You're on a good track. Even with SET amps, there are a number of different tube types which each have their own relative strengths. For example's sake (please don't flame my oversimplification here):
845 - a bit more powerful, good dynamics & bass slam for a SET type
300Bs - beloved midrange, magical vocals, acoustic guitars, cello, etc.
2A3 - great imaging, traditional warm tubey colorations
45 - lowest output, need highest efficiency speakers
Try researching articles like this to learn more on the differences:
