Try risk free Crown XLS4000. It's pro audio amp capable of delivering clean and detailed sound with gobs of power for 801's. To my tastes it's definitely better runner vs. McIntosh 452 and it's small fraction of the price of all above mentioned with money back from most of pro audio dealers.
There's also a discussion here about downgrading to pro-grade and remaining super-happy with performance and built quality.
Sounds crazy ($800 amp for $10k speakers), but worth trying
