Mission and Cyrus is a well known pairing. I guess if you are used to the sound of a British amp, it’s going to be hard to settle for anything else. But, there seems to be a lot of discussion around the new Class D amps, specifically the ones with the TI tpa3255 chip. Personally, I’m considering giving the fosi bt20a pro a go, costs around 8k from Amazon. There are also other models available, the fosi v3, aiyima a07 pro and the new fosi za3 which all use the same TI tpa3255 chip. Might be worth a consideration.
