It's not just a matter of output tube, but rather the whole output circuit. You'll definitely want high efficiency speakers, but any of these models will give you that. Now what you have to look at are other things like output circuit type, transformer quality, etc.
There are differences in the midwoofers, over and above how they interact with the circuit. The woofer in the Professional Series four π has a shorting ring, so it generates much lower distortion than the others. It is very clear and detailed. The Stage four π sounds really good too, with full bass and surprisingly clear, rich midrange. The Premium four π is a little darker sounding, more powerful. Each of these speakers is best in half-space, quarter-space or somewhere in between.
