Phase inverted..why?


I just bought a Rogue 66 Magnum.
Its design is phase inverted.
I have to switch the polarity of the speakers cables.No big deal, but Im wondering why a product would be designed like this.

I'm somewhat confused and, obviously, not an electrical engineer. However, if the solution to the phase inversion problem is to reverse the speaker cable polarity, why don't the manufacturers just wire the output that way in the amp.

Sorry for the stupid question.

KISS? is that a secret message or does it stand for something? :~)
Would someone please answer Wstritt's question. I have always wanted to know this. Wouldn't reversing the internal wires to the preamp's output jacks put the signal back to correct phase?
