How does the SU-1 restructure the wiring logic of a USB audio system?

Ever been there — streamer, computer, phone all crammed together, crawling under the desk just to switch USB cables? And after all that, background noise still creeps in from their power supplies.

The SU-1 solves these small but annoying problems.

Connect once, forget the cables. Three inputs (two Type-B, one Type-C) and two Type-A outputs. Short press to switch sources, long press to switch DACs. No more memorizing ports, no more wear and tear from constant plugging.

Up to 8 meters total cable length. Long USB cables usually mean signal loss, so gear gets stuck in one messy pile. The SU-1 optimizes impedance, letting you spread things out — streamer on the rack, computer and DAC on the desk. Finally, a Hi-Fi system that sounds good and looks good.

Clean power from the output side. Computer and phone USB ports carry noise that degrades your sound quality. The SU-1 uses a fully potted toroidal transformer linear supply with ultra-low-noise regulators, delivering up to 1000mA of clean, stable 5V USB power. Built-in overload protection automatically shuts off during shorts or overcurrent — protecting your gear so you can relax and listen.

When cables and noise stop getting in the way, only the music remains.
