Hello guys, I am selling a DIY Streamer kit based on Raspberry Pi 4. Please be noted that soldering and assembly are needed (except SMD components). Please also note that the currency is in HK dollar (1 USD = 7.8 HKD). Can ship internationally. Shipping fee incurred depending on destinations.
Powered by three individual LPS, and galvanically isolated from the touchscreen and the Ethernet, STEALTH V3 delivers extremely quiet background, detailed and lively music experience. Among the three LPS, one of them can be configured as an internal power (5V/1A) for OCXO clock, digital / DAC HAT, etc. Or externally for USB devices (5V/1A) such as USB DAC and SSD/HDD. What’s more, it can also be configured as a power supply for an external device up to 15V/1A (to be negotiated).
When configured as an external USB power, the attached USB device is powered separately by this LPS, and the ground is separated from the Pi 4 with a tailor-made 45mH ground choke. The choke can prevent high frequency noise from flowing into the attached USB device from Pi 4 and vice versa. Additionally, the galvanically isolated Ethernet connection prevents common-mode noise from polluting Pi 4 and degrading sound quality. In fact, the Ethernet isolator works better than an electrical – optical converter, it improves the sound quality with darker background, clearer bass, smoother highs and better separation between instruments.
In short, STEALTH V3 = music server + streamer + player + audiophile switch
