The Linear error is small, the decoding speed is high, and the digital noise is Low. It not only ensures low distortion of the audio signal but also ensures very low background noise music.   \n\n  \n\n \n\n\n  \n\n  \n\n Self-Developed Technology   \n\n Make the sound more outstanding \n\nUsing self-developed and designed digital filters, working in 16 X Over Sampling mode, each Level of filter has a 32-bit input resolution, which can greatly increase dynamic contrast, analysis, and more natural and delicate timbre, etc.   \n\n  \n\n  \n\n\n  \n\n  \n\n Tailored for the sound   \n\n Using the main control ALTERA high-efficiency chip, the audio signal transmission is not distorted and the sound quality can reach the HIFI standard hardware. The simple design makes the signal circuit reach a more ideal state, and the sense of hearing is clearer and more balanced than the traditional design.   \n\n  \n\n \n\n\n  \n\n  \n\n Warm Tips   \n\n The burn-in time of Aquarius DACs is one week: Standby or Powered on 24/7 (300 hours), you will get the best performance after the enough aging hours.   \n\n  \n\nConnecting RCA or XLR output simultaneously is not recommended, it will degrade the sound quality because they are shared. Even if the downstream equipment is on/off, the output signal will still be transmitted to the input stage of the downstream device.   \n\n  \n\nIf possible, please use the XLR output. As a true balanced DAC, the XLR output of Draco will be more superior.   \n\n  \n\n  \n\n  \n\n  \n\n  \n\n ","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/products/MusicianAquarius-2-800.jpg?v=1632826545","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/MusicianAquarius-1-800.jpg?v=1632826546","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/MusicianAquarius-3-800.jpg?v=1632826545"],"price":3199.99,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:47.703Z"},"share_url":"https://firestarter.network/l/lst_g3qjf5QQ","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
