XLO Signature 3 or RSA Poiema 3

Anyone have a chance to compare these cables? I will purchase one of these, just looking for advice.
If your buying new go for the one with a return policy..If you don't like it send it back and buy the other.......If your buying used I can vouch for the Ridge Street Audio Poiema as being an excellent product..Can't say if its better or not then the XLO.........
