So is it a waste of money to buy an emotiva xpa2 or xpa 3 seeing how much the onkyo is putting out in btl mode? Thaks for any help in advance
Those are reasonably efficient (90 dB sens) 8 ohm speakers which should be easily driven by your AVR. I had basically similar Polk RT800i towers and they sounded great with a Denon 2809 AVR in an all-Polk, all 8 ohm 5.1 (all speakers set to small, xover=80) system.
The answers to these questions will help us determine whether you are likely to hear any difference with an ext amp:
1. Do you hear any reduction in SQ when you turn it up to the loudest you listen?
2. Are you running a sub, and if so are the fronts set to small, and with what xover?
3. What other speakers are connected to the Onkyo?
4. How far away do you sit and how loud do you like it?
