Speaker Comression models the reaction of the power amp to speaker behavior. XFMR Match refers specifically to the output transformer, which is part of the power amp.Isn't speaker compression a thing that happens to a speaker AND the power amp?...
And transformer stuff, something that happens to the power amp, because of what speaker is connected?... Like most stuff in the speaker page...
If these parameters had been place in the Speaker page, you could just as validly ask why the settings for the power amp are so scattered .
