2<\/b>\u00a0.\u00a0Like its predecessor, it is a balanced R2R DAC based on discrete resistor networks.\u00a0Additionally, it operates in NOS (Non-Over-Sampling) mode for very clean, authentic signal restitution.\u00a0Here are the main improvements in the second version of the CYAN DAC:<\/p>\n<ul>\n<li data-xf-list-type=\"ul\">It is equipped with two independent R2R networks, the first of which performs the primary DA conversion of PCM streams, and the second (with a vector step) performs the DA conversion of DSD streams.<\/li>\n<li data-xf-list-type=\"ul\">New, more efficient deglittering technology has been integrated.\u00a0It does not create any unwanted noise or effects.<\/li>\n<li data-xf-list-type=\"ul\">CYAN 2 has the best performance: SINAD over 106 dB and dynamic range over 127 dB.<\/li>\n<li data-xf-list-type=\"ul\">It now supports sample rates up to PCM 32bit 1536Mhz and native DSD up to DSD1024 via USB.<\/li>\n<li data-xf-list-type=\"ul\">The USB interface uses proprietary software with ultra-low latency and data transfer reliability 2-4 times higher than conventional interfaces on the market.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><img loading=\"lazy\"
