I noticed that. They've got lots of juice for 2-4 ohm, but it's cut significantly at 8 (1/4 advertised power).

 

Not only that, but their output lowpass filters are optimized for 4Ω. At 8Ω they start to exhibit a significant peak in the frequency response at 20 kHz.

 

Also, beware their power output claims. They spec at 10% harmonic distortion, which is well into clipping. Best to look at the graphs they supply, and find the "knee" in the distortion curve.
