Part 1: iFi Audio iGalvanic3.0 - The Holy Grail of Audio In “The Last Crusade” in a cavern full of cups, Indiana Jones had to choose the Holy Chalice used in the last supper. In USB audio, similar propositions are abound as selecting the best device to improve USB computer audio presents a mind-boggling array of choices. It is widely regarded that one of the most effective USB solutions is galvanic isolation. However, its scarcity reflects the technological hurdles that are not without difficulty. Having spent the best part of two years researching, (hence why we did not bring it out earlier!), we wholeheartedly agree. The iGalvanic3.0 has been one of our more ‘technically challenging’ projects. But the team at iFi Audio are NOW over the moon to announce the iGalvanic3.0. It is one of a kind - able to deliver galvanic isolation on USB3.0 Super Speed. In a sea of USB audio improvement devices, the iGalvanic3.0 really is the ‘holy grail.’ We could have stopped work there and just brought the product to market. Yet, this is not in the AMR/iFi DNA. From this starting point, we invested more time to develop additional features that truly make this product the ultimate solution for USB computer audio. We believe the iGalvanic3.0 will elevate the quality of the audio playback by an order of extreme magnitude. What is the iGalvanic3.0? The iGalavnic3.0 is the one-stop USB audio enhancement solution for every computer audiophile. It offers the USB Trinity of: Audiophile-grade galvanic isolation REclock2/REgenerate2/REbalance2 Clean USB power supply*. *Measured noise is 0.5uV(0.0000005V) @ 500mA load. Outclasses non-iFi USB devices. Bettered only by the micro iUSB3.0. It is a ground-up, dedicated, stand-alone solution that elevates just about every computer audio system. Who benefits from the iGalvanic3.0? Everyone who uses USB for computer audio. More specifically, the iGalvanic3.0 is the ideal solution to: Break ground loops Avoid noise-coupling in applications that require hi-speed USB transfers. Thus, the iGalvanic3.0 is the perfect solution for computer audiophiles through to recording studios seeking maximum sound quality from their USB digital audio system. Stay tuned, next section coming soon! Part #2 High-Tech & High Spec.
iDefender3.0 (Official) - USB Ground Loop Eliminator
AMR/iFi audio posted a topic in General ForumiDEFENDER3.0 The iDEFENDER3.0 solves the common ground loop/hum. It ‘breaks’ the ground loop but in a, proper and electrically safe way Just add iPOWER 5v to inject clean power at the source. Break ground loops the correct way. iDefender3.0 with IsoEarth® Use upstream at the audio source. Because USB is bi-directional. Latest USB3.0 standard. For optimum performance. Cut-off noisy power. Inject pure, clean iPOWER 5v. The iDefender3.0 protects against the common problems of ground loop noise and noisy USB power (if used with optional external iPower 5V). As USB is bi-directional, it is important to address noise issues upstream as well as downstream. Common USB noise problems addressed by the iDefender are: [*=center]Breaks noisy ground-loops. Significantly reduces system noise floor and makes for better dynamic contrast, warmth and resolution [*=center]Disconnects the USB Power from the PC and replaces it with a clean external power (optional iPower* 5V for ultra low noise) [*=center]USB3.0 port technology – most advanced and highest USB specification The iDefender, just like its iUSB power sibling, brings usb port noise at the computer from a typical 100uV down to 1uV. So a 100x reduction that is quieter than a 9v battery. Beneath the compact exterior, the iDefender is feature-rich, with the latest iFi technology. To be used directly at the Source such as the PC usb port, it breaks ground loops and cuts the noisy USB power line. From computer audiophiles, musicians, home studio artists to pro audio customers, it improves audio playback quality at home and on-the-go. *To obtain the best result, the optional iPower 5V is recommended. USB is bi-directional, pays to look upstream Unlike SPDIF which is directional, even as the USB logo itself illustrates, USB is bi-directional. Therefore, despite more efforts and benefits to looking downstream such as at the DAC end, we believe it is also beneficial to look upstream at the source. The iDefender3.0 solves one quite common issue found with either: 1. Multiple earths 2. No earth That is a ground loop which manifests itself as an audible ‘hum.’ The iDefender3.0 cuts the ground loop AND also offers the ability to inject a clean 5v power supply via the micro USB port at the side. For computer audio enthusiasts to professional recording studio engineers, the iDefender3.0 slves these two issues in one fell swoop. Break the noisy USB power, but in the correct way There are more than a few products that break the USB Power connection, but of the ones known to us, they do very little because the noisy ground connection remains. This is quite a major oversight in our opinion. For DAC's that do not use USB Power (except for handshake) the iDefender3.0 breaks the ground connection eliminating earth loops, while allowing normal handshake operation to continue. So in terms of cutting out the noise, it does it in the most comprehensive way possible while at the same time, in an electrically correct way. USB3.0 technology, at the cutting-edge It is now a hallmark of all the latest iFi signal and power products to be USB3.0 standard. First USB3.0 is backwards compatible with USB2.0. Second, in terms of the specifications, USB3.0 is superior to USB2.0 eg the wire gauge specification is more exhaustive and the connections are better. Need clean power? Inject iPower ‘quieter than battery’ technology As the iDefender3.0 breaks the noisy power supply, this is it for DACs with an internally-powered USB line. But for DAC's that use USB Power a separate power connection is provided to feed in a 5V DC Supply - this is needed to break the ground connection, as long as the DAC tries to draw USB power from the Source instead the ground cannot be isolated. With a noise floor that of 1uV, the iPower is a new-breed of near silent DC-power supply. Low power consumption and low-noise. With 12-Element Array on the output and 6-Element Array technology on the input, there is next to no noise supplied and ‘leaked’ back out to nearby devices.
