The Alpha Dac Series 2

The Berkeley Audio Design Alpha DAC is perhaps the finest and most versatile DAC available at any price in the high-end marketplace today. If you are considering the purchase of an outboard Digital to Analog Converter, the Alpha DAC should be at the top of your list!

“I’ll have a lot more to say about this extraordinary new product in my review next issue, but for now you should know that Berkeley’s Alpha DAC Reference redefines what we can expect from digital playback. The Reference is simply stunning in its ability to render instruments as real-sounding objects in three-dimensional space. This startling -and I mean startling- quality is made possible not just by the Reference’s spatial precision, but also by the timbral vividness and extraordinarily high resolution of the tiniest micro-details. What’s more, the Reference performs this magic trick on all instruments simultaneously, even in the most dense and complex passages. This unprecedented (for digital) quality allowed me to easily follow individual musical lines in a way I never thought possible from digital. The build-quality is many steps up from the original Alpha DAC, including a chassis milled from a solid aluminum block. The Alpha DAC Reference is an unqualified triumph. (Review forthcoming)
