Because I dislike not just WiFi but black-anodized hifi, I asked for silver. Here we see the innards of the external power supply with its linear voltage regulators and dual Plitron toroidal power transformers from their Klixon 17AM range …

… and the same show closer up to identify top-drawer Nichicon caps and three vertically mounted Semi On Q J03 in the D1-3 positions.

The main unit responds with a ubiquitous XMOS transceiver for USB data and two quality Crystek clocks for the 44.1kHz and 48kHz audio/video families of sample rates.

 Now top-down views shift sideways to put the Lundahl output transformers into proper relief…

… assorted bits and bobs for which you'd need the circuit designer to explain their functions…

… whilst finishing off with the inside connector housings for digital is self-explanatory. The long perforated casing is for the optical network port.

That signs off on the visual inspection and tech intro except to add that befitting the X1's elevated price, the external hewn-from-solid appearance was immaculate to cash in on expectations in these hifi luxury leagues of streaming DACs. It's where the half-priced LampizatOr SuperKomputer reviewed just prior had played it far more yeoman though it added full server functionality via built-in storage whilst subtracting Lumin's converter from the equation. With LampizatOr you must add a DAC, with Lumin USB or network-attached storage. "You can copy music files to a USB thumb drive or HDD and connect directly to the X1's USB port. Under Music Library in our app, select Lumin X1 USB Server to browse and play those files. To use the Lumin app, you need a UPnP/DLNA server to direct those files at the X1. Our recommendation is MinimServer. Then point your iTunes library at the MinimServer content directory to let it scan your files. Now you can select MinimServer inside the Lumin app to see all of your music."
