The design of the HDA range draws upon all of Arcam's experience as one of the UK's most respected audio companies to produce Arcam's best performing range of audio products yet - using the best quality components and engineering practices the HDA range is designed and built to give you years of listening enjoyment. Our most advanced cd digital audio and network streaming player yet. In a sense digital audio doesn't exist. You'd have to be a particularly dull superhero to possess ears that can decode the millions of 1's and 0's that make up your CD collection or iTunes library. Whatever the source - be it a laptop CD player smartphone USB stick - the result is just a vibration in your speakers. In other words it all winds up analogue in the end. Arguably when playing from a digital format the most vital component is the DAC or Digital to Analogue Converter. We'll spare you the bulk of the science but this is what translates that otherwise lifeless binary code into audible sound energy. Bit-depth meanwhile is a key measure of audio quality. So if you're listening to a 24-bit WAV copy of your favorite album through a DAC that only converts to 16-bit there's a good chunk of detail going to waste right there. That's why we've included 32-bit DACs on the entire HDA range - the most commonly used bit-depth in digital recording - so you're guaranteed the full aural picture of whatever the artist intended.
