Tplavas, I have in fact tried both Valhalla PC and Anaconda Helix Alpha on the X-01 player, but not during the same sitting. They are both truly great chords. I personally prefer the Helix. The Valhalla is incredibly extended and has no glare what so ever, but it seemed to be somewhat lean in the midrange. In the context of Babybear's system where I heard it, it tended to make the presentation very delicate and 'pure' but slightly two-dymensional compared to the Helix. Having said that, it is purely a matter of preference and of the nature of the whole system. I suspect that on slightly warmer systems the Valhalla would be wonderful.
