Ah, I wasn't aware of the mention of a 302 in a prior thread. My bad. The 502 is still a 'low end' receiver but I picked it up as a stop-gap while I was waiting for the 702...and yet I still have it. Now the choices are even greater and I'll probably get the 705 this time around. See, good things come to those who wait.
Anyway, even the lower end receivers can drive reasonably sensitive 8 ohm speakers to great volumes. Sure they lose composure a bit at those higher levels but who can stand that level for long?
