A Closer Look at the Spitfire MKII DAC

A Closer Look at the Spitfire MKII DAC

Let�s have a closer look at the Spitfire MKII Multiple Input DAC and check out this units build quality:

Front View

With the Spitfire MKII again everything is simple and easy to figure out. We have main power switch, power indicator, Signal Lock, Signal Play, USB usage. The design is similar with the Hex fasteners, case design and materials.  Based on what we have seen, these units are built really tough offering aluminum cases.

Rear View

The rear of the unit is well laid out and simple to connect to your new or existing audio system.  We have stereo line level outputs (L & R), coaxial/optical S/Pdif inputs, USB input and 24VDC power connector.  The Hex fasteners are on the back also to allow access to the circuitry if required.
