The BC509 and BC507 digital to analog converters share the same decoding engine. The difference is in what size fuel tank and what kind of fuel they use.
The Digital to Analog Section:
The digital to analog part of the machine will support anywhere from 16 bits to 24 bits - 30KHz to 216Khz and anything in between.
Every signal trace on board has been carefully designed and tested.
It features a complete DC path to ensure ultra low jitter performance.
Another feature that adds to the signal performance is the microprocessor is not used in the control circuit. The less the clock contaminates the signal the better.
The BC509 has a power supply filtering capacitance over 200,000uF. That is more than most 100 watt stereo power amps. This will ensure a very stable power supply, however for the ultimate goal of a silent running power supply, the BC507 has a 1,000,000uF (1 million micro Farad) additional battery power supply. When running off the ac power line, there is no ground hum or any sort of noise caused by the powerline that can be detected by the audio circuit. The result is a blacker than black background which has a major impact on the micro detail of the musical presentation. This is one of the major factors which contributes toward that elusive sense of effortless and dynamic yet relaxed musicality.
Inputs:
*Standard config: (1) Toslink, (1) SPDIF, (1) AES/EBU
*Optional: USB 24/96 (will also support 16/44 and 16/48), USB 16/44, additional SPDIF
Outputs:
Standard config: (1) pair of XLR balanced, (1) RCA unbalanced
