Gustard A26 MQA Decoder Dual AK4499EX & AK4191 Support DSD512 PCM768K MQA384K DAC-A26 with Streamer/Renderer (33 * 26 * 6.5cm, Black, 1)

Description

• AK4499EX 2:Two AK4499EX DACS and one AK4191 modulator from Asahi Kasei Microdevices.With independent power supply and grounding for each channel, separate digital-analog architecture eliminates interferences from the beginning
• Streamer /Renderer: Easy access to high-quality online streams. Roon, UPnP and HQPlayer NAA are supported at present, and there will be more protocols in the future.
• CIock synthesization: Replace the input signal' s clock with precision oscillators (local or external). Interference from the input source' S clock is avoided.
• K2, ultra-low noise clock synthesizer: Provides precision clock from local oscillators or external clock in.
• LPF:LPF is specifically designed for the AK4499EX 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.
