A friend of mine has two pairs of Niles Audio RS6's in Sandstone and they sound great.

He's powering them from zone 2 of a Denon DRA-697 Stereo receiver and a Parasound HCA 855A power amp (85 WPC into 8 Ohms). The 2802 is 90W into 8 Ohms and so performance should be similar.

They're reasonably sensitive at 89dB and are 8 Ohm speakers (probably your best bet if you're using the receiver's internal amp).

I have had a pair of Niles OS-25's for more than five years that still sound great.

Best of luck.
