S.M.S.L SU-6 DAC: Packaging and Accessories

SMSL uses a predominantly white cardboard box for the SU-6 DAC, with black accents to call out the product name in addition to the company logo, the now-expected Hi-Res Audio logo, and a render of the product on the front. Product certification and contact information for SMSL is seen on the box too, in addition to a sticker confirming the exact color of the unit inside. The box has side flaps which open up to reveal a thick foam sheet, and an even thicker foam lining with compartments to fit and protect the various items included with the SU-6.


SMSL includes a warranty card with the SU-6, as well as a multi-language user manual (online copy found here) that walks you through initial setup and use of the DAC. As with most standalone DAC units, the SMSL SU-6 takes external power from AC mains and no doubt has a transformer inside, given the absence of an external power supply brick. This is different from the TOPPING E30 II we saw recently that instead relied on a 5 V plug going to a USB Type-A port instead. SMSL also provides a white USB Type-C to Type-A cable for USB data connectivity, it would have been nice to rather see this in black to better match the unit. Another thing to see here is the optional Bluetooth antenna indicating Bluetooth input as a connectivity mode on the SU-6 in addition to wired connections. There is also a handy remote control to help navigate through the various functions easily and to make the most of the DAC. It has dedicated buttons for a lot of things, including shortcuts and navigation between the various inputs, changing the unit output volume, and so on. The remote is predominantly plastic and won't win any build quality awards, taking two AAA batteries that SMSL does not provide in the box.
