If the speakers aren't very similar in their design and requirements, then yes I would change amps when I get new speakers, eventually. At first I will see how they sound with what I have on hand. Then if I decide they are keepers I start looking into better amplification matches.
On my last speakers I went through 5 or so amps before settling on an Atma-sphere ap.
