UBICUBE 400
UBICUBE 200
MONO POWER AMPLIFIERS
Envisioned and conceived from the outset to handle the most demanding loads and drive the finest loudspeakers on the market.
UBICUBE 400 / 200
Like its gigantic sibling, the UBICUBE 700, the UBICUBE 400 amplifier delivers the same uncompromising high-end audio performance in a slightly smaller form factor, meeting the needs of listening rooms where the gargantuan UBICUBE 700 is too large.
Following the same principles and spirit, the UBICUBE 200 mono amplifier is built on the essence of the UBICUBE 700 and UBICUBE 400, yet further optimized to perfectly drive even the most demanding, highly efficient, state-of-the-art speakers from 97 dB onward. The UBICUBE 200 focuses on purity and minimalism.
The UBICUBE 200 and 400 incorporates proprietary, boutique audiophile grade power modules, an engineering marvel – an ultra-refined approach with the shortest possible signal paths – that works seamlessly with an enormous, oversized yet highly advanced power supply.
UBIQAUDIOLAB proprietary technologies enable UBICUBE 200 and 400 to access an infinite density of acoustic information, revealing the most subtle, feather-light nuances of the human voice and acoustic instruments, the smallest portions of reverberation tails, and the tiniest taps of ambient echoes, with music emerging from submarine, absolute-black depths.
At all times, the UBICUBE 200 and 400 amplifiers delivers unaltered, perfectly consistent, lightning-fast, on-demand power, ready to adapt to any type or genre of music, never faltering even with complex music material such as thunderous orchestral compositions, highly demanding modern hybrid film scores, or intricate electronic productions.
In line with UBIQAUDIOLAB’s ethos of putting musical performance and music first, these unique technologies ensure a complete absence of distortion, listening fatigue, and sonic signature, allowing the music to command the listener’s attention and instantly ignite one-of-a-kind emotional engagement and interaction.
