I am not sure I would go with systems listed per OP. For example, I would probably go with the Devore loudspeakers, but if you want them to sound right (especially to play bass right) transistors are not a good idea. They are very tube friendly, and most transistor amps will overdamp the speaker, resulting in some punch but no definition or real impact.
You also don't need a great amount of power with that speaker. So you will have a lot of flexibility with the tube amp used.
