Any decent speaker amplifier is capable of driving even an 800-ohm headphone with no trouble-- it's the portable gear that chokes on high (or low) impedance. Unless this [unspecified] Onkyo is an unusually bad amp-- I'm assuming it's a 2-channel stereo receiver-- I'm afraid it's the sound of the headphone itself that you find "lame". I'm assuming the headphone is wired properly and the cable is in good condition.
As a last resort, try driving the headphone from the speaker terminals. It's possible, though not likely, that the Onkyo has a separate (and bad) headphone amplifier built into it. Try it by having a friend hold the wires on the plug: both black speaker terminals to the sleeve, left and right red terminals to the tip and ring, respectively. If this sounds better, you can solder up a simple adapter. Hope this helps.
