By ear, very difficult to take trap, this KA 405, everything is surprisingly clean and precise. washed accident menus that we tolerate with some kindness in some others. Very crystal treble lin, the attacks convincing, without dragging. contribute to producing a listening high quality. with generous breathing, and, whatever the level, the absence of hearing fatigue seduces. Perspective sound is suitable. and the only shadow which remains after long moments of attention comes from some inaccuracies in the bass, not as sharp as in the rest of the spectrum, a little too round, which sometimes unbalance listening. This mentioned imperfeclion, it is doing well moreover the most treacherous furrows and constitutes an object which we remember above all the competitive price/quality ratio.
