UBICUBE 700
MONO POWER AMPLIFIERS
Envisioned and conceived from the outset to handle the most demanding loads and drive the finest loudspeakers on the market.
UBICUBE 700
UBICUBE 700, UBIQAUDIOLAB chef’s kiss: a true ultra-high-end power amplifier, envisioned and conceived from the outset to handle the most demanding loads and drive the finest loudspeakers on the market. With uncompromising perfection in mind at every turn, a painstaking process of extensive research and development has led to an amplifier design with no cut corners and no slips into subjectivity, instantly transcending the notion of being just another amplifier.
The heart of UBIQAUDIOLAB amplifiers has been carefully refined through numerous iterations over the years; no stone has been left unturned in tuning, voicing, and optimization. Carefully implemented state-of-the-art electronic circuits, inspired by the finest classic topologies, have been extensively tested and refined down to the smallest detail, then elevated to a 21st-century standard to meet today’s extreme demands for dynamics and resolution. They have undergone extensive, rigorous listening tests and lab-grade measuring, using only industry-standard measurement systems at every step.
The UBICUBE 700 incorporates proprietary, boutique audiophile grade power modules, an engineering marvel – an ultrarefined approach with the shortest possible signal paths – that works seamlessly with an enormous, oversized yet highly advanced power supply. UBIQAUDIOLAB proprietary technologies enable UBICUBE 700 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 700 amplifier 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.
