At the heart of AMR/iFI products including the iDAC2 micro is the same Burr-Brown ‘True Native’ chipset which we have explained before in the micro iDSD thread. This particular Burr-Brown chip offers two separate signal pathways for PCM and DSD. What this means is that one chip offers the ‘best of both formats’ as the signal quality remains native. Choosing the right DAC topology significantly effects the final sound. We loved the dynamics and slam of the multi-bit topology (e.g. the legendary Philips TDA1541A), however when a HighDefinition signal is used, the Multibit topology (actually no true multi-bit DAC chipset available yet) doesn’t have the low-level linearity of the Delta-Sigma topology.

As a result, the iDAC2 micro also supports DXD and DSD up to DSD256# . Three Digital Filters are included; Bit-Perfect (Non-Oversampling), Minimum Phase and Standard and three selectable analogue filters for DSD. Running alongside the Burr-Brown ‘True Native’ chipset is the 8-Core XMOS. But with one essential difference – our own firmware. Such update to the XMOS Design and Firmware introduced by iFi include Star Clocking as first outlined in the iDSD micro.
