About 20 hours of listening. With my rig, the similarities between Nordost Frey2 and the Audience Au24sx are striking. The midrange performance seems to be the sweet spot with the Au24sx. The Transparent Reference is the runaway favorite for me. Better base, softer trebles, absolutely quiet. They should be better at twice the price of the other two cables. Regrettably, the Au24sx does not play well with my B&W 803 D3s as the tweeters can be a bit challenging to tame.
Since I never heard the Se version, I can't express an opinion in terms of improvement with the new version. I will say that these cables appear to be an excellent value and I am disappointed they did not work out for me.
