Velvety smooth DAC with the sonic signature sound of a bitstream DAC. Unlike multi-bit DACs, bitstream DACs can offer some of the smoothest sound without the brittleness of multi-bit DACs. Naturally, there are pros and cons when you compare the two so one is not necessarily better than the other. Its all a matter of preference and taste. But for the money, this is an absolute steal. Case has polishing swirl marks but that is very common with DPA stuff.
