  1. Let no noise go unsilenced If you think of mains power as the ‘gasoline’ fuelling your audio system, the AC iPurifier is the product that ensures that it’s getting a clean, super premium blend to deliver the best possible audio fidelity. The AC iPurifier is the latest in iFi audio’s stable of ‘power products’ designed to clean-up noisy mains supplies to audio systems. But this is no ordinary mains purifier. Technologically advanced, it’s Active Noise Cancellation (ANC) circuitry can eliminate far more noise across the frequency range than other passive devices. At -40dB, the difference is as distinct as night and day. The following diagram depicts the placement of three AC iPurifiers in one system. Insert AC iPurifier (1) into the shared mains wall outlet. Place AC iPurifier (2) at the first entry point. A third AC iPurifier (3) is best located in-between the two types of power supplies. We recommend that all linear power supplies are located after the AC iPurifier (2) but before AC iPurifier (3). Then all SMPS power supplies are located after AC iPurifier (3). Also, the digital and analogue power sources should be in their respective groups as shown in the diagram. Specifications: Noise Reduction: >40dB (> 100x) Surge Protection: max. 30,000A @ 1,000V/10uS Operating Voltage: 90V – 265V Size/Weight: (USA) 40mm x 105mm (L) 108 (g) / 0.24 (lbs) (EU) 40mm x 115mm (L) 126 (g) / 0.28 (lbs) The retail price of the AC iPurifier is US$99 (ex-tax) or €109 /£99 (incl. tax). Next in line are AC iPurifier technical notes, hence stay tuned!
  2. The friendly tech note… The EarBuddy gets rid of hiss and buzz and improves audio quality. It works on the same principals as the iFi audio iEMatch released in 2016 but its functionality has been adapted to suit a wider audience. Its complex name is an ‘attenuator’ which just actually means a device which reduces the strength of an audio signal. For those of you into the mysterious technological workings of the iEMatch, you can find out more in the Tech Notes at https://ifi-audio.com/wp-content/uploads/data/iEMatch-Tech-Notes(June17).pdf However, if you like the background tech stuff, but not quite as much as some of us, then read on. And if you are a newbie, just joining the iFi revolution, these quick explanations might help! Bits In digital audio using pulse-code modulation (PCM), bit depth is the number of bits of information in each sample, and it directly corresponds to the resolution of each sample - imagine pixels on a computer screen or pieces in a jigsaw. 16Bit audio CDs have digital audio that has a bit depth of 16Bits and a sample rate of 44.1 kHz. Dynamic range In music, this is the difference between the quietest and loudest volume of an instrument, part or piece of music. EarBuddy regains what the (digital) volume loses Basically, a smart device like your iPhone or tablet or a DAP (Digital Audio Player), uses a digital volume control and most of us typically use just 60% of the available volume. On most headphones or IEMs (in-ear monitors) any louder than 60% would blow your head off. And it normally increases annoying background noise in the form of hisses or hums. The trouble with this is that you are not getting the sound quality that you expect/deserve. Dynamic range is effected so the distinction between the quietest and loudest parts of the music is blurred. And resolution is distorted – it’s like a jigsaw puzzle with missing pieces – you just don’t get the complete picture. In an everyday context… If you are streaming music via Tidal or Spotify, you pay for and expect to be listening to music at 16Bits – CD like quality. What actually happens, because you aren’t listening at optimum volume, is that you lose 2Bits of resolution, so you are only listening to 14Bits – less than CD quality. Now, add in the EarBuddy and crank up the volume. The EarBuddy ‘moderates’ the digital volume with an adjustment of -15dB. And at same time gets rid of annoying hisses or buzzes. Effectively, you are allow your device to run at a higher volume without going deaf! You immediately get the 2Bits back and benefit from better resolution and an increased dynamic range, vocals may seem clearer and background hiss has disappeared. It’s a bit of iFi magic. Give the EarBuddy a try and get your Bits back. The retail price of the Ear Buddy is US$20 (ex-tax) or €24 /£20 (incl. VAT)

  4. Hello everyone, I would like the discuss chaining the above equipments. Has anyone tried that already? I would like to replace my hq player naa with the sMS-200.
  5. iDEFENDER3.0 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. Specifications: Super-Speed USB3.0 (and USB2.0 backwards compatible) Connectors: USB3.0 gold-plated connectors Dimensions: 48 (l) x 18 (w) x 8 mm (h) Weight: 6.5g (0.23oz) Warranty period: 12 months The EU retail price: €49 incl VAT The US retail price: $45 ex-tax

  9. iEMatch What the $^ heck is it? We thank you all for your patience and for entering the competition. But besides DUke40, none of the answers were close to being correct - and Duke 40 already won over at Head-Fi. Nevertheless, we thoroughly enjoyed running the competition. Thank you all for entering. The iEMatch 1) What is this new product? Where is it used? iEMatch - it is inserted between the Source and the Headphones/IEMs. 2) What is the first button for – the one on the main barrel (on the left)? Getting rid of the HISS and excessive LOUDness. From mismatched source amplification and headphones. 3) What is the second button for – the one on the 3.5mm connector (on the right)? Selection of Single-Ended (TRS) or Balanced (TRRS). This is a connector proposed by iFi audio to make life simpler with SE or Balanced operation on the go. (More on this later). Why did we develop the iEMatch? The following series of technical notes outlines why we have brought this product to market. We hope you enjoy reading them. Too LOUD, too much HISS? (Part 1) Headphone/IEM mismatched Nearly every High-End Headphones/In-Ear-Monitors(IEM) user has encountered one of the following scenarios. When the headphones/IEMs are connected to the: inflight entertainment system smartphone A/V Amp, HiFi System or dedicated headphone amplifier the volume is at the lowest setting but it is still TOO LOUD and between songs there is a LOT of HISS. This is a mismatch between the Headphones or In-Ear-Monitors and your audio source. Now one can of course sell the new Headphones or IEMs and buy some that are a better match, except many modern Headphones and IEMs are designed with a very large (around 10 times/20dB) mismatch built-in. Instead, one can simply add the iEMatch® in line with your IEM’s or Headphones and adjust for the best match with your source. How bad a mismatch do I have? Background Let us take some numbers for sound levels. [TABLE=width: 100%] [TR] [TD=colspan: 2] Noise/Sound levels[/TD] [/TR] [TR] [TD] Jet takeoff (50m)[/TD] [TD] 140dB[/TD] [/TR] [TR] [TD] Thunderclap[/TD] [TD] 130dB (Threshold of pain)[/TD] [/TR] [TR] [TD] Auto horn (1m)[/TD] [TD] 120dB[/TD] [/TR] [TR] [TD] Chainsaw (1m)[/TD] [TD] 110dB[/TD] [/TR] [TR] [TD] Loud Rock Concert[/TD] [TD] 105dB[/TD] [/TR] [/TABLE] # sustained exposure >95dB may result in permanent hearing loss Due to the risk of hearing damage it is not advisable to exceed 95dB average SPL and around 115dB peak sound levels. Mismatch If we use an iPhone set to maximum (appx. 0.8…1V) and a common HiFi system or in-flight entertainment system (appx 8V) and play music with peaks at the digital maximum, how does a small sample of high-end Headphones and IEMs fare (2)? * at Ultra sensitivity setting [TABLE=width: 113] [TR] [TD] Mismatch[/TD] [/TR] [TR] [TD] Acceptable[/TD] [/TR] [TR] [TD] Good Match[/TD] [/TR] [/TABLE] Red (>116dB) is ‘WAY TOO LOUD,’ which means you have a jet taking off or a thunderclap right beside your ears, which is the majority of the headphones sampled fall into. Amber (113 - 116dB) is borderline. Green (<= 112dB) is fine. The loudest headphone (actually an IEM) is a whopping 30dB or eight times as loud as a standard airline headphone. No wonder it will blow one’s head off even at the lowest volume setting on in-flight entertainment. And with a good headphone amplifier or HiFi system it will produce an unbelievable 155dB, never mind irreversible hearing damage, at those SPL’s tissue in the human ear begins to die off!! (yes, hearing is permanently destroyed). In addition to irreversible hearing damage, having mismatched headphones/iEMs mean that the annoying background noise (hiss) is significantly amplified and affects the enjoyment of music. Solution Most headphones can be matched into the ‘green’ range for comfortable listening using iEMatch® with one of the two settings or at least be brought much closer.
  10. The iDAC2 – spilling the secret sauce (part 1) The iDAC2’s musicality has wooed – most recently the iDAC2 + iPurifier2 + Pro iCAN at the Fujiya AVIC Headphone Festival in Tokyo where the market is probably the most demanding on the planet. Source: iFi Retro Stereo 50 + iPurifier2 at Fujiya Avic 2015 | DAR__KO The Pro iCAN was one of the show ‘best sound winners’ so the small but mighty iDAC2 + iPurifier 2 combo deserve some credit for producing the digital-to-analogue conversion to feed the Pro iCAN. At the show, the quite technically proficient Japanese press asked us on more than one occasion why the recently-launched iDAC2 sounded so nice. And this is a press pack that has turntables in heavy rotation so they know their onions. This gave us the idea to put finger to keyboard. Source: 【候補多すぎ】ヘッドフォンç¥*アワード2015秋は週末までに公開致します! | 目福耳福 Fujiya Avic BLOG Bake-Off: the iFi recipe behind a really good DAC The following are our thoughts only. The application of the parts budget as common industry practice is similar to what we did in the iFi iDSD nano which is more indicative of <US$1,000 DACs. Often a very large part of the budget is needed for the digital platform (after all, we need a DAC Chip that headlines and a good USB processor). Power supplies and analogue stages receive the remaining budget. Hence, the three key cost areas in the electronics of a digital-to-analogue converter: Digital section cost - is much the same across the board, chipsets/clocks vary but slightly and software is usually ‘off the shelf’ like the XMOS firmware and off the shelf DAC Chips of usually comparable cost. In a USB DAC the USB Processor is usually the biggest ticket item before the DAC. Clocks and their power supplies often cost as much as a DAC Chip. Analogue section cost – from a simple double Op-Amp for 20 cent to things done much more extensively cost varies. The iDAC2 has BB Soundplus integrated amplifier and a discrete JFet and BJT Class A output stage. Further it employs C0G Capacitors and MELF Resistors for all signal positions, all this adds cost. Power supply section cost – Often USB DACs have minimal power supply arrangements with generic 3-pin regulators. If done more extensively, then the cost is higher eg iDAC2 uses ELNA Silmic Capacitors and Active Noise Cancellation® to eliminate the USB power noise. iDAC2 is no piece of cake Things are different in the iDAC 2: we started with a larger budget, we could have spent it in a number of ways, like more DAC Chips or different ‘fashionable’ DAC Chips or fancy clocks. Instead we chose to put the extra budget where it impacts most, namely analogue stages and power supplies. The iDAC2 has a similar cost digital section as with other DACs out there (and to our iDSD nano) but its analogue and power sections are more extensive hence its overall cost is greater so its pie chart area is larger. The proof is in the listening. Next time: Part 2. The Digital section
