USB is one of the most widely used interfaces, however it is not optimized for audio applications. Signal quality will often be compromised by length cables, ground (earth) loops, and power supply and system noise, such as RFI/EMI. The iGalvanic3.0 eliminates all of the above through: -Galvanic Isolation USB 3.0 and USB 2.0 - ONLY the signal passed between the computer and the HiFi audio system. -REgen - Double regeneration for perfect signal quality and integrity. -Galvanic isolated power supply quiter than Linear Power Supply (LPS) at 0.5 uV The iGalvanic3.0 delivers the ideal solution to break ground loops, avoiding noise coupling and providing the best USB signal possible in applications that require hi speed USB transfers. It will bring maximum sound quality from the USB digital audio devices regardless of source, both for computer audiophiles and recording studios alike.
