{"type":"firestarter.listing","listing":{"id":"lst_fhOJLcGI","product_name":"Musician Pisces II","category":"AMP & DAC","description":"\n\n\nProprietary USB interface based on advanced AMR MCU\nARM STM32F446's proprietary USB audio solution is based on the advanced AMR MCU, which facilitates high-performance and high-precision signal processing tasks, such as audio processing, power management, and sensor data processing. The redesigned and optimized circuit enables the utilization of DDC in high-end DDC and computer applications. Moreover, the solution includes an authorized thesycon USB Windows platform driver, guaranteeing seamless compatibility and reliable performance. It supports 24-bit/768kHz PCM data flow and DSD local processing up to DSD1024. AMR MCUs are widely used for various applications due to their integration of digital and analog functionalities. They excel in tasks that demand precise signal processing and can effectively replace traditional purely digital or analog signal processors in certain scenarios, enhancing overall system performance and efficiency.\n\n\n\n\n\nDual FEMTO Clock Technology\nPisces is equipped with a dual FEMTO clock, powered by an O-type transformer to ensure stability, linearity, and femtosecond clock output frequency. Its high reliability provides stable and low phase noise frequency signals, resulting in more accurate signal regeneration, realistic details, and a smooth, natural sound.\n\n\n\n\n\nTemperature Compensated Active Crystal Oscillator\nPisces incorporates a temperature compensated active crystal oscillator, a cutting-edge technology that ensures precise and stable frequency performance. The temperature compensated crystal oscillator automatically adjusts the external matching capacitance matrix based on temperature measurements, resulting in highly accurate and stable frequency output.\n\n\n\n\n\nEnhancing Sound Quality with Pisces Isolation Buffer\nThe Pisces isolation buffer utilizes a FEMTO crystal oscillator to retime the USB input data, resulting in a low jitter digital output that can be connected to any external DAC. This transforms the computer audio system in","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/files/IMG_7019.jpg?v=1704880400","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/IMG_1567.jpg?v=1704880400","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/IMG_1558.jpg?v=1704880400","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/IMG_1558_7f7b04ab-7eba-46bb-ae51-7f7c05aae44c.jpg?v=1704880399","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/IMG_1563.jpg?v=1704880398","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/IMG_1564.jpg?v=1704880399"],"price":519,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:46.873Z"},"share_url":"https://firestarter.network/l/lst_fhOJLcGI","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
