It is a superior method to the traditional single-ended circuit approach. Balanced circuits reduce noise and crosstalk. Less Interference – clearer sound.

You normally find this set-up in products at the higher end of the price spectrum such as the Pro iCAN Signature but iFi is now using this across its range to produce the best quality audio for all our customers.

Balanced, differential analogue circuit design has long been championed for its ability to reduce noise and cross-talk within the signal path by fully separating the left and right channels.

PureWave is a new, balanced, symmetrical dual-mono topology with short, direct signal paths. The name refers to the sonic purity it achieves thanks to exceptional linearity and infinitesimally low levels of noise and distortion.

The iFi exclusive S-Balanced technology made its debut in the original Pro iCAN. Since then, it has become a significant feature in across the iFi range and features as an integral part of the xDSD Gryphon.

It delivers the maximum performance from both single-ended and balanced headphones. The S-Balanced (single-ended compatible balanced) 3.5mm headphone output delivers the benefits of the balanced connection to single-ended headphones.

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. The xDSD Gryphon adopts MQA technology to receive and decode MQA audio and provide master-level sound.

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.

The OLED in the xDSD Gryphon sports a SilentLine design. This ensures that there is no electrical noise to interfere with the audio signal.

The way its switches between settings has been engineered to ensure sonic transparency – FET-based switching is handled by a microcontroller, which only ‘wakes up’ when the user changes a setting, thus eradicating any sonically deleterious interference.

We use Qualcomm’s new QCC5100 Bluetooth processing IC in combination with proprietary circuits to create an audibly superior ‘Bluetooth engine’.

All the current high-definition Bluetooth audio formats are supported – Qualcomm’s aptX Adaptive and aptX HD, Sony’s LDAC^TM and HWA’s LHDC, regular aptX and aptX Low Latency, AAC (Apple iOS devices) and SBC (the ‘plain vanilla’ Bluetooth codec).

Among the 24-bit-capable codecs, aptX HD supports up to 48kHz, whereas aptX Adaptive, LDAC^TM, and LHDC can reach 96kHz.

iFi’s ‘Bluetooth engine’ can also be updated over-the-air, so future codecs may be added.

Negative feedback’ is used in amplifier circuits to compare the output signal with the input signal and correct errors, in order to control gain and reduce distortion.

For sound quality, this is positive; BUT commonly applied, one-size-fits-all ‘global negative feedback’ can also highlight different problems at the same time as solving others – corruption of the error signal, phase shifts, group delay and so on can all have a negative impact on sound quality.

We recognised that different parts of a circuit benefit from specifically optimised feedback loops and have developed a negative feedback system that is much more accurate than the usual approach. This incorporates multiple feedback paths instead of a global loop, each path optimised for a particular function and working synergistically with the others to deliver optimal overall performance.
