I can't speak to the high pricing of the Pharaoh, but the Sphinx is an "entry level" unit and according to Rogue's website, the Pharaoh is vastly superior. Balanced XLR inputs, higher quality caps and electronics, I'm assuming a larger pwr supply...it doubles it's power output: 175 WPC/8 ohms, 350WPC/4 ohms.
I'd love to demo it, but it must be something special for that price.
