I have not heard the Classe CAV-180 but Classe has very good amps with a warm sound.
You can pick an Aragon 8008X5 (I had one) in the use market for $2000-$2200. It is an incredible amp for the money. Very powerful, dynamic and smooth at the same time. Also, you can get a Krell KAV-1500 (I have now) for $3500-$3800. This amp is even more powerful than the Aragon. Either one, the Aragon or the Krell will match very good with your speakers.
