The machine is awesome, I paired it with a Yamaha home cinema amplifier and a 4-channel DJ mixer. The build quality is excellent, it has many conveniences with the front crossovers, the sound quality and the differences in sound are simply incredible. It has good connections, for example, I connected a Rockford Fosgate iBeam bass subwoofer (it has a subwoofer output) to a power amplifier using XLR and it plays better than the Yamaha. I got it for 184 euros. Regardless, it is an awesome tool, a must-have for those mainly involved in recording and music production, but it also enhances our listening experiences.
