Device port is the Dac.
In computer terminology host port is the controller and device is ‘pheripheral’.

iFi audio has recently returned from a couple of outstanding audio shows – CanJam in New York City and Bristol Sound and Vision in the UK.

As promised, audiences had the chance to audition the pre-production model of the new Pro iDSD. This gave us the invaluable opportunity to gather feedback from the end user, directly.

We couldn’t miss out on the final chance to let our potential customers drive the Pro concept forward just one more time.

So, as is our want, we have taken the feedback on board and are tweaking the hardware and the software in response to these comments.

It seems that certain markets required the additional 2.5mm headphone socket and some the 4.4mm – so we’re doing both. Watch this space for more info on how and why!

Inevitably this will have an impact on the official launch date of both the Pro iDSD and the Pro iRack which we intend to launch together.

Skin says he needs until the end of May to implement these tweaks and will be able to give us a definite launch date nearer the time.

Can you guys at least make the Pro iDSD user manual available on the iFi website?!! I, for one, would appreciate the opportunity to go throuh the manual prior to the actual release of the product. Thanks for your consideration.

I like that idea. I have one. I will ask if I may distribute it if the website is not updated.

Will purchasers have the option to purchase either version, depending on their individual needs/preferences? Or, will you limit distribution to only one version per market?

Finally, speaking for the entire iFI enthusiast community, can you PLEASE release the version with the 2.5mm socket on 3/15/18 as most recently promised?!! You must have a supply of these units ready as their release was FINALLY supposed to take place this week.

I am not positive if folks in the U.S. will have access to the 4.4mm version yet. I have asked the question.

Speaking for me too

Due to the 4.4mm version being put into the mix the team has decided to continue work on the firmware to make it bulletproof. A lot more testing protocols have been added to ensure the release is smooooooth.

iFi Audio Pro iDSD
The official Launch release

Having sparked a revolution with its low-cost DACs that offered music fans portable 256 stereo for less than £500 a few years ago, iFi has maintained its position at the vanguard of the audio world with the launch of the ground-breaking Pro iDSD. There is simply nothing like it.

We have paid great attention to every section of this DAC/headphone-amp/preamp – no stone has been left unturned. Tried and tested classic noise reduction techniques found in tube equipment have been combined with cutting-edge, 21st century technology to deliver a superlative performance.

The quad section uses a quad “stack” of Bit-Perfect DSD and DXD DACs by Burr-Brown in a custom “interleaved” configuration. This arrangement enables a total of eight pairs of differential signals to be used and mixed totalling four pairs of signals per channel.

In a nutshell

The iFi Pro iDSD is a revolutionary DAC that combines a number of different features to give your home audio system the best possible playback resolution and sound. It can handle all audio formats to DSD1024 or DSD512 or PCM 768K with user-selectable digital filters.

Wireless Playback

With LINKPLAY™ WiFi/network playback, built-in Spotify and Tidal, and wide protocol support for 32-Bit/192kHz and DSD64, the Pro iDSD can directly link to a router for online music play. This gives it the option to:

• Play direct from SD card
• Link to a router and directly stream (TIDAL/MQA, Spotify etc)
• Use DLNA (Digital Living Network Alliance) via music stored on HDD

It’s taken a while to come to market but, boy, has it been worth it. This innovative digital engine will shape the next generation of iFi products and they will rock the digital world.

The gang of four

A quad “stack” of Bit-Perfect DSD and DXD DACs by Burr-Brown work in a custom “interleaved” configuration so that up to eight pairs of differential signals can be used and mixed.

Digital Processing

The new XMOS XU216 X-Core 200 Series 16-Core processor has a maximum of 2,000 MIPS (two billion instructions per second) calculation power in dual-issue mode as a USB interface.

Crysopeia FPGA Digital Engine

The FPGA excels, by handling the up-sampling duties to attain the DSD1024 audio format. In fact, the Pro iDSD can handle all audio formats to DSD1024 or DSD512 or PCM 768K with user-selectable digital filters.

Wireless playback

With LINKPLAY™ WiFi/network playback, built-in Spotify and Tidal, and wide protocol support for 32-Bit/192kHz and DSD64, the Pro iDSD can directly link to a router for online music play.

One customer wrote "I had major issues when I had an iDSD BL a while ago, with volume control driving my MrSpeakers AEON Closed. I couldn't use past 9 o'clock on the volume knob using 'Normal'. And the high and ultra IEMatch settings restricted dynamics way too much and I wasn't able to enjoy these settings."

We offered the following as a reply:

'Normal' is equal to 12dB gain. So it is more gain to the HP than iDSD Pro in the middle (9dB) position. 'Normal' on the iDSD micro in effect matched the original iCAN micro in the lower gain setting.

In 'Eco' mode headphone gain is 0dB so this should be used if there is not enough adjustment range for the volume control. This is also stated in the manual.

For iDSD Pro, we selected slightly lower gain levels, as the balanced output is 6dB 'hotter', so going for 0/9/18dB kind of breaks the difference in half, for balanced the effective gains are 6/15/24dB.

Hello, looks amazing! Are the drivers stable with the current macOS? Also, has this been tested in a professional audio situation with DAWs? I am wondering if this would be a stable option as a mastering DAC in conjunction with other interfaces. I see it can receive clock etc. Thanks!

iFi audio - The GTO filter
Part 1/4 - The TL;DR

What iFi GTOTM is?

Based on AMR’s ‘Organic’ mode, the further refined iFi GTOTM Digital Filter resolves a number of audible problems associated with both classic digital filters AND non-oversampling systems, sounds on par (or better in optimal systems) to the latter and its transient optimised performance is similar.

How iFi GTOTM does it?

Our GTOTM filter tuned to fit inside the ‘ringing envelope’ of our own hearing makes ultrasonic ringing objectively measurable yet not perceived. It essentially ‘masks’ this time-domain distortion to make it inaudible.

Why do I want iFi GTOTM?

Because it provides natural sound free from audible time domain distortion!

I would love to learn more about the Gibbs Transient Optimised filter. I have the Pro iDSD on loan now (thanks, Tyler) and the GTO filter is my favorite so far.....even though I have NO idea what it does or how it does it. It sounds relaxed/natural, however. Kudos to the engineer behind this one!

We'll be gradually releasing tech behind our GTO very shortly. Stay strong, we'll deliver.
