Revitalise studio recording sound with legendary K2HD
Despite their pristine clarity, digital recordings sometimes seem emotionally flat and lifeless.
Engineers at Victor Studio noticed a lack of emotion between their original masters and digital sub-masters, sparking a quest for a solution. They meticulously compared countless finished recordings with the copy recordings by ear, relying on their instinctive feel and human expertise. Their solution: K2 Technology.
The K2 Technology process revives rich, natural harmonics into digital sound, adding an organic quality unlike any other. K2 Technology processing revitalises the studio recording sound, infusing it with life once again.
“The K2 parameter values provided by iFi this time are completely new K2 parameter values that have never been used before and were selected by JVCKENWOOD and passed a listening test by studio engineers at Victor Studios. While previous K2 parameter values were set with consideration of correcting the sound quality of the product itself, the K2 parameter values provided this time for iFi are purely the settings for the best K2 effect. In this sense, it can be said that the K2 parameter values allow you to hear the original ideal “K2 sound.” commented, JVCKENWOOD. *Read Ifi's Tech Note for more information.
“K2 Technology” and “K2HD” are registered trademarks of JVCKENWOOD Corporation.
Advanced chip. Accurate clock.
The DAC section of the GO bar Kensei uses a powerful 16-core XMOS microcontroller to process the audio data received at the USB input. iFi's in-house team has programmed the XMOS firmware to optimise sound quality and ensure a perfect partnership with the 32-bit Cirrus Logic DAC chipset.
A customised digital filter minimises pre-echoes and ringing artefacts. iFi's GMT (Global Master Timing) precision clock system ensures ultra-low jitter.
Supports higher-than-streaming audio formats:
PCM up to 32-bit/384kHz
Native DSD playback up to DSD256
2x DXD
Full MQA decoding
Cut the Crosstalk
Connect to the GO bar Kensei via 3.5mm S-Balanced or 4.4mm Balanced headphone outputs.
iFi’s exclusive 3.5mm S-Balanced* technology cuts crosstalk and noise by 50% with regular single-ended headphones. *Read FAQ for more information.
K2HD
K2HD Processing revives rich, natural harmonics into emotionally flat and lifeless digital recordings.
The unparalleled originality of K2HD lies in its advanced high-frequency extension, enabling the restoration of natural harmonics and overtones beyond 22kHz, delivering audio quality that is close to the original master.
iFi worked with JVCKENWOOD for 18 months to develop this product and bring their renowned K2HD Technology back to the forefront.
XMOS 16-Core
The XMOS 16-Core chip processes the audio data received via the USB digital input.
This new low-latency XMOS microcontroller has greatly enhanced processing power. Compared to the current generation of eight-core chips, this new 16-core IC delivers double the clock speed (2000MIPS) and four times the memory (512KB), as well as the latest SuperSpeed USB standard.
iFi’s in-house digital development team has programmed the XMOS firmware to optimise sound quality and ensure a perfect partnership with the 32-bit Cirrus Logic DAC chipset used in the GO bar.
Global Master Timing
Extensive jitter-eradication technologies are applied to the digital stage, including iFi's GMT (Global Master Timing) femto-precision clock and intelligent memory buffer. This represents a total ‘out-of-the-box’ systematic digital solution that solves jitter once and for all.
Hi-Res True Native®
Hi-Res True Native® playback of all music formats from MP3 to DSD256, PCM384 and DXD384.
TDK
TDK C0G (Class 1 ceramic) capacitors offer high stability and low losses for resonant circuit applications.
Getting ever closer to the theoretical ideal of pure, frequency-constant capacitance, these capacitors reduce capacitor-induced distortion to vanishingly low levels.
They are pricey but are a perfect addition to Ifi products.
Panasonic OS-CON
Panasonic OS-CON caps totalling 5,410uF give very-low Equivalent Series Resistance (ESR), excellent noise reduction capability and frequency response characteristics. In addition, OS-CONs have a long life span and their ESR changes little even at low temperatures since the electrolyte is solid.
Tantalum Capacitors
Tantalum capacitors are another example of the top-notch components iFi prefer. These polarised electrolytic capacitors have superior frequency and stability characteristics, giving them a super high volumetric efficiency.
muRata
muRata control-type, low-ESR high-Q multi-layer capacitors. The ‘ESR control’ aspect of the Murata is something special. Their noise suppression abilities are impressive.
Analogue Circuitry
The GO bar’s analogue circuitry features a balanced design with a symmetrical twin-channel output stage.
This topology, usually reserved for larger and more expensive amplifiers owing to its cost and complexity, reduces noise and crosstalk in the signal path by fully separating the left and right channels.
