This is an interesting concept but What does it mean to "load" and "idle" SET and how is this accomplished without changing the speaker it's driving? 
   
The "loading" and "idling" in SET is amount if impedance the out tube plate is loaded upon. Mostly it managed by the ratio of output transformer, that is why many output transformer have multiple taps, or even better the re-mapable section, that you can change the ratio of the transformer and effectively how much load the tube "sees". There are many other ways to do it of couse.

And now I am very curious to try something different -- SET, and how SET sets my mind. I do not know what to exactly expect. So the question is what SET should I bring home. Maybe Single ended pentode, but in either case it makes no difference because I do not know both. And with this in mind, there has to be way to narrow down to one amplifier to try. I don't have a friend with SET to let me try. I thought to start by setting the lower power output limit. I do not like to limit myself to only quiet listening. With 1-2 watts amps I don't know what to expect even with 106db speakers. There is a reason you probably do not use 2 watt amplifiers?  
   
I do not know what ask and I would anyhow stay away from any specific recommendations.  You live in Chicago and it is not an Antarctica – you will find someone. I doubt that you need to make those SET experiments. I do not what SS amps you use but if they are good amps then getting rid of active crossover and go line-level shall give you very worthy and very predictable benefit then chasing a murky SET ideas.
