ModWright KWA 100SE - used.
No doubt the Gold upgrade will be worth doing if you keep it but agree you’ll be doing good to get what the upgrade will cost if you ever go to sale your amp. Definitely a following for your amp with the upgrade though.
Don’t see them used much lately and maybe still a tad more than what you mentioned, but a Pass X250.5 would be a great choice if you need the extra power.
Parasound A21+ is another amp worth looking into.
