Each Kii THREE contains six channels of DSP, D/A conversion and power amplification. Few companies could pull off such a densely packed design with truly world class performance electronics. But then again, few active speakers are designed by people who have previously turned high end power amplification and digital conversion around.
Each Kii THREE holds 6x250W power amplifier boards, designed by Bruno Putzeys using the latest iteration of the Ncore class D technology which he invented for Hypex. Unique to the implementation used in the Kii THREE is a combined voltage/current control loop that goes beyond merely a better amp – it actively improves the distortion performance of the drive units which contributes significantly to the extreme resolution of the speaker.
Naturally, this means that the performance of the AD/DA conversion has to match that of the amps. This task fell to Bart van der Laan who has a long track record designing DSP and converter boards for high-end professional audio equipment. Kii Audio’s implementation is a runaway success: a complete pass through the AD/DA circuitry of the THREE’s signal processing board is entirely inaudible, a feat not duplicated by the most expensive audiophile standalone units.
Alongside the Active Wave Focusing filters the DSP is responsible for keeping the drive units within their safe operating range by gently adapting the filters instead of brutally limiting the signal, allowing the THREE to play significantly louder and cleaner than much bigger traditional designs.
On the input side there is a choice of analogue, digital inputs. All digital inputs are up-sampled and reclocked using Kii’s own jitter rejection algorithm that guarantees actual “bits is bits” audio performance for any digital source.
The electronics package alone sets a milestone. What it does in concert with the unique acoustic design defies imagination. You have to hear it to realise the magnitude of the revolution the Kii THREE represents.
The Kii CONTROL turns the Kii THREE into a complete playback system of highest sonic quality and usability. It offers a user interface for your speakers and works like a digital preamplifier.
Only connect your analog source, CD player/drive, server, streamer, TV set or set top box to enjoy a breathtakingly audiophile full range system in a stunningly small footprint.
The Kii CONTROL offers three additional digital inputs for the Kii THREE:Coax SPDIF, Optical TOSLINK and USB (up to PCM 24/384kHz and DSD64/DSD128 on USB).
All inputs are located on the backside connector panel and can be activated with the touch buttons located around the volume knob. A dedicated input button (labeled XLR) will switch to the existing hardware input on the speaker itself, which you can continue to use as analog or digital input. The Kii Control connects with a single included CAT6 cable and is also powered through this connection. No additional power supply is necessary.Most importantly the Kii CONTROL enables lossless volume control inside the DSP of the Kii THREEs, keeping the signal path of the system as transparent as possible.
The big volume knob also offers mute or dim functions and manual power on/off (standby). A dedicated touch button provides direct access to up to six user definable presets.
The menu navigation and OLED display vastly expand the options of the Boundary and Contoursettings, while also providing access to more advanced system settings, including amongst others for example manual power on/standby, LED brightness, DIM function and limiter indication.
The main functions like volume, source and mute can be remote controlled via your IR Remote (RC5 type or Apple Remote).
