And then there’s the "heart" of this player -- the digital-to-analog converter, which is quite special. Although Arcam prides itself on building things in-house, the company went outside and worked in collaboration with Data Conversion Systems (dCS) for the DAC. dCS is another British-based company and conveniently located in the same area near Cambridge, England as Arcam. One of dCS’s many claims to fame is something it calls the Ring DAC. I was given a pretty thorough technical description of Ring DAC technology by its inventor, Mike Story, but suffice it to say that Story talks way over my head. The essence of his explanation, though, was that this innovative 24-bit DAC of his is intended to reduce non-linearity at low levels -- a problem that has plagued DAC builders for years. The Ring DAC is proprietary to dCS. |
