Some amps, particularly tube amps, will sound wildly different into speakers with wildly different impedence curves (and there *are* some pretty wild impedence curves out there!) If you get the electrostatic bug, you start dealing with substantial reactance, which can drive some amps to complete failure. Conventional speakers still have some reactance, which can affect the amp. I also think some phase errors are a result of impedence mismatches, but don't really have any principles to base it on - it's just a feeling at this point.Frequency response into a resistive load is a pretty meaningless spec -- no speaker is purely resistive. So are distortion measurements. The amp's output impedence combined with the speaker's impedence curve *can* indicate whether you are likely to have major problems.
In the end you have to listen.
