Hi Tony,

The Pioneer Elite models seem to be fine with 4-ohm loads. Besides Denon, the other brands that historically have had no trouble driving 4-ohm loads include Rotel, NAD, Harman/Kardon, Sherwood Newcastle, and upper-level Onkyos and Yamahas. It's the old Onkyos with ultra-sensitive protection circuitry that balked at 4-ohm loads. More recent models of Onkyo and Yamaha in the mid-to-upper priced range don't seem to have that problem.

Regards,

Alan
