The N802s want to be bi-amped, though doing this actively becomes very expensive. My recommendation is to bypass the Rowland (quality at a price), and drop into Bryston 4B-ST, per Speaker, or using two of their 250wpc powerpacks (you can put these behind the speaker, and keep your speaker wire expenditures to a minimum.
The Bryston is not in the same league as the Rowland, but you don't need to spend that kind of money and amps.
