Integrated amps for Joseph Audio rm22si

Looking for something that doesn't run me out of the room after 15 minutes of listening to it.definitely don't want something that's going to be too edgy or bright something with good low end detail. It seems Joseph audio prefer's class D amps or at least that what they use at the show from what I've seen. Something I would be interested in trying. 

The only thing I have so far are the speakers and some audioquest cable's rocket 44 speaker cables and cobra interconnect. So... I thought I would start with the amp first and then the source.most likely cd
