While I have not done this myself, I might be tempted given the amp I currently own (a clone/re-build of a Western Electric 133A amp). The other amps I have are also low-powered amps that require fairly high efficiency speakers. Really good amps make a lot of difference, so it might make sense to at least look primarily at that type of speaker, that is, if I were in the market. Right now, I am more into upgrading my existing speaker.
