I don't know if the PS Audio Class D amps are the right solution for your system. But I have their s300, at this point I am really happy. PS Audio made me a great deal on my used amp and I had a trial period with the new S300.
Don't have any experience with Classe but There is CA-D200 on ebay for $1.8K claimed to be brand new in box. Although located in Vestal, NY. Classe still has the D200 listed as product on their website. 3 year old review. https://classeaudio.com/pdfs/Reviews/TAS%20CP-800%20CA-200%20Review%20Aug%202015.PDF
