Manley Snapper Triode Switch/600 ohm switchable?


Hi Guys - Im curious if someone can explain a couple of things...

I get that the newer Snappers have a Triode switch for a smooth/relaxed vibe & a punchier/ tight feel....

so the earlier Snappers are just the smooth/relaxed ....new : Triode switch(Ultra linear) is the punchier option with Triode switch...? 

Also ...my speakers are Tekton Encores 4 or 8 Ohm impedance. Snappers have this XLR : 15 Kohm or 600 ohm Switchable....does this benefit me anyway? 

Thanks!

man , do you have an engineer in room to operate everything ..? Must take about 5 minutes to turn on everything...  :) 
Wait , stay away from Russian tubes...? Aren't Tung Sol Russian? 
thanks for the info ! 
Hmm, Tung Sol does not "Sound Russian"....But I could be wrong....Am I? I thought they were Chinese.
 And yeah, "I", am the engineer! Much of that gear is for testing at the time. Though I "Have" had up to 23 individual amps hooked to the primaries at one time! "I have one design that uses 224 mag-planar  transducers simply for the L/R channels. "84 were tweets".
Uh, Tung Sol is a US company, Newark NJ, founded 1907. The name derives from tungsten and sun ☀️
