    The central characteristic of iFi is in pursuit of the zenith in audio performance: it leaves no stone unturned. Well, the all new iPOWER is an exemplary example of this. Despite the fact that the iFi Ultra-Low Noise AC/DC adapter was exceptionally quiet and elevated the iUSB and iPhono to punch way beyond their respective categories, the all new iPower is even quieter, up to 10x quieter in fact.


    What is it? Brand new audiophile-standard DC-power supply: In 5V, 9V, 12V and even 15V versions.


    Which products is it aimed at? Virtually any DC powered device. Just check the correct voltage (5V/9V/12V/15V). Check the correct polarity setup. Ensure the current output is sufficient, then plug in and enjoy.


    Three years ago, iFi's Ultra-Low Noise AC/DC power adapter set the way and underpinned the whole iFi range from the iUSB to the iPhono leading to their loyal following.


    Well, not to rest on its laurels, iFi now has a completely new 'ground-up' DC powered supply.


    Drawing from the military field (specifically the Thales Spectra radar cancellation system deployed in the French Dassault Rafale jet fighter), iFi adapted this technology to exclusively introduce the Active Noise Cancellation+ ® (ANC+®) audio power system. It is so good ANC technology is now a cornerstone of the ever-improving iFi USB audio technology range.


    By generating a signal identical to the noise signal but in the exact opposite phase, it actively cancels all the incoming noise. ANC+® is the perfect 'antidote' for power supply noise, the bane of USB audio.


    With ANC+® the power line is filtered for audio band and RF noise. The measured noise floor of 1uV (0.000001V) is at the measurement limit of what even the most sophisticated Audio Precision equipment is capable of.


    Measured on the Audio Precision 2, the iPower has an astonishingly low audio band noise floor of just 1uV! To put this into context, iFi's very own Ultra-Low Noise AC/DC adapter was in a class of its own at 10uV. Compared to a typical audiophile Linear Power Supply which measured at 20uV, it is demonstrably clear AMR/iFi power supply technology is unparalleled.


    Shaping the face of technology, AMR/iFi not only pushes the boundaries of audio design, but power design too. After all, electricity is the 'fuel' behind the audio signal.
    There are two separate, but similar 'Array Technologies' in the iPOWER:


    • 12-Element Output Array - is for addressing noise on the output (at the DC barrel) end.
    • 6-Element Input Array - is for dealing with noise at the input (at the 2-pin mains) end.

    What this means is that any noise is contained and neutralized with the iPOWER to halt it from contaminating the local mains or audio system. iFi is one of a handful of companies that manufacture 'battery quiet' DC power supplies. Just like hybrid technology in cars, both have come a long way in a short space of time and are gaining wider acceptance.


    At iFi, we like to think comprehensively and while the majority of home and pro audio products have a 'centre positive' DC power connector type, if your product such as a guitar pedal or a Sony Discman has a 'centre negative' instead of 'centre positive' pin, it is important to use the iFi power inverter. If you are unsure of the DC polarity of your product, please check with your vendor. For equipment using a DC power connection, it is common practice to include protection circuitry against over-voltage/reverse polarity, but not every manufacturer will have applied this. Always check first as AMR/iFi is not responsible for incorrect use or damage arising from use of the iPower.


    AMR/iFi understands and appreciates that today, being portable and user-friendly is paramount. So the iPower is light, convenient and above all, easy to travel with and work in any country in the world. It comes in 5V, 9V ,12V and 15V versions for all manners of DC powered devices and a set of interchangeable pins to span the globe: for USA/UK/EU/AUS electrical outlets. Performance and portability personified.


    In summary, all the technology behind the iPower would count for little if it was not audible. Well, it is both. With the all-new iPower, the noise floor is virtually inaudible and the all-important level of refinement (whether listening to an analogue or digital source) has been amplified several notches.


    Best of all, all existing iFi-powered devices all benefit, and in the different DC-power versions, the iPower now compliments non-iFi DC-powered products too. So all can enjoy the "sound of iFi."


    The USB power line runs on 5v and the Raspberry Pi/Cubox/BeagleBone (or similar Microcomputer) is rapidly becoming the most popular computer server option. So, each iPOWER (5v version ONLY) ships with the DC > micro USB cable so that the iPOWER (5v) can supply pure, clean power to the microcomputer for the optimal computer audio playback.

    iFi Audio SPDIF iPurifier


    Have a question about this product? Please email our audio advisor or call 1-877-929-8729 with any questions or concerns regarding your equipment purchase.


    The SPDIF iPurifier is partly a nod to past SPDIF devices including the Genesis Digital Lense. With the very latest AMR/iFI technology, it is suited to the gamut of SPDIF sources that are on the market today. It takes any barely recognisable 'square wave' and with REclock/REgenerate the signal is back to a real-world, perfect wave form.


    From Apple TV to Google Chromecast to PS4/Xbox to 4K Smart TVs, SPDIF is the main digital audio output. As with all mainstream products, the critical SPDIF signal transmitted is of fairly low quality. The SPDIF iPurifier runs the SPDIF signal through 4 comprehensive stages, and the result is a fully-restored, perfect SPDIF with jitter eliminated. The result is sound quality that has greater warmth, resolution and dynamic contrast.


    Restoring the Waveform and eliminates all jitter


    The signal from SPDIF devices is a digital signal. The industry standard for looking at the quality of a digital signal is to look at the 'square wave' (on an oscilloscope).


    But the wave is anything but 'square', resembling more of a jagged wave. By running through the four major stages of the SPDIF iPurifier, the Waveform is back to ideal.


    Bit-Perfect audio on all fronts


    AMR/iFi prides itself in assuring Bit-Perfect signal transfer. This means the signal remains original and unchanged. The SPDIF iPurifier ensures a Bit-Perfect transfer which is highly unusual for SPDIF devices. It can handle 44.1 / 48 / 88.2 / 96 / 176.4 / 192kHz; 16 to 24 Bit, DSD/DoP, and even Dolby Digital and DTS.
    The SPDIF iPurifier has co-axial/optical input AND co-axial/optical output. It works with just about any and every SPDIF product from mass market Apple TV to an audiophile transport > DAC.


    Galvanic isolation


    The SPDIF iPurifier has no peer. One of the key aspects is that it has galvanic isolation which uncommon. It was however found in the original Digital Lense which retailed at US$1,800 in 1996.


    Galvanic isolation is converting a signal from one form to another which will discard spurious noise. This is a major factor behind the SPDIF iPurifier's ability to stop noise contaminating the signal.


    Global Master Timing® + Memory Buffer


    AMR's Global Master Timing (GMT)/ Memory Buffer System represents a total 'out of the box' systematic digital solution that solves the digital SPDIF jitter issue once and for all. The Intelligent Memory System holds a large number of complete audio samples, so it may completely absorb a large amount of variation (jitter and drift) in the incoming signal, while still sending out data at a fixed and precise clock rate, regardless of variations in the incoming clock.


    Central to the GMT clock system is an ultra-low jitter, quartz-driven clock system (<300 femto second crystal) capable of producing millions of different frequencies with a precision of better than 0.001Hz. Hence, if the frequency shifts from 192,000.002Hz to 192,000.003Hz over a period of minutes (drift) which is the minimum to be meaningful, the GMT clock will intelligently and precisely track the change. This is a core technology of the SPDIF iPurifier.


    iPower 'quieter than battery' technology


    As the SPDIF iPurifier is powered by 5V, it is essential that it is fed by silent power supply. Hence each and every SPDIF iPurifier is shipped with its own iPower (5V). With a noise floor that of 1uV, the iPower is a breed of near silent DC-power supply. Low power consumption and low-noise.


    Packed to the brim


    With a Bill of Materials (BOM) that stands at 53 individual components, be assured that beneath its unassuming exterior, there are two separate PCBs, each mil-spec'd and packed to the brim with advanced technology.

    iFi Audio iDefender3.0


    Have a question about this product? Please email our audio advisor or call 1-877-929-8729 with any questions or concerns regarding your equipment purchase.


    The iDefender3.0® protects against the common problems of ground loop noise and noisy USB power:


    • Breaks noisy ground-loops. Significantly reduces system noise floor and makes for better dynamic contrast, warmth and resolution
    • Disconnects the USB Power from the PC and replaces it with a clean external power (optional iPower* 5V for ultra low noise)
    • USB3.0 port technology - most advanced and highest USB specification

    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.


    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.


    For DACs 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.


    As the iDefender3.0® breaks the noisy power supply, this is for DACs with an internally-powered USB line.


    But for DACs that require use USB Power, a separate 'micro port' power connection is provided for a 5V DC supply. Any 5v power supply can be used. Though we recommend the almost silent 1uV noise floor of the iPower®. It 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' to downstream devices and 'leaked' back out to nearby components.


    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 e.g. the wire gauge specification is more exhaustive and the connections are better.
