REFERENCE

The new REFERENCE presents Unheard Realism moves yet again the threshold of what is achievable in absolute speed, authority and clarity. With REFERENCE, the signal transmission takes another giant leap closer to absolute preservation of the source signal. Both bandwidth and timing accuracy ensure perfect integrity of the information. The word ‘reference’ stems from Latin where it means relation, carrying and bringing back. The interconnect cables are developed and built from the ground up to bring back the original recorded musical event in its purest and truest form.

Technical specifications:

Further optimised and upgraded silver conductors that bring inductance and capacitance even further down, cotton damped air dielectric insulation with completely separate conductors. The improved geometry provides perfect phase behaviour with the lowest possible time domain smear.

KALI

In pursuit of absolute signal preservation, Kali interconnects almost double the conductor spacing of our Reference line while maintaining perfect transmission-line characteristics. This extreme geometry provides unlimited dynamic headroom and unmatched signal transmission speeds enabling even the fastest transients to pass without constraint.

Time is the dimension that hi-fi so often sacrifices in pursuit of other qualities. Kali interconnects refuse all compromise. Pure silver conductors eliminate copper's microscopic non-linearities and precisely calculated lengths optimise the cable's resonant behaviour as a transmission line. The result is a cable that neither enhances nor beautifies, only allows the signal to remain completely itself, more so than any other conductor can achieve.

Phase distortion drops to unprecedented levels. The noise floor vanishes and what emerges is not a "sound" but the absence of interference, your source components speaking directly to your amplification with nothing between. The Kali interconnect is not about what it adds to music but about the beauty it reveals by leaving the signal untouched.

When the question is about ultimate transparency - Kali is the answer.

Technical specifications:

High purity unstressed silver conductors in optimised transmission-line geometry.

Significantly increased conductor spacing versus Reference line.

Specific lengths calculated for minimal resonant interference.

Highest grade CNC machined silver terminations.

KALI

When cost ceases to be a consideration, when material constraints are lifted, and when nearly two decades of cable research reaches its ultimate expression, you get Kali. Named after the Hindu goddess of time, our flagship speaker cable embodies the fundamental force that governs all audio reproduction. Kali offers no compromise and no compensation. It simply reveals what exists in your system with a transparency and dynamic freedom that redefines the possible.

And frankly, when a cable is this transparent, when it leaves absolutely no fingerprint whatsoever, we needed a name that would give it a little character.

In Sanskrit tradition, Kali is both destroyer and liberator—the force that removes illusion to reveal truth. The Kali speaker cable destroys the barriers between source and speaker, liberating your system's true potential. Where other cables impose character due to their limitations, Kali neither imposes nor retracts anything. Pure silver conductors and transmission-line optimised geometry and length, executed with 50% wider conductor spacing and bandwidth than our Reference line, creates unlimited headroom and impeccable time coherence across the entire frequency spectrum. This is not a subtle refinement, but a complete transformation of what came before.

Kali achieves what seemed impossible: improving upon cables that already had no 'sound'. Alan Sircom put it most succinctly: "If it were possible to directly couple the output of one device with the input of the next, that would be Kali". Micro-transients and macro-dynamics are handled with identical precision. The honest truth of your equipment emerges - mesmerising, beautiful, raw. Untouched as nature, with all it's perfect imperfections laid bare.

This is Kali: time domain perfection, unrestrained.

Technical specification:

High purity unstressed silver conductors throughout.

Transmission-line optimised lengths for minimal resonant interference.

Ultra-wide geometry maintaining perfect phase coherence and perfect micro and macro dynamics across unprecedented bandwidth.

Custom pure silver terminations engineered for the lowest possible signal losses.

KALI

Power is not constant. Music demands immediate current delivery. Both amplifiers and sources require instant current from the mains. This causes local voltage modulations that are also known as mains noise as they travel back into the mains. The capacity and speed at which these voltage modulations are channeled away enable the required voltage recovery, and thereby define transient impact and temporal accuracy. The Kali power cable obliterates this physical constraint using the same transmission-line principles we apply to our signal cables and speakers. Pure silver conductors, 50% wider than our Reference line, create a power delivery system with such massive headroom that both the most explosive musical moments and the most delicate signals are delivered unrestricted with startling clarity and the finest nuance.

The goddess Kali represents both creation and destruction, a dynamic force of transformation. The Kali power cable channels this energy, delivering power with a speed, delicacy and authority that unlocks a system's true musical potential. Where conventional power cables constrict and colour, Kali simply disappears, allowing the music unrestricted freedom. The low-frequency authority, the micro-texture, the macro-dynamic slam, the sense that your system has limitless reserves - this is what unrestricted power delivery sounds like.

Kali is not about "cleaning" power or "filtering" noise. Kali simply provides fundamentally correct, unrestricted and frictionless transmission-line behaviour such that power seems instant and in perfect time-domain alignment. The result is not a character but a capability allowing your system to operate beyond what its designers could imagine.

Quality power is undoubtedly the most critical premise for your system's ability to live up to its true potential. Kali liberates your system like nothing else.

OePhi Integrated Amplifiers (stereo or mono)

Electronics

One of the most neutral and transparent amplifiers available thanks to its short and pure signal path and best available components. OePhi amplifiers are based on the class AB principle with low bias current. This means that only one bipolar output device will drive the waveform. Together with elaborate use of current-mirrors in the input, VAS and driver stages, the amplifier has an ability to unpack the music with dynamic contrast, absolute clarity and neutrality that gives it it’s uniquely natural ‘sound’ -or rather unique lack of ‘sound‘.

Combined with resistor-ladder volume control and direct signal path, internal OePhi cables throughout both power supply and signal paths, OePhi’s amplifiers offer a unique no-compromise performance housed in a discrete design with real oak front panel and aluminum chassis.
