Image, detail and soundstaging are very very good. Once there is music, you don't see these speakers anymore - you are in the audio hall, music chamber or whatever. My friends don't believe the sound comes from such tiny speakers.
Excellent build quality, with matched stands.

at 83 Db sensitivity, my 24 Watts Unison Research Simply four cannot reach high volumes.

I added a subwoofer (Velodyne 12 inches), then played with different speaker cables and interconnects and once tuned I didn't need the sub anymore !
But what a great sound ! A speaker which looks as good as it sounds fantastic.
Not for big rooms or add a sub.
