Upon first listen, you are struck with the vast soundstage that stretches way beyond the sidewalls on many recordings. It's also deep, reaching easily to the back wall of the listening room and into the corners to define the size of the recording venue. The excellent dispersion of the Arcus also allows a generous sweet spot for more than one listener, a luxury not afforded by a good number of speakers. Focus and imaging are excellent. Drums and percussion sound natural as do strings, with cymbals, bells and other instruments in the higher registers presenting themselves clearly, cleanly and without negative artifacts.
Piano can be glorious, depending on the recording.
The Arcus is a dynamic speaker, warm without coloration, transparent without a trace of edginess. The speakers absolutely disappear and you hear nothing but music. They enjoy rock as well as classical or jazz, and like to played with gusto. The common thread here is the musicality of the speaker. They draw you in.
