Took 45 days to ship, and the board was simply wrapped with bubble wrap. Overall the sound is good, but I was expecting cleaner sound and deeper bass ( base on good reviews for TPA3116, it should be comparable to Tripath chips ), there is a noticeable hiss noise if the volume pot is not at minimum or maximum, unplug inputs from the board will get the loudest noise so it's not from the source, and I use lead-acid battery to power it so it's not the power supply either. Unless there is a solution for this otherwise this cannot be used in HiFi applications.

I used one of these amplifiers to make a suitcase sound system. I used a pre amp to get a bit more volume and tone control but otherwise very happy.
