I haven't bought an amp yet so I will think on that. As far as speakers, I have the 60's, the 150, and 2 qs8 on the side with an old sub and ready to add 2 backs. I would do that over in a heartbeat. I love these speakers. I will consider a smaller receiver after demoing several in the last few weeks. The extra $300-400 in some cases just does not seem worth it for me.
