Speaker matching is pretty important, as a general rule of thumb the speaker should have enough efficiency so that the amp never makes more than about 20% of full power. This is so if you want to really hear what the amp is about.
With SETs the smaller the amp, the better. This is because it is very hard to get bandwidth with single-ended output transformers. Initially, the 300b was king; by the late 90s the 2A3 took ascendancy; now days the 45 is highly revered.
