Nordost Frey vs Quattrofil

I have searched the archives and noticed the lack of information on the Frey and would be grateful if someone could comment on this cable.

I have actually shortlisted the Quattrofil and the Valkyrja as I was particularly looking to add some transparency, speed and dynamics to my somewhat warm-sounding system. I have read that the Frey sounds better than the Valkyrja's in one's system and can be had at a cheaper price. If possible, I would like to stay in the Nordost line of cables.

Any comments would be most appreciated.
