UIP | オーディオ用USB 2.0電気絶縁アイソレーター

I put this between my laptop running Audirvana and my DAC which was already galvanically isolated, and it made a nice difference. It's hard to verbalize but things sounded more at ease which I assume are improvements in the imaging.

I'm thrilled, the music started to sound divine.LHY UIP,Gustard U18, Audio-GD R-27,OCK-2S

Delivered in a beautiful box with a personal letter, the LHY USB makes an immediately positive impression — and the performance confirms it.
Between my iFi ZEN Stream and the Ayazi Mk2 DAC, it lowers noise, improves timing, and gives the DAC a cleaner, more stable signal.

The result is tighter bass, more micro-detail, and a noticeably calmer presentation.

A clear recommendation.
