I have used several Bluetooth boards from Sanwu with this chip from ST Microelectronics. Everything required some serious EQ (think Bose 901) to sound presentable. I bought this board to try in the garage as shown in the attached photos. I couldn't get it fast enough. Penetrating, hissing, compressed (@ 19v 4.5A) and 2-dimensional. I'm sticking with my warm friendly TPA3116D2, although I bought this product hoping for a little more SPL.
