The frequency response and group delay was tested with a 6.6 ohm load.
The distortion was tested under a 6.6 ohm load. The 3.3 ohm load is estimated from 6.6 ohm data. The change from 6.6 ohms to 3.3 ohms did not result in more than a 3dB degredation in distortion performance. The maximum constant real (resistive) load is 150W due to input converter limitations. Test performed at 1KHz.
