If you are still looking for mono blocs, you might consider Odyssey power amps.
www.odysseyaudio.com
Klaus builds them in Indiana, and, IMHO, they are excellent, especially given the price, and you can get a pair of Stratos mono blocs with 180 watts per channel for about $2700 before any upgrades.
I purchased a pair of Kismet monblocs in Stratos cases, and the sound quality is absolutely superb; in fact, I am going to have Klaus convert them to stereo so I can vertically biamplify my speakers. I considered replacing them with other amplifiers, but the Odysseys just sound so VERY good that I opted for the alteration route rather than replacement.
The only downside is that you might have to wait a bit for Klaus to get them built, but they most definitely are worth the wait. (I have no relationship to Odyssey other than being a VERY satisfied customer who has talked with Klaus several times not the phone.)
