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

This amp runs KT88 as output tubes, EL84s as drivers and 6922s as input tubes.  I would guess that it would have enough grunt to operate in triode mode even if that means about half the output of ultralinear.  You could also consider operating in different modes for different music/listening conditions.  Personally, I don't like to fiddle, so I wouldn't do that, but it is an option.

I believe that the triode setting will enhance the mid-range whereas the UL is more linear in freq response. That may help you to know what to listen for. There again, this is the theory.

Good greif! 

YOUR EARS are the judge. It's not technical. Whatever sounds good to YOUR EARS.

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?
