QSA’s research has found that the fuse can improve sound quality by up to 70-80%, while a power cord can improve sound quality by only about 20-30%.

QSA’s technology removes Bottleneck Distortion (BND), increasing dynamics dramatically and giving the music an ultra-black background from which to emerge.
