Receivers compatible with Infinity CS-3008 speakers

Hello.  I am new to this and I by no means consider myself to be an audiophile.  My low end Onkyo receiver is severely under powered for my Infinity CS-3008s (clipping at a moderately high volume).  My previous receiver was a Technics circa early eighties model which apparently could not keep up and was recently taken off life support.  Question: What is the recommended power rating for a receiver/amp which will do justice to my speakers?  I am open to recommendations as to make and model, but am not looking to take out a second mortgage on my home in order to upgrade to a better receiver which hopefully will be matched to my speakers (which will probably be the last speakers I ever own in my life).  Thanks in advance to anyone who can point me in the right direction.
