ps audio hca preamp and power supply for local pick up only

I have a ps audio hca preamp, which has been modded by the upgrade company a few years ago. I am not sure if the mods improved the original sound but I can tell you that paired with the preamp power supply it sounds great. I will sell both for 700.00 or best offer, this to me is a really good deal. Sorry but it is local pick up in southeastern michigan. This pair is a few years old but works great

whoops I meant to say that it is the pca model, not the hca, thanks
