Workshop – Purifi Eigentakt EVAL1 power amplifier

In this video workshop we will assemble a Purifi Eigentakt EVAL1 amplifier. In other words, this is Purifi’s stereo power amplifier. In addition to the EVAL1 board, you will need an SMPS1200 from Hypex and a nice case. We chose the Ghent audio EVAL1 case. It looks pretty nice and is not too expensive.

Putting together your own device is incredibly satisfying. Even if it’s relatively simple, like the Purifi EVAL1 kit. All you need is a Phillips screwdriver. A pair of pointed pliers is handy and if you want to work really neat, some tape is nice too. That’s really all you need to assemble this beautiful amplifier. We are still going to judge the sound of this new generation Class D amplifier. So this is not a review of this amplifier.
