@ normie57,
You might want to read this; it will help you understand the issues of driving a speaker with various kinds of amps.

If you are planning to use an SET, the speakers you have in mind do not seem appropriate. They are intended as Voltage Paradigm devices where the amps you are contemplating are Power Paradigm devices. The combination often results in a tonal coloration (which Al mentions above). If you are planning an SET, more efficiency is recommended to really hear what the SET can do. As a general rule of thumb the speaker in the room should be efficient enough that the amp never exceeds about 20% of full power.
Good Luck!
