Delivery by taped cardboard outer revealed this branded inner black box with chambers in the foam cladding for the cables, power supply, remote and manual. The German sender hadn't included the cylindrical footers which, as Anchi Chang explained, "are for listeners not able to place the cube speaker in the right place and for an audience who would like an even better listening experience. As such, our footers are optional accessories." No matter, I had plenty of useful stuff in the utility room's hifi grab bins.
Here we see the longer stock cables plugged in and the switch-mode power supply brick seated. A Toslink cable with one molded mini plug and a 3.5mm stereo link still stood by to look for a suitable source.
For infrared-era fossils like our household's, the biggest omission of the concept is a USB input for wired streaming. We still need a small AudioQuest-style USB bridge. soundgil instead appeal to the Blutooth nation whose mutant brains are impervious to the involved radiation and don't mind the lossy format. With Jean-Marc's review having covered that territory, I'd focus on wired alternatives and thumb-drive media.
With X-ray vision, one would see that the Cubes are actually squared as in, cubes within cubes. An inner clam-shell casting with irregular thicker walls sits inside the outer dress box with thinner walls.
It explains why handling calls these bricks super robust and weighty for their petite sizes.
For a final surprise, consider the very big mbl system by founder and CEO Mark Chang which was documented and photographed by Chinese magazine Audiophile in this PDF article. It was his sonic inspiration and yardstick to pursue shrinking its physical and fiscal footprint into something a budding music lover and first-time audiophile could afford and house. When soundgil call their Cube system "your first step into the high end", they have a very real reference in mind.
