This was a difficult decision to make as lead engineer.
Notice that the rear side of The Element is full: power input, power button, gain button, USB input, and a single set of RCA jacks. We'd love to have added optical or S/PDIF input and an additional set of RCA DAC line outputs. But there's no room! The minimalistic enclosure requires a carefully selected features-set. Without delving too much into the business end, analog input is the best path.
The Element is designed as a reference amp first and foremost. Its DAC should be considered an added bonus.
- Removing the DAC has a relatively small cost impact (compare C5D and C5).
- DAC feature-sets and dynamic range will continue to advance over the next few years.
- Configuring jacks as RCA input expands future input capability of The Element
In other words, RCA input means The Element can be used with future DACs with much greater flexibility. This will allow you to connect DACs with greater input and output capabilities.
