Pure Note Epsilon cable directionality.

I have almost 200 hours on my PN epsilons and I thought I would reverse the direction (the manual says that it may make a difference). I only listened for an hour or so but there's definately more presence/authority with the cables reversed. I don't know if it's good or bad but I'd like to give the cables another 50 hours of burn-in before I do any real listening.
Has anyone else done or experience this?

Thanks.
