I have pair of Aria 926 and pair of Klipsch Forte IIIs in the same system. Proper positioning in room relative to sitting area is critical, both width and distance from wall as well as toe in for both. The Aria’s are way more finicky with position vs Forte’s. Once you find the sweet spot the Aria’s are excellent. Notwithstanding 91dB, they do require more amp punch than the Forte’s. I’m not familiar with your amp, mine is 23 wpc 300b driving 845 output SET, plenty of power. Volume pot no more than 9 o’clock with the Forte’s and same sound level is 10 o’clock with the Aria, plenty of headroom for dynamic transients.
Consider marrying with a good sub, REL or in my system a 300w 12 inch Klipsch reference. Also takes a little position tuning and gain/crossover experimentation to get just right, but once you do…WOW! Bass comes not from sub, but sounds completely integrated with the speakers. Gain for the Aria isn’t even first notch on the dial, with the Forte’s just past first notch and the sub disappears into the speakers.
Finally I’d call the Aria sound detailed, with warm, tight bass, excellent vocal midrange and sparkling highs. Good soundstage, excellent instrument separation. I call it an “audiophile” sound. The Forte’s? Well, much wider, taller soundstage, rich bass, not boomy with penetrating midrane and clear, clean treble. Superior dynamic transients, awesome instrument separation, superior vocal presentation, yes kinda like being there live! They are my “reference” speakers to judge all others (I have other Klipsch, Focals, and Vienna Acoustics in other systems). I listen to country, rock and upbeat pop with the Aria’s, jazz, opera, acoustic folk, blues and low level late night anything on the Forte’s.
lf I could only have one pair, I’d pick the Klipsch Forte over the Aria, but what fun would that be?? Just because you have a pair of dream speakers, doesn’t mean you don’t have a dream speaker! Klipsch Jubilee.
Best of luck!
