I haven’t read all 84 pages, but there didn’t seem many classical suggestions in the pages I did read. Something I have enjoyed is Francois Couperin complete works for harpsichord (Olivier Baumont) - 10 CDs for £20.70 from Amazon. I thought 10 CDs of one composer on one instrument was likely to be a bit daunting but worth a punt at that price. In the event I have listened to them many times with great pleasure.
The background to this is interesting. Back in the 60s I attended an evening class on historic keyboard instrument in the St Cecelia collection. The lecturer played some Couperin on a French harpsichord and I was really surprised by the sound which had wonderful deep bass notes - much warmer and more resonant than the German instruments which could be a bit clattery. I’ve never forgotten that sound and have bought Couperin records from time to time - Raphael Puyana on vinyl, Christophe Rousset and Pierre Hantai on CD, without ever getting that deep bass. So I got the Baumann as one last try, and have finally got the sound I remembered. He plays on one historic instrument and 2 modern copies of period correct instruments.
Another thing I remember from those classes. Harpsichords have vertical ‘jacks’ which rising pluck the string with a quill (raven feathers are best) set in a round hole in the wooden jack. But if you want a different sound you could use leather mounted in a square hole. If you restore an instrument with round holes there is no doubt - it must have had quills. But if it has square holes it has had leather strikers but may have been converted from quill because the square holes are larger. There were 2 restorers at the collection who disagreed about one instrument and each kept a personal set of jacks, one having quills while the other had leather!
