip Sempe's A French Collection is also excellent.
Edit: I forgot Leonhardt - doh!
