I already have one Kappa Perfect build and am more than happy with it... I will be making another one soon.... I was thinking about trying the next one with the same enclosure but using the Shiva X instead of the Kappa Perfect just to compare the two. I hear the Shiva will work great. It has more xmax than the Kappa. I am certainly not an expert but do any of you experts think this is a good idea or should I stick with the Kappa? Oh and by the way... the big reason I am thinking of trying this is because the Shiva is on sale.... http://www.diycable.com/main/product_info.php?products_id=653
