Gentlemen, the device is very interesting. There are some inputs like USB, SD and Analog. There is radio too. And we still have the question of cost benefit. The negative side is that there is a lot of background noise, but for me the positive side overcomes this negative point. I didn´t like the lights, but that's my taste.
Good amplifier. Power is 20w per chanel. Decent sound. Bass could be stronger. Reads usb and SD without problem. Radio is usable but signal must he strong. Looks are OK. For the price it is very good product.
