Description

iFi audio was launched in 2012 and its ultra high-end pedigree dates back a decade further through its parent company: Abbingdon Music Research (AMR) which produces expensive luxury audio products.

AMR saw in 2010 that hi-fi audio was shifting from home ‘static’ speaker systems to Bluetooth and portable ‘dynamic’ headphone setups To serve this growing market, iFi audio was commissioned with one goal: to produce ‘ultra-fidelity’ audio products that push the sonic performance at the envelope while still priced within the mainstream. It began work on a range of small but prodigious personal audio products using AMR’s trickle-down technology.

Today, iFi designs and manufactures over 35 different products from its headquarters in Southport, UK. It sources parts from around the world from manufacturers including XMOS (UK), GE Valves (USA), WIMA (Germany) and TDK (Japan). It retails through a global network of dealers and has its own distribution in the USA who serves retailers such as B&H and etailz.

S/PDIF. A SHORT HISTORY

Everything started in the second half of the 1980’s when the Sony/Philips Digital Interface (S/PDIF) entered the audio-visual scene. This new interface was designed to transport digital audio data from and to hi-fi components in a single-channel module, utilising encoding via a bi-phase-mark data stream. S/PDIF transmits data in frames, so that the elements of the bitstream could be better identified.

As one of the first interfaces transmitting a digital signal available for consumer and professional markets, S/PDIF enjoyed significant success. Fast-forward to today and S/PDIF remains a default connection type for sources such as Apple TV, Google Chromecast, PS4, Xbox or CD transport. Another reason behind this standard’s enduring popularity is a lack of an electrical connection between a transmitter and receiver, which prevents ground loops. However, establishment of a closer relationship with this interface, comes at a cost. Timing accuracy (or should we say inaccuracy) is what often detracts from the S/PDIF experience. Jitter as the parameter of timing inaccuracy is what impacts the data stream the most.

Jitter. What complications does it carry?

Jitter is the degradation of the audio signal when converting from analogue to digital and vice versa. Jitter is an audible deviation of the signal on the time spectrum, between the time when an event occurs and when it should take place. It affects data and clock signals, and if left unmitigated, it then manifests itself in a significantly lower audio quality. Jitter causes deficiencies in two audio domains; conversion and digital interference. When the audio conversion is exposed to this phenomenon, sampling jitter may induce errors, distortion and noise, whereas data corruption and loss of lock are a result of the digital interference. These obstacles turn an audiophile experience into an empty promise.

iFi audio. How do we solve the jitter issue?

After nearly four decades of research experience by our Chief Product developer Thorsten Loesch, iFi audio created an elegant and highly effective solution to eliminate jitter once and for all - the SPDIF iPurifier2. This petite accessory is here to stamp out S/PDIF jitter, fully restore the compromised signals integrity, rejuvenate sound quality, and create an increased warmth, depth and dynamic contrast.


10MHz Global Master Timing clock At the heart of SPDIF iPurifier2 lays 10MHz Global Master Timing clock, which allows for full signal reclocking. This superior Femto clock regenerates a stable, high-quality signal coming from a source device. Thanks to restored timing integrity the signal delivered to a receiver is not degraded by physical properties of a source product or a cable in-between. It also serves as an internal buffer to perfectly time the bitstream.	Galvanic Isolation The optical/Toslink input boasts the premium galvanic-isolation technology, where electrical circuits are separated to eliminate stray currents. Audio signals can pass between galvanically isolated circuits to block i.e. differences in ground potential or currents induced by AC power.	Tanatalum Capacitance Four large tantalum capacitors (100 uF) will reduce the EMI interference even further by improving the power supply signal. Due to their very thin and relatively high permittivity dielectric layer. These components gained significant recognition in audiophile circles. Tantalum capacitors also set themselves apart from their ordinary electrolytic counterparts by having high capacitance per volume (high volumetric efficiency).	Bit Perfect iFi audio SPDIF iPurifier2 employs Bit Perfect technology, hence it doesn’t involve over/upsampling of the signal. In other words, we appreciate the natural palette of sounds, which is why we purposely avoided digital processing. Both PCM and DSD signals are not altered in any way. In case of PCM stream, this approach is effectively called ‘non- oversampling’ or ‘zero-oversampling’, whereas for DSD it means that data retains its original format and is directly converted to analogue. The SPDIF iPurifier2 is compatible with MQA, DTS, Dolby Digital and DoP(DSD) signals and offers full HD

MCU firmware

The top-notch logical microcircuit designed by our programmers speeds up the processes of incoming data readout and monitoring the current data stream. In addition, the circuit generates a package of outgoing information through reclocking, regenerating and restoring the data stream., finally sending the outgoing stream in a consistent format.

Quieter than battery with the ultra-clean iPower 5V

iFi audio S/PDIF iPurifier2 demands the ultimate power supply. We can optionally upgrade your regular switch-mode wall-wart PSU to our own iPower 5V. It will feed your systems circuits with clean, audiophile-grade power and address issues at both the output and input stages. The iPower uses Active Noise Cancellation+ to cancel all incoming EMI/RFI noise. It is at least 10x quieter comparing to our previous power adapters, 20x quieter than audiophile linear power supplies and up to 1000x quieter than standard SMPS wall adapters.

Simply elegant design & sturdy built

SPDIF iPurifier2 is packed with the latest generation, audiophile- grade components, including two separate PCBs, each loaded with an advanced technology trickled-down from AMR’s multi- thousand-dollar DP-777SE DAC/preamp. This standalone, petite device plugs directly into either coaxial or Toslink inputs (via the supplied optical fly-lead and mini-Toslink adaptors) of the receiving device. Both sockets adhere to 75Ω for optimum connectivity.

The SPDIF iPurifier2 by taking out jitter, means your audio system will give you even more enjoyment out of the music. All very wallet-friendly.
