I have recently listened to both Anaconda Helix Alpha and the original Anaconda Alpha on the same system. My detailed observations can be read at:

While I much like the Helix over the original anaconda, and am very much in love with it, I am not sure that the apellation of either neutral or warm even fit the Helix series at all. The effect is much more that of a polarizing filter deepening and saturating sonic colors, letting more of the music through and cutting off that stray glare that seem prima face exciting, but is in reality nothing but distortions.
