How about the discontinued CTS series from Crown? (class AB up until CTS 1200, while CTS 2000 and 3000 are some class D-ish design). The multichannel ones (4200 and 8200) seem to have even better specs than the twochannel ones. Lots of cheap ones to be found on ebay. Need fan swap though. https://www.crownaudio.com/en/products/cts-4200
Do those specs qualify as high fidelity?
