One speaker definitely worth auditioning if you can find them is the Verity Audio Amadis S. Made in Canada they tend to fly under the radar but they ooze quality and produce some of the best sound I’ve ever heard and never harsh. Here’s a review of the prior model,,,

Other excellent choices in your price range are Rockport Avior, Joseph Audio Pearls, and the beautiful Usher TD-20 (another one that flies under the radar with amazing value and sound right up there with Verity IMHO). Last, and although under $20k I’ll add the Vandersteen Quatro that I think punches well above its weight. Anyway, hope this helps, and best of luck.
