Sound Anchor stands setup help, plase.

I have a set of Sound Anchor stands for my B&W Matrix 802s. I would like to know: when inserting the bottom spikes in the stand, should the stand be perfectly horizontal or slightly tilted back on the back spike. In inserting these spikes, the front two stop threading in before the back one giving the stand a small "set-back" look. Is this correct?

Anyone's opinions with experience with these stands/speakers would be greatly apprecitated.

Thank you.
