Portable Headphones Amplifiers

Devilishly brilliant The iDSD Diablo, with its sleek new design and fiery red finish, sits proudly at the top of our range of portable/transportable DAC/amps. It is built for purists – the true headphone enthusiasts who crave pure, unadulterated sonic performance. Just like a racing car designed for uncompromising speed, the iDSD Diablo sets aside sonic tailoring as well as Bluetooth connectivity to focus on pure sonic power. Prepare for a riveting ride as it will drive any headphone on the planet with aplomb. Put simply, the iDSD Diablo is our best ever transportable amplifier designed to deliver reference level sound. ‘Bit-perfectly’ wicked We use two Burr-Brown DAC chips and the new 16-core XMOS chip to process the data received via the USB and S/PDIF digital inputs. This means the iDSD Diablo can handle up to PCM 768, DSD 512, 2xDXD. Both PCM and DSD remain ‘bit-perfect’. It also provides full MQA decoding! Check out our MQA set-up tutorial (using the highly acclaimed NEO) for Tidal, Roon and Audirvana Positively pure Balanced, differential analogue circuit design reduces noise and cross-talk within the signal path by fully separating the left and right channels. The iDSD Diablo benefits from further refinements to our balanced, symmetrical dual-mono topologies with short, direct signal paths. We call this PureWave. Negative feedback is used in amplifier circuits to compare the output signal with the input signal and correct errors. BUT there are drawbacks. iFi turns the negatives into positives with OptimaLoop. Read more on these technologies below. Diabolically dynamic Able to drive all manner of headphones with ease, the iDSD Diablo delivers up to 5000mW of prodigious power, propulsive energy and engaging dynamics, coupled with a remarkable ability to resolve fine texture and detail. With 3 settings, you can adjust power and gain to suit your daily driver or track day supercar! Turbo – ramps up the level of drive for current-hungry headphones Normal – for most over or on ear headphones Eco – dials down the power to suit high-sensitivity in-ear monitors The iDSD Diablo’s focus on pure, unadulterated performance, means much attention has been applied to the power supply circuity. Battery power provides ultra-clean and stable DC current avoiding the issues of mains electricity – dips, spikes and noise-inducing RFI/EMI pollution. BUT there are sonic downsides resulting from low output voltage and inconsistent output impedance as batteries discharge. These issues are fully tackled by the iDSD Diablo’s design. In order to make less efficient headphones, like planar magnetics, sing, the voltage needs to be stepped up from 3.7V to +/- 15V.  We use a step-up converter running at 1.2MHz – a frequency far beyond audibility that is easier to filter than a typical switch-mode supply, enabling high linearity and ultra-low noise. Formula 1, iFi style. High-bandwidth power supply circuity is dedicated to each critical part of the iDSD Diablo’s design, with independent linear regulation delivering excellent PSRR (Power Supply Rejection Ratio) performance. The headphone amp stage eschews IC regulators in favour of Panasonic OS-CON capacitors, delivering 2320uF between them. The DAC section benefits from an ultra-low-noise regulator with additional passive filtering, reducing high order harmonic distortion and, in turn, jitter. Even the USB input stage benefits from dedicated regulation and multi-stage filtering, and the microprocessor control circuitry (often a local source of digital noise) has separate regulation, too. Hooking up with the Devil… At the front of the unit, alongside a standard 6.3mm single-ended headphone socket, resides a 4.4mm Pentaconn output for headphones offering balanced connection. At the back are two digital audio inputs: USB-A and a S/PDIF socket that accepts both electrical and optical signals, the former via a 3.5mm connector and the latter via a supplied adapter. The USB-A input features a ‘male’ connector, rather than a typical ‘female’ port for greater mechanical integrity.  A separate USB-C charging port is also provided, along with a 4.4mm Pentaconn balanced output to connect to an external amp. Accessories galore As befits a reference-level product, we’ve included a whole host of accessories in a luxurious travel case, the iTraveller. As the iDSD Diablo may be powered from the mains, as well as by its built-in battery, we’ve included our super silent, noise-cancelling iPower 5V AC/DC adapter to ensure optimal sound quality. Also included is a 4.4mm Pentaconn to XLR balanced interconnect cable to connect the iDSD Diablo to an amp and speakers (or a pair of active speakers) with balanced XLR inputs. Other supplied connectors include a high-quality USB-A audio cable, a USB-A to USB-C charging cable and an adapter to connect headphones with a 3.5mm jack to the 6.3mm single-ended output.

Our iDSD Signature Dish Our top-of-the-range desktop/transportable DAC and headphone amp will supercharge your tunes. Out of this world Sporting a Space Blue finish and powered by a built-in rechargeable battery, the micro iDSD Signature is a transportable DAC/headphone amp that’s ready for anything that the universe throws at it. Battery power means it’s ultra-clean with ultra-stable DC power and avoids the pitfalls of AC mains – dips, spike and noise-inducing RFI/EMI pollution. And with up to 12 hours playing time, depending on the headphones and performance mode engaged, it feels like you could take it to the moon and back. Finely tuned Based around two Burr-Brown DAC chips in a custom ‘interleaved’ configuration, the digital engine has four pairs of differential signals – two pairs per channel. This means a lower noise floor improved channel separation finer musical detail and micro-dynamics The micro iDSD Signature handles up to PCM 768, DSD 512, 2xDXD and MQA. All this is done natively. Both PCM and DSD remain ‘bit-perfect’. Precision personified Extensive jitter-eradication technologies are applied to the digital engine, including iFi’s GMT (Global Master Timing) femto-precision clock and the intelligent memory buffer. The micro iDSD Signature also comes with iFi’s GTO (Gibbs Transient Optimized) digital filter installed. And exclusive firmware available on our website means you can change digital filters as you wish. Circuit training With up to 4100mW of power the micro iDSD Signature can drive all manner of headphones with aplomb, from highly sensitive in-ear monitors to current hungry planar headphones. The signal path has been refined to maximise sonic texture. High spec components featuring class-leading qualities such as low ESR (Equivalent Series Resistance), high stability and low distortion mean top-notch sound quality and maximum musical enjoyment. Add in the direct-coupled nature of the circuit – no coupling capacitor is present – and the micro iDSD Signature definitely runs rings around the competition. Versatile sonic tailoring One size no longer fits all when it comes to quality listening. The digital stage of the micro iDSD Signature features a variety of filter settings: ‘Standard’, ‘Minimum Phase’ and ‘Bit-Perfect’ for PCM files ‘Standard Bandwidth’, ‘Extended Bandwidth’ and ‘Extreme Bandwidth’ for DSD The amp stage also has three settings to adjust power and gain. As well as ‘Normal’, you get ‘Turbo’  to ramp up the level of drive for current-hungry headphones ‘Eco’ to dial down the power to suit high-sensitivity in-ear monitors and/or to extend battery life Complete this with our iEMatch technology that adjusts output level and our XBass+ and 3D+ signature sonic tweaks, and the micro iDSD Signature is flexible to the max. Get connected The micro iDSD Signature features two digital audio inputs – USB Type-A and an S/PDIF socket that accepts both electrical, via a 3.5mm connector, and optical signals – adapter supplied. It also houses a pair of RCA analogue outputs to connect to a pair of powered speakers or a power amp to act as a DAC. There is a 6.3mm output for headphones that have a standard single-ended connector (headphones with a 3.5mm jack can be connected using an adapter) and a 4.4mm Pentaconn output for headphones offering balanced connection. Both headphone outputs utilise our ‘S-Balanced’ output circuitry. This delivers the sonic benefits of balanced connections with all headphone/earphone types – even those with single-ended connectors – cutting crosstalk and associated distortion in half. The Burr-Brown True Native chipset means file formats remain unchanged or ‘bit-perfect’. This means you are listening to music as the artist intended in the format in which it was recorded. At iFi we use Burr Brown extensively in our products having selected it for its natural-sounding ‘musicality’ and True Native architecture. Our experience with this IC means we know how to make the most of it. Doubling the DAC chips results in 3dB lower noise floor and better channel separation. Together with power supply advancements and advanced channel interleaving, the noise floor has been halved. All of this equals stellar sonic performance. Hi-res audio support is state-of-the-art with True Native playback. It handles PCM data to 32-bit/768kHz, DSD up to DSD512 and single and double speed DXD. Thanks to the Burr-Brown DAC chip’s four-channel True Native design, PCM and DSD take separate pathways – this enables DSD, as well as PCM, to remain ‘bit-perfect’ in its native form right through to analogue conversion. This is not the case with all DAC devices from other brands – even if DSD compatibility is stated, many such DACs convert DSD signals to PCM. Listen to Master Quality Authenticated audio straight out of the box. Connect to Tidal Masters and check the option to stream MQA. As with many other iFi audio products, we’ve incorporated a custom OV Series operational-amplifier. This top-notch component contributes to the extremely low noise, low distortion (0.0001%) and wide bandwidth. With output power up to 4,100mW, this headphone amplifier drives all headphones with ease. It has 3 power modes – Eco, Normal and Turbo. Power and gain can be dialled-in perfectly to suit ALL headphones. iFi’s exclusive S-Balanced circuit delivers maximum performance from single-ended and balanced headphones alike. 3D+ Holographic delivers an immersive, deep soundstage.  XBass+ delivers a deep, tighter bass sound.  Texas Instruments low-noise ICs offer great unity-gain bandwidth, very low noise and distortion, high output drive capability, Common-mode and Power Supply Rejection Ratios of over 100 dB, wide maximum-output-swing bandwidths and high slew rates. iFi always uses the best components possible.

Power your headphones. Big style. With maximum output power (32R) around 10 times that of iPhone 6 (285mW vs. 27mW), the nano iDSD Black Label can drive most headphones on the market.From In-Ear-Monitors to mid-size headphones, the nano iDSD BL is able to drive them with ease. Below is more background information on the S-Balanced circuit and iEMatch/Normal outputs. Take your headphones to the max. Uber convenientIt’s small, lightweight and battery powered. You can take the nano iDSD Black Label everywhere you go and it won’t drain your phone’s battery.Just switch on the BL first and then plug in your device. The Lithium Polymer battery gives the nano iDSD Black Label up to 10 hours of non-stop musical enjoyment. It also has a special USB male ‘A’ connector for a direct connection. Use a USB-to-Lightning (Apple) or OTG connector (Android). Or if at home, just use the enclosed USB3.0 cable to connect to a PC. Stream Apple Music/Google Play/Spotify/Tidal/Youtube content from your phone to a whole other level of quality. Add kick-a** sound to your gaming by connecting your console or computer. Master Quality AuthenticatediFi always strives to bring you choice. We’ve added yet another file format to our portfolio in the form of MQA in the new BL. Take TIDAL or your MQA file to a whole new level.MQA is an audio technology developed by Bob Stuart. This technology makes hi-res audio streaming a reality and delivers studio master quality audio to your headphones.An original Master file of up to 384kHz/24Bit which has been encoded in MQA, is transmitted as a 48 kHz/24Bit file. At the end of the chain, whether the decoding and rendering takes place in the same device, or whether the process is split between a software application and a separate DAC, the result will still yield the full, original 384kHz/24BIt file. For mobile DACs with both portability and power considerations, MQA Rendering is the ideal solution as the workload is shared between the host (computer) and the client (DAC). In this case, for a DAC such as the nano iDSD BL, less CPU processing and lower electrical power are needed. This approach for the iFi portable range remains a full end-to-end MQA solution and the listener still enjoys the full benefits of MQA without compromise. High-Res Audio CertifiedThe nano iDSD Black Label is one of the best native highest-resolution DACs you can find, supporting PCM up to 32/384 kHz and DSD up to 256 times the sample rate of a CD, even on Mac OSX* and mobile phones*. It is also certified ‘High-Res Audio’ according to the stringent criteria set down by JEITA and JAS (Japan Electronics and Information Technology Industries Association and Japan Audio Society). Don’t accept low-resolution music!(*firmware upgrade needs to be applied to enable DSD256 on all devices) Perfect your listening pleasureThe nano iDSD Black Label lets you choose between the ‘Listen’ (Minimum Phase Bezier Filter) and ‘Measure’ (Linear Phase Transient Aligned Filter) options. It’s the only portable DAC to give you so much control. Compatible. Like no other.The new headphone amplifier delivers more than double the power of the original nano iDSD into 16 Ohm and over four times the power into high-impedance headphones. Meanwhile, the built-in IEMatch circuit ensures that even extremely sensitive headphones and IEMs are ‘hiss free’ throughout the volume range.The nano iDSD Black Label also includes the S-Balanced wiring system for the headphone outputs, giving the full benefit of balanced outputs when used with headphones and IEMs (fitted with balanced wiring) with low-noise and lower distortion. Even single-ended headphones benefit, as S-Balanced cuts crosstalk in half (without the need to re-wire headphones to benefit). And as always, we use the ultimate components…As is the AMR/iFi DNA, we love to audition and vet new parts as they come onto the market and where possible, use the ultimate components. Whereas some shun internals pictures, we always strive to show ‘what’s under the hood’ as customers like to make informed purchasing decisions based upon sonics and outright ‘sound for the pound’.The nano iDSD Black Label, while very affordable, is packed to the rafters with boutique components.  Specifications:Input(rear): USB2.0 type A “OTG” Socket (with iPurifier® technology built-in)Output(rear)； 1 x Audio fixed line out L+R 3.5mmDigital Filter: 2 positions, 2 filtersOutputs(front): 2 x Headphone Audio 3.5mm one direct and one with iFi iEMatch® integratedClock: Low-jitter crystal clock Filter–PCM: Listen(transient optimised minimum phase)Amplifier: Dual Mono 2 x 285mW Direct Drive, coupling capacitor free circuit for highest fidelityVolume Control: 3.5mm TRRS with Balanced compatible wiringChannel Separation: > 79dB @ 600Ω Load (Direct)Jitter(correlated): Below test set limitDimensions: 96(l) x 64(w) x 25.5(h)mmWeight: 139g (0.31 Ibs)Warranty period: 12months

Highest quality stereo analog audio up to 384kHz/32bit available on your PC, Mac, Linux computer, iPad or Android tablet. 2.0Vrms line output level, 112dB THD+N. Very low jitter oscillators, asynchronous 2.0 Audio Class USB. Also drives most medium- or high-impedance headphones. Highest value-for-money.Compact size (2x1.4x8.8cm) with hi-end performance hiFace DAC has been conceived to make hi-end equipment performance at hand to budget-conscious audiophiles, without any compromise. One hiFace DAC and a laptop, Mac Mini or even an iPad make for a hi-end music file source at the cost of a middle range digital interconnect.The hiFace DAC includes all necessary features to be the perfect DAC for all kind of hi-fi systems: asynchronous data transfer mode on USB 2.0, compliancy to USB 2.0 Audio Class (no drivers needed for MacOS, IOS, Linux and Android), very low phase noise oscillators and last-generation conversion IC capable of 384kHz and 23 bits.Windows users will enjoy it in Direct Sound, Kernel Streaming, WASAPI and ASIO (depending on the OS version), while Mac users will be able to take advantage from Integer mode and Direct mode. While the hiFace DAC output is purposely designed to give its best with amplifiers’ and preamplifiers’ line level inputs, it may also be used to drive medium- and high-impedance headphones: try it with iPhone’s in-ear headphones.Specifications:Connections: Input 1 x USB A type maleOutput 1 x 3.5mm stereo jack socket
