Until I hear better, I'll keep suggesting the Dodd mono blocks with all the upgrades. My room is about half your size but with about the same imp & eff speakers. My musical tastes are quite similar to your own too.
I doubt if i ever tax these amps. they sound great with even complicated musical passages, are dynamic and definitely involving. Easy to maintain, and inexpensive to roll tubes in or re-supply tubes too. Are a slam dunk budget wise used, and a quarter of the budget new. the newer ones reportedly have still more headroom. They are single ended only however, no XLRs. Very nice however.
Albert P could shed more light I suspect, on the Dodds.
Good luck
