Details

QSA stones come in four different varieties, are about 37 mm wide and 6 mm high including the gem stone on top of them. This time, another color doesn’t mean “better”, unlike the QSA fuses and outlets, they simply all cover a different part of the audio band.

Black gem stones

Red gem stones cover the higher bass frequencies and lower midrange, resulting in a “warm” sound. String instruments and the human voice all sound fantastic.

Blue gem stones cover higher frequencies, from the upper mid band to the lower part of high frequencies, resulting in an “open” sound. Anything reverb-related expands further.

Clear gem stones cover the real treble, the high frequencies. Cymbals, hi-hats are clearer and decay longer. Hall ambiance is enhanced and overall clarity and transparency are improved.
