Should you purchase the speakers, why not first try them with the amp you have? That way as you audition other amps you have a baseline as a comparison.
I did that when I moved up from the 3A sigs. to the 5As. I kept the Dreadnaught amp that I had been using while trying others. I reluctantly let go of the SS Dreadnaught after using a ARC tube amp in my system. I really wanted the Dreadnaught to better the tubed amp for two reasons. One, I had bought into the idea that SS was better when it came to amps and didn't want to admit that I was wrong and, two, I didn't want to spend the money.
I'm sure that there are many amps that work well with the 5A's but, I know for sure that Audio Research amps match very well with them, assuming that they also match well with your pre amp.
