"The Action Ultra’s midrange is harmonically rich and a little warm but still open and communicative. The treble is open, airy and, if not ultimately detailed, still nicely refined. The combined sound is very well-balanced and easy to sink into. Especially smooth jazz turned out to work a treat."
"It sounds energetic, with good drive and dynamics. With its mildly warm sound, it has an easy-going character with a very natural timbre and it is easy to listen to. "
