Which d/a converter? Which preamp? Which headphone amplifier? These are questions that popped up many times in our “audio” life. “Integration” is what spells our friendly dragon as a response. One box instead of three? Let’s see why.
The unique digital processing architecture makes the Black Dragon pretty unique at this price level. Instead of using off-the shelf chips for internal circuitry, dedicated hardware units are built inside a FPGA-chip to form together a powerful and custom front-end to the dac chips. This include digital receivers sampling input signals at 500 MHz , the clock system able to reduce timing errors to sub-picosecond level, the powerful digital filter made with 15 DSPs, the user interface.
The custom hybrid-phase digital filter is a high-performance upsampling block for conditioning the incoming signals. It is especially effective on standard resolution digital signals, like 44.1/48 KHz. With a large number of taps and a carefully adjusted response, the extension and atmosphere of the recordings are virtually enhanced prior to conversion. The filter can be enabled or disabled from the menu interface. For filter detailed performance consult the technology paper.
