well... due to an embarrassment of riches in the speaker department, (i also have a pair of diapason adamantes lll's & a pair of coincident victory's), i am not presently using the proacs. it's not that they are in any way lacking, but i am just trying different things. but, w/the ref 8 sigs, i have successfully used a mesa baron, a manley stingray (the ~25wpc in triode mode was plenty, in a ~14x22x10 room), and a pair of 40w audio mirror 6c33c set monoblocks. i have used varied s/s gear, including vintage sansui au719, revox b251, & more modern thule (i forget the model). all were outstanding, but i am partial to tubed gear.
even tho the proacs aren't presently in use, i don't have any intention of letting them go any time soon. however, when the gr research ls9's come out, i may be tempted to part w/two of the three above-mentioned speakers to check out a pair of those. not sure which two would go... hmmm... aa
