Excellent Discrete R2R & 1Bit DSD DAC
Different from A> DAC which has been popular in recent years, it provides a more natural sound. However, this architecture needs precision resistors and deep development to achieve fine performance. That’s why the GUSTARD R26 adopts a R-2R ladder DAC to convert the digital signal to analog signal by switching resistors' array. Besides, the R26 utilizes a native 1 Bit DSD DAC, supporting DSD 512 (via USB) and DSD1024 (via IIS). The DSD stream is decoded by the independent 1 Bit DSD DAC without DSD to PCM converting.
10M K2 Clock Synthetization
The GUATARD R26 replaces the input signal's clock with precision oscillators (local or external), which can avoid the interference from the input source's clock. This device will function off when using IIS, AES, COAX, OPT, BT, PCM NOS, and 1Bit; function on when using USB and LAN. It is worth mentioning that the ultra-low noise K2 clock synthesizer can provide precision clock from local oscillators or external clock in.
Low Pass Filter
LPF is specifically designed for the D/A converter using discrete devices. Final parameters of the circuit are adjusted with subjective listening. Different from ICs, discrete circuits provide the possibilities to control every detail in sound and performance. But the parasitic effects introduced huge challenges to development experience and device's quality.
Complex Programmable Logic Device
The R26 Convertor features a complex programmable logic chip to construct logic function of digital integrated circuit. In addition, the GUSTARD DAC features signal routing, the clock management, 2nd order PLL, DOP decoding, and depop for PCM/DSD, all of which lay a solid foundation for excellent sound quality.
XMOS XU216 USB Interface & Two High-Quality Toroidal Transformers
Equipped with XMOS XU216 USB audio solution, the GUSTARD R26 can support up to PCM768, DSD512, and MQA 44.1-384kHz. This device also comes with two specific toroidal transformers for audio application and isolated the digital & analog power supply.
