If it truly is going to be used as a ht system, I would opt for (5) ceramic 4.0's all around. The ceramic speakers will add some clarity and have better dispersions than the wood 5.1. Saving you some $ to boot. Add a hsu or svs sub and you'll have an excellent home theater system.
While I have never heard the Ascends, they are getting great press and imagine the above statement would qualify for them too.
