Alpha Audio Academy – Series 2 – Episode 2 – Types of Speakers

When we think of a speaker, we almost immediately think of a cabinet with round units in it that move back and forth… A so-called dynamic speaker. But that’s just one type… In this episode we walk past the various types and try to point out the pros and cons. Note: this will be a […]

Alpha Audio Academy – Series 2 – Episode 1 – The basics of a speaker

We open the second series of the Alpha Audio Academy with an important – perhaps the most important – component in a hi-fi system: the loudspeaker.

Alpha Audio Academy – Episode 3 – Tweaks

One of the great things about a hobby is improving a product, set-up or overall solution. Tweaking is what we call it.

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.
