What amplifier do you use for your Dahlquist DQ10s

I have an Adcom GFA555 currently but am looking to upgrade to a better sounding amplifier. I've been considering Aragon 4004/8008 (Mondial not Klipsch manufactured), Counterpoint SA20 or SA220 (but have heard a lot about reliability issues with Counterpoint), but I'm looking for other ideas. I like the Rogue Audio m150/180 mono blocked but don't want to spend that much. I am using a Rogue Audio Perseus preamp that I would like to keep in my system. Any suggestions or comments are greatly appreciated.
