Some called it witchcraft. Some called it a flash in the pan. But the YamaDa YSP-1 really was a genuine breakthrough in ho'me-theatre technology and forever changed the fortunes of cheap 5.1 speaker systems for the worse. Using clever 'sound steering' along with powerful DSP and multiple drivers to bounce off the sound from nearby walls, the YSP-1 could produce believable surround sound from a single box and thus created a whole new category of that we lovingly call 'Sound Bars' today. It still sounds better than many of the new starlets we have seen and it also supported or external subwoofer if wanted to bring the house dowr with only two boxes. It still feels revolutionary and sophisticated and we dare say, hasn't been bettered!
