Tube Amp settings: Triode vs UL; 8 ohm vs. 4 ohm ?


Hi. Advice please. EL-84 tubes. Cary Rocket 88 tube Amp. Klipsch Forte 8 ohm speakers. 
 

I can Triode Class A this amp, or A/B it on UL?

I also am blessed with switches for Ohm: 4 or 8?

 

Speakers efficiency is upper 90’s db

What is the decision process for settings?

Thanks for responding. I should also say that perhaps consideration should be given to my Micro 3000 SVS Sub, related to the Triode vs. UL switch? As some will know the Sub settings are “ on the fly now with SVS installing their App on your phone?

Thanks to all responses. And add to that a Schitt equalizer in the midst… it’s truly a Smoothie to any harshness on my Forte Ones.
