Rated 2 out of 5 by from Great sound, but! I'm using this device sice a year now and i'm really satisfied with the sound quality. The bass is vibrating while the high tones remains clean, and you can get an incredible-level of bass if you turn the knob at the back of the subwoofer. A beast. The reason i'm giving 2 point is that there's a power-saving "feature" implemented in the device which you cannot fine-tune or tur off. This feature combined with the fact that it takes approximately 1 second for the device to recognise audio-format leads to an issue where the device "cuts off" the first second of every song i'm playing, which is unacceptable (!). The recommended solution for this is to feed the device with constant noise if possible (with an aux cable, turn the source volume near maximum and lower the volume on the soundbar - in a reversed order so you won't accidentally destroy your home with the sound pressure - so the constant noise won't let the soundbar go to power-saving mode), but this really isn't a professional approach, and also not fixing the issue if the input is digital, which doesn't have the "necessary" noise to keep the soundbar alive. I really wouldn't recomment this device to anyone until the power-saving feature is fixed (with for example increasing the delay before the device entering power-saving mode, resulting that it's forgetting the audio format from the previous seconds)
