USB input module upgrade: Say goodbye to noise interference, purer signal\u003cbr\u003e- Abandoning the USB 5V power supply, adopting an independent linear power supply with uV level ultra-low ripple linear voltage regulation design, cutting off power noise from the source, making the sound cleaner and the background darker, bidding farewell to the auditory discontinuity caused by noise interference.\u003cbr\u003e- Upgrade two top-notch femtosecond crystal oscillator clocks for NDK, accurately optimize time base accuracy and phase noise performance, significantly reduce jitter, make digital signal transmission more stable and complete, and ensure that every music detail is not lost or blurred, restoring a clear and studio level texture.\u003cbr\u003e\u003cbr\u003e2. Digital input motherboard upgrade: Details are fully loaded, interference is completely cut off\u003cbr\u003e- The Raspberry Pi\/12S input part has been upgraded with an ultra-low ripple regulated power supply architecture, significantly improving power purity and reducing sound quality loss caused by power supply from the source, taking sound resolution to the next level.\u003cbr\u003e- Added support for Raspberry Pi 5! Compared to Pi4, the sound detail resolution has been greatly improved, the instrument separation is clearer, the vocals are more transparent, and it is easy to catch subtle vibrato and breath changes in music.\u003cbr\u003e- Redesign the I2S signal link, with multi-level buffering and impedance optimization processing to further reduce jitter, resulting in smoother signal transmission and more stable sound quality; When not using Bluetooth input, completely cut off the Bluetooth power supply, eliminate Bluetooth RF interference, and ensure that the sound quality is not affected at all.\u003cbr\u003e\u003cbr\u003e3. I2S connection optimization: zero signal crosstalk, more stable transmission\u003cbr\u003e- The I2S signal between the digital motherboard and the motherboard has been upgraded to high-frequency coaxial shielded transmission, with stricter impedance matching and shielding design, effectively reducing signal crosstalk and high-frequency interference, making digital signal transmission more stable and sound quality purer. Even high-frequency details can be accurately restored without distortion or attenuation.\u003cbr\u003e\u003cbr\u003e4. ES9039SPRO DAC module optimization: dynamic filling, details fully displayed\u003cbr\u003e- Equipped with the flagship ES9039SPRO DAC chip, the multi-level filtering and multi-level ultra-low ripple linear stable power supply architecture are upgraded on this basis, providing a purer working environment for the chip and fully unleashing its potential. Added clock buffering and shaping circuit, combined with femtosecond clock for NDK, further improves I2S signal quality, reduces time base error, significantly increases dynamic range, and maximizes music micro detail resolution. Whether it is the grandeur of symphonies or the delicate emotions of vocals, they can be accurately reproduced, with clear layers, full and three-dimensional, as if listening on-site.\u003cbr\u003e\u003cbr\u003e5. Comprehensive motherboard upgrade: combining courage and analysis, suitable for multiple scenarios\u003cbr\u003e- Customized multi-level linear voltage regulation and multi-level filtering architecture for DAC modules to achieve purer analog output, making the sound more transparent and natural, bidding farewell to dryness and stiffness.\u003cbr\u003e- The electronic tube analog output circuit has been comprehensively reformed, and the circuit architecture has been re optimized. Under the condition of no global negative feedback, the THD (total harmonic distortion) has been reduced to 0.05%! It can retain the unique warm and moist taste and natural harmonic structure of electronic tubes, while achieving better linearity and control. The human voice is more delicate, the low frequency is more solid, and listening for a long time is not tiring.\u003cbr\u003e- Both RCA and XLR outputs support adjustable gain from 0 to +6DB. When playing back low-level recordings (especially symphonies), the sound is fuller and more dynamic, making it easy to handle various music styles and not afraid of complex track tests.\u003cbr\u003e\u003cbr\u003e6.
