Should Genesis V's be toed-in?

I have owned a pair of Genesis V's for a number of years, and have never been able to decide if they should be angeled-in. The owners manual says to keep them pointed straight out, and even advises to "use a tape measure to be sure". However, audio critic Karl Lozier toes his in somewhat. Does anyone who has Gen V's have any thoughts or advice on this? Thanks!
