AAC (Advanced Audio Coding)

AAC is one of the most commonly-supported Bluetooth codecs in the wireless headphone and speaker markets. It’s also the default audio compression codec used by Apple’s iTunes and YouTube, and is supported across both iPhone and Android smartphones.

Active Noise Cancellation

Active Noise Cancellation (ANC) reduces unwanted sound by the addition of a second sound wave specifically designed to cancel out the first. This basically results in no sound at all as it reaches unwanted sound even at the lowest frequencies.

Passive noise cancellation is done by means of insulating filters and works best on the middle to high frequencies. It does not work on the lower frequencies meaning that some sound can still be heard.

Active 'v' Passive Speakers

So, what's the difference?

Active speakers have an in-built power amplifier and just need a power cable (or battery) to operate. Passive speakers require an external power amplifier to operate.

In short, you need an amplifier for passive speakers, you don't with active speakers.

Airplay

Apple AirPlay is found on all Apple devices. It lets you share videos, photos, music, and more from Apple devices to your Apple TV, favorite speakers, and some smart TVs.

Analogue 'v' Digital Signal Processing

Most modern systems use Digital Signal Processing. DSP samples analogue soundwaves into a limited set of numbers and records them. The overuse of DSP can result in an overcompressed unnatural sound and the translation and reassembly of data make digital devices prone to loss of quality.

All iFi products use Analogue Signal Processing as we believe it is better suited to audio. ASP does not cause signal quality to be lost as it records waveforms as they are and produces a more natural sound. 

Analogue 'v' Digital Volume Control

For cost and convenience, modern DAC chips have a built-in digital volume control. The drawback is that a digital volume control works by 'truncating' the signal. Or 'chopping Bits' of resolution. For a 16-Bit music file at 50% volume level means the listener is actually listening to 14.5-Bits!

All iFi products bypass the digital volume control and use a separate analogue volume control which does not 'lose Bits' so a 16-Bit file stays unchanged which delivers maximum resolution.

Losing Bits of resolution (quality) is like having missing pixels on a computer or TV screen.

Apple CCK and Android OTG

So, why don't we provide these two cables with our products?

The Apple CCK cable can only be purchased from Apple. We can't make one ourselves as it has a special chip in the cable that we'd need to use for them to actually work with Apple hardware. Sadly, Apple has not released this chip to anyone. 

We can and do make two versions of an Android OTG cable - Type C and micro.

aptX

aptX Bluetooth transmission is found in most Android phones, media players, Apple computers (macOS on iMacs and MacBooks) and on higher-quality Bluetooth headphones. It is not available on iOS (iPhones and iPads use Advanced Audio Codec).

aptX LL

aptX™ Low Latency audio ensures your Bluetooth® wireless enabled device can deliver sound in sync with visual media. It reduces delay and improves end-to-end speed of the audio transmission, resulting in a high-quality, synchronised user experience.

With aptX™ Low Latency you can enjoy the freedom of wireless for applications such as gaming and watching videos.

Balanced audio

This is a type of audio circuitry topology that uses individual left & right channels.

It is a superior method to the single-ended circuit approach. Balanced circuits reduce noise and crosstalk.

While single-ended is used by most at this price level, iFi is implementing balanced circuits across the Zen range which is quite a step-up.

Balanced 'v' Unbalanced

Let's talk headphone cables.

An unbalanced headphone cable has a left + and right + wire, for each respective side. The other, the third - wire is shared by both left & right channels. As this is shared, this gives rise to undesired coupling noise which is commonly referred to as 'crosstalk.'

A balanced cable has the same left + and right +. But it has a separate left - and right -. With totally separate wiring 'crosstalk' is negligible.

Therefore, a balanced connection is the superior headphone wiring configuration.

Bit-Perfect

If a file is "Bit Perfect' it means it has stayed the same. For example, if a PCM file is played through a DAC to improve the sound quality and the DAC does not change the file format. The file is 'Bit Perfect'.

Bluetooth 5.0®

This is the latest version of the Bluetooth wireless commnunication standard.

Its main benefits are improved speed and greater range - it's faster and can operate over greater distances than older versions of Bluetooth. You can find out more here.

Busbar

A busbar is simply a conductor through which current flows.

CD Transport

A CD transport concentrates on reading the information held on a compact disc without expending effort in turning that digital signal into an analogue output, unlike a CD player. All you need to do is add an external DAC.

Class D Amplifier

A class-D amplifier or switching amplifier is an electronic amplifier in which the amplifying devices operate as electronic switches, and not as linear gain devices as in other amplifiers. Just like SMPS (Switch Mode Power Supplies), standard Class D amplifiers have an inherent noise issue due to their 'switching' nature.

Common Noise Filter

The common noise filter cuts out most noise gremlins found in typical audio systems such as RFI/EMI.

DAC (Digital-to-Analogue Converter)

DACs convert digital information, stored or streamed by computers, into music we can hear through speakers or headphones.

Every device that's a source of digital sound has a built-in DAC (TVs, games consoles, CD players, phones, portable music players etc). Dedicated external DACs sound much better than standard DACs used in digital devices such as phones.

DAP (Digital Audio Player)

A DAP is a device like an iPod or an MP3 player that stores and/or plays back music digitally.

DAW (Digital Audio Workstation)

A digital audio workstation (DAW) is an electronic device or application used for recording, editing and producing audio files. It's basically a mixing desk.

DC Offset

DC offset is a naturally occurring phenomenon of the electrical system. It is a potential source of clicks, distortion and loss of audio volume.

DSD (Direct Stream Digital)

DSD is a very high-quality digital audio format that's even better than CD quality. The higher the 'DSD rate' – DSD64, 128, 256, 512 and 1024 - the greater the amount of music information available, which means better sound quality.

Files can be remastered to higher file rates to improve sound quality. The pinnacle of this is DSD1024. Not many machines out there are capable of this feat.

DSP (Digital Signal Processing)

Digital signal processing (DSP) is the use of digital processing, such as by computers or more specialized digital signal processors, to perform a wide variety of signal processing operations. When it comes to audio the overuse of DSP can result in an over-compressed, unnatural sound.

EMI (Electromagnetic Interference)

EMI is a type of interference caused by errant and unwanted electromagnetic waves that are received and amplified by an audio system. They cause some of the annoying 'audio gremlins' we often talk about.

F.A.S.T (Full range And Super Tweeter)

This is basically a super tweeter. A speaker driver intended to produce ultra-high frequencies in a multi-driver loudspeaker system. They are used to supplement the sound of tweeters by reproducing frequencies which the tweeter may produce only with a narrow polar output, or perhaps with distortion.

File formats

MP3 – this is the most popular format, every device in the world can use it.

DSDDirect Stream Digital is a very high-quality audio format, better than CD quality. The higher the number (sample rate), the better the recording - DSD64, 128, 256, 512 and 1024.

PCMPulse Code Modulation is the most common format for CDs and DVDs.

DXDDigital eXtreme Definition is a very high-quality PCM format. It was developed to edit hi-res (high quality) recordings recorded in DSD.

Filters

Filters are used in music to alter the harmonic content of a signal, which changes its timbre or sound.

Just as using a coloured filter on a camera lens will alter the look of the resulting photograph to set the right mood, filters work in a similar way in audio.

Gain

Gain is the amount of increase in audio signal strength. Gain is often expressed in decibels (dB).

Galvanic Isolation

Galvanic isolation is a design technique that separates electrical circuits to eliminate stray currents that contain noise. Signals can pass between galvanically isolated circuits, but stray currents, such as differences in ground potential or currents induced by AC power, do not pass. This means little or no noise interference to the audio signal from stray currents.

Ground Loops

In an electrical system, a Ground or Earth loop occurs when two points of an audio system both have a ground reference which causes a 'potential voltage difference' between them. Ground loops are a major cause of the noise, hum, and interference in audio, video, and computer systems.

HWA

HWA is Bluetooth® wireless audio powered by LHDC™ and used by Huawei.

LHDC™ is codec developed by Savitech and stands for 'low latency and high definition' audio. Compared to standard Bluetooth®, it allows 3 times more musical date to be transmitted.

IEMs

IEMs stands for In-Ear Monitors.

These fit inside your ear. You've been using them for years. You just called them something else.

You will also see these referred to as earphones, ear buds and CIEMs. CIEMs are Custom In-Ear Monitors - IEMs made specifically to fit your ear shape.

LDAC

LDAC is an audio coding technology developed by Sony, which allows streaming audio over Bluetooth connections up to 990 kbit/s at 24 bit/96 kHz (also called high-resolution audio).

It is used in Sony headphones, smartphones, portable media players, active speakers and home theaters.

LDAC is a lossy codec which means is disgards some of musical info to make the file smaller.

Lossy v Lossless

Lossless and lossy compression are terms that describe whether or not, in the compression of a file, all original data can be recovered when the file is uncompressed.

With lossless compression, every single bit of data that was originally in the file remains after the file is uncompressed.

On the other hand, lossy compression reduces a file by permanently eliminating certain information. Lossy audio files do not retain the natural authenticity of the original.

MQA (Master Quality Authenticated)

MQA is an award-winning British technology that delivers the sound of the original master recording. The master MQA file is fully authenticated and is small enough to stream or download. More here.

NAS (Network Attached Storage)

Network-attached storage (NAS) is dedicated file storage that enables multiple users and client devices to retrieve data from centralized disk capacity.

Users on a local area network (LAN) access the shared storage via a standard Ethernet connection. NAS devices typically do not have a keyboard or display and are configured and managed with an app.

Native playback

Native playback simply means that the file format has not been changed.

You wanted to listen in PCM, you'll still be listening in PCM. The DAC does not change the format of the original file.

Noisebusters!

Reference to the 1984 film Ghostbusters. Four guys, a girl and ghosts. And proton guns that would destroy the world if you crossed the streams. Watch this.

Omotesando

Omotesandō is known as one of the foremost 'architectural showcase' streets in the world, featuring a multitude of fashion flagship stores within a short distance of each other.

These include the Louis Vuitton store (Jun Aoki, 2002), Tod's (Toyo Ito, 2004), Dior (SANAA, 2004), Omotesandō Hills (Tadao Ando, 2005) and Gyre (MVRDV, 2007), amongst others. More here.

Polarity

In simple terms, polarity refers to the way a signal flows.

Audio signals generally flow one way, like DC current, and have positive polarity. Inverting the polarity can have a negative impact on sound and equipment.

Pulse Load

A 'load' refers to a current drain that is applied to a battery. For example, charging the flash in a camera. The term 'Pulse Load' indicates that the load is automatically applied for a specific period of time, then disconnected without user intervention.

RFI (Radio-frequency interference)

Radio-frequency interference (RFI) is very similar to electromagnetic interference (EMI) but is found in the radio frequency spectrum. It is another source of irritatiing, unwanted noise often talked about as an 'audio gremlin'.

Top tip: just don't add water.

Shigeru Ban

Shigeru Ban (坂 茂 Ban Shigeru, born 5 August 1957) is a Japanese architect, known for his innovative work with paper, particularly recycled cardboard tubes used to quickly and efficiently house disaster victims.

He was profiled by Time magazine in their projection of 21st-century innovators in the field of architecture and design. Find out more here.

Solid-state 'v' Tubes

A solid-state amplifier uses electronics such as diodes and transistors to amplify the music signal. A tube amp uses valves/vacuum tubes to do the same job.

There is a noticeable sound difference between the two methods. Some feel that tube amps create a warmer, more musical tone. Some companies choose to build 'hybrid' models that combine the two methods.

Soundstage

So, what is soundstage?

Imagine yourself in a small theater, 10 rows from the front, dead center, watching an orchestra perform on stage. Now close your eyes. This is the 'sound stage'.

In audio speak, it is an imaginary 3D space created by the high-quality reproduction of sound in a stereo speaker system. In other words, the soundstage allows the listener to hear the placement of the orchestra vis-a-vis instruments when listening to a given piece of music.

Spotify Premium

Spotify Premium allows you to listen better quality music. It's all about bitrates. The bitrate is the amount of data processed over a certain amount of time. The higher the bitrate, the better the quality.

On normal Spotify you listen at 96kbps, the 'standard' bitrate on mobile or at 160kbps, 'standard quality' on desktop and 'high quality' on mobile.

With Spotify Premium, you get 320kbps which is 'high quality' on desktop and 'extreme quality' on mobile. Basically, more bitrates for your buck.

Tadao Ando

Tadao Ando (安藤 忠雄 Andō Tadao, born 13 September 1941) is a Japanese self-taught architect whose approach to architecture and landscape was categorized by architectural historian Francesco Dal Co as "critical regionalism".

Tidal Masters

Tidal is a subscription-based audio streaming platform, similar to Apple Music and Spotify, but with lossless-quality audio. Tidal Masters is the section with the highest-fidelity music streamed including some files in partnership with MQA.

Lossless-quality means that no music quality is lost in this format.

USB Audio

USB audio is a digital audio connection used to send digital music from your computer to a digital to analogue converter (DAC). Usually computer manufacturers spend most of the overall budget on the processors and screen, leaving minimal budget for the built-in DAC and audio outputs.

Volumetric Efficiency

In electronics, volumetric efficiency quantifies the performance of some electronic function per unit volume, usually in as small a space as possible.

ZEN

Zen emphasizes rigorous self-control, meditation-practice, insight into the nature of things and the personal expression of this insight in daily life, especially for the benefit of others. Discover more here.

Mood music

Finally, we’ve given you a choice of headphone sockets and outputs to cover all tastes. Big ones, little ones, balanced ones…

The Pro iDSD now currently comes in two ‘balanced’ versions – with 4.4mm or 2.5mm balanced headphone sockets. You choose which version you need.

So, whatever your mood, however you connect or listen, the Pro iDSD has an option for you.

The Pro iDSD has a 'quad 'stack' of Bit-Perfect DSD and DXD DACs by Burr-Brown. The 'interleaved' configuration means up to 8 pairs of differential signals can be used and mixed, equal to 4 pairs of signals per channel.

Full lowdown? User Manual, page 13.


The Pro iDSD employs the new XMOS XU216 X-Core 200 Series 16-Core processor. All-digital processing is Bit-Perfect unless particular digital filters are explicitly selected.

Explore the XMOS here.


Upsampling to DSD1024 has previously only been available to a select few. The Pro iDSD makes it available to a wider audience. The DSD1024 remastering is handled by the Crysopeia® FPGA and this is where we believe the FPGA excels.

Discover more on page 15 of the User Manual.

Listen to Master Quality Authenticated audio straight out of the box. Connect to Tidal Masters and check the option to stream MQA.

Our video tutorials on You Tube show you how.


Data is sent to the Memory Buffer from all inputs. Here it is de-jittered to eliminate any transmission of source jitter to the DAC output. The data from the Memory Buffer is further re-clocked by the low-jitter Global Master Timing® clock, which also drives the X-Core 200 and FPGA. 


With LINKPLAY™ WiFi/network playback, built-in Spotify and Tidal, and wide protocol support for 32-Bit/192kHz and DSD64, the Pro iDSD can be also used without a computer to stream audio directly.


Galvanic isolation is the ‘holy grail’ of computer audio.

All inputs are galvanically-isolated (including USB). The USB input section has its own separate power management system with multiple regulators and filtering operating from the galvanically-isolated voltage generated to power this section.


Unlike other amplifiers that have the same circuit and just switch in/out the tube section, the Pro iDSD is the very first of its kind to have two individual input circuits - one tube (General Electric 5670 tubes!) and one solid-state. This results in the 'best sonics of both worlds'.

Read more. Page 7.


We've given the Pro iDSD an extra Tube+ setting. This reduces overall loop-gain and negative feedback to the minimum and presents a different sonic perspective between the tube’s natural harmonics and transient performance.

Sound it out in the User Manual, page 7.


The amplifier audio circuit is fully discrete, fully-balanced with either tube or J-FET input switchable, bipolar second stage and MOSFET-buffered bipolar Class A Power stage.


The Pro iDSD is packed full of premium components - a Japan Alps rotary volume potentiometer, audio-grade ELNA Silmic capacitors and a bank of Elna Dynacaps ‘super capacitors’.

Reviews

Best DAC and headphone Amp in this price range.

Received this DAC yesterday and pleased with the sound on my Sennheiser HD800s using gain of 18. These are power hungry headphone and had zero issues with this DAC. Everything from Jazz, blues, rock and rap were great.

You really need to use a balanced connector. This model uses a 2.5mm connector for balanced.

Ordered a Silver Dragon via balanced 2.5mm connector from moon-audio. Cable arrived and I’m now simply blown away with the difference.

Highly recommend when you receive this DAC you download the USB Windows 10 driver and the latest firmware. The unit supports MQA, but needs the firmware to work.

Streaming to wireless is ok. You won’t receive the same quality. Use a computer and USB 3.

I stream via Tidal and Spotify. If you want to support MQA with this device and windows 10, make sure in Tidal you tell it under settings not to use software compression of MQA and do a pass through.

For hifi, I run all Martin Logan electrostatics in dolby atmos in my media room. Preamp has 3d for atmos music. With my setup running three amps and about 4000 watts of prestine class A amps. Not bragging here, but it sounds freaking amazing for movies and music. What I’m getting at is with this media room setup, Im now relaxing in our master bedroom using my headset and this DAC.

Will this also power planar headsets? The answer is simply yes. Also have Audeze LCD-X with Black Dragon cable. No issues.

If you are looking at a separate DAC and amp, don’t. This is powerful enough.

Just buy it. It has been comparable to 14k DACs from hifi reviews.

Yes, it’s just this good

REVIEW: IFI AUDIO PRO IDSD

“This sound signature is mirrored through the headphone output, with a wide soundstage, excellent layering and natural yet tightly balanced sound.”

“Turning on Tube mode does what you would expect, and I really love this option. It adds a little bit of warmth and body without taking away detail.”

“As with most iFi Gear, the Pro iDSD just gets the job done, and does it very well. It is a neutral and detailed DAC with excellent soundstaging, layering and resolution. Turn on tube mode and you get a little hint of tube magic without masking the finer detail. The Pro iDSD is versatile and flexible, allowing you to stream and play files from a harddrive/SD card along with accepting most of the current digital inputs.”

The Ultimate All in One Device for Music Listening

I bought this for several reasons. I wanted a DAC and Headphone Amp for my desk. I also wanted a Tube and Solid State Headphone Amp. This also allows for network connection for several uses. It has balanced and unbalanced (single ended) connections for headphones, and a plethora of inputs/outputs.

What I got is a stunningly beautiful unit that plays music just as well as it looks. This checked all my requirements and I got a whole lot more. With some formats of music, I can get 45 permutations of how I want the music played. I can use this for solid state, tube or both combined. It has a variety of filter methods, and plays all of my files just fine. I can connect a CD player and bypass the built in CD DAC and sounds fantastic.

The other benefits, it supports upsampling, DSD and DXD, MQA (For Tidal Streaming and offline.)

Speaking of Streaming, this can be run independently with no other sources, other than network and stream Tidal or play right out of the microSD or USB connections via USB key or disk. I can also connect my iPhone through AirPlay or just connect it to the USB 3 port using the Apple CCK cable.

Did I say the sound is incredible? Makes my DSD songs come alive, and even regular CD quality audio sounds nicer and clearer.

I have been listening to music for decades, and this unit allows me to enjoy music again, old or new.

Hands down, one of the best investment in audio gear for playing music. If you’re purely focused on listening to MP3 and AAC, this may not be for you. But if you’re listening to CD quality and better (HiRes, DSD, MQA), then this unit is a must in any home or work environment.

Make sure you pair this with a nice pair of headphones as that is critical to hear the difference. I usually pair this with Planar or very large dynamic driver based headphones.

An added touch and coolness factor, take a look at the iFi Pro iRack to set this on. Makes it look even better.

Hope this helps.

iFi Audio Pro iDSD

“I kick off with a 24/192 FLAC recording of Beethoven’s Piano Concerto No.5 – The Emperor by the Scottish Chamber Orchestra. The clarity of the piece is outstanding and the orchestra is superbly balanced with excellent spatial imaging. The top end is very clear and open, and the piano has a very real presence in the soundstage, even though I am listening on headphones.”

“With the output mode set to Solid-State, it produces an extremely clear and bright sound through the Sennheiser headphones, while selecting Tube rounds off the corners of this very bright rendition and produces a sound that is far more realistic and refined, without any loss of clarity or openness”

“The Pro iDSD is a phenomenally flexible component that delivers authoritative performances.”
