The GUSTARD R26 Discrete R2R Decoder Native DSD DAC with Streamer/Renderer is a high-end audio device that provides a more natural sound by using a discrete R-2R ladder DAC architecture. It supports native PCM and native DSD up to DSD512 (via USB) and DSD1024 (via IIS). The DSD stream is decoded by an independent 1-bit converter without DSD to PCM converting. The device also features a Complex Programmable Logic Device (CPLD) that provides signal routing, clock management, 2nd order PLL, DOP decoding, and depop for PCM&DSD. The clock synthesizer replaces the input signal's clock with precision oscillators (local or external) to avoid interference from the input source's clock. The device has several functions that can be turned off such as IIs, AES, COAX, OPT, BT; PCM NOS, 1 Bit. It also has several functions that can be turned on such as USB & LAN K2 ultra-low noise clock synthesizer which provides precision clock from local oscillators or external clock in.
The 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. However, the parasitic effects introduced huge challenges to development experience and device's quality.
Features:
Discrete R2R DAC: R-2R ladder DAC converts the digital signal to analog signal by switching resistors' array, it provides a more natural sound. However, this architecture needs precision resistors and deep development to archieve fine performance.
Native 1Bit DAC:support DSD 512 (via USB) and DSD 1024 (via IIS). The DSD streamdecoded by the independent 1 bit convertor without DSD to PCM converting.*Volume is fixed under this mode.
CPLD: Complex Programmable Logic Device：Signal routing; Clock management; 2nd order PLL; DOP decoding; Depop for PCM&DSD.
Clock synthesization: Replace the input signal' s clock with precision oscillators (local or external). Interference from the input source' s clock is avoided. Function off: IIs, AES, COAX, OPT, BT; PCM NOS, 1 Bit Function on: USB & LAN K2, ultra-low noise clock synthesizer: provides precision clock from local oscillators or external clock in.

Thank you for shopping with thehificat.com. Please read our shipping policy carefully before placing your order.
In accordance with the latest EU Council regulations and customs guidelines, a new tariff system will take effect across all 27 EU member states (Austria, Belgium, Bulgaria, Cyprus, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden) starting 1 July 2026.
Key Policy Change: The EU is abolishing the previous duty exemption for low-value parcels. From 1 July 2026, all goods declared through IOSS with a value not exceeding €150 will be subject to a fixed customs duty of €3 per HS tariff code category. All goods entering the EU — regardless of value — will now be subject to customs duties.
To ensure smooth customs clearance and transparent cost management, a handling surcharge of USD $5 has been applied to all standard shipments to EU countries (orders under $500). For orders over USD $500, expedited shipping remains complimentary.
