If you are on a budget and you want tubes, its likely that you will not have a lot of power to spare. For this reason you want a speaker with greater efficiency, and for that reason I feel like a Magnaplanar would be a poor choice.
Zus are popular with smaller amplifiers as they are easy to drive; I would keep that in mind.
If you want any amplifier to perform and show off its 'amplifier investment dollar' its usually best if the speaker efficiency is high enough that the amp is rarely asked to make more than about 25% of full power.
