The 2026 Hong Kong High-End Audio Visual Show, which drew to a spectacular close on Sunday, August 9, saw Richcoln’s S429 demo room deliver an Italian audio feast that captivated the ears and hearts of countless audiophiles. Within this space, two prestigious Italian brands – Unison Research and Opera Loudspeakers – joined forces, presenting a comprehensive showcase that ranged from dynamic live demonstrations to exquisite static displays, fully embodying the passion, refinement, and unparalleled musicality of Italian audio craftsmanship.

At the heart of S429 was a meticulously curated reference demonstration system that embraced both analogue and digital sources. On the analogue side, the SME Model 8 turntable took centre stage, precisely extracting every musical nuance from the vinyl grooves; on the digital front, the Italian-made Lector CDP-707 CD player delivered the warmth of analogue-like reproduction from optical discs. Both sources were seamlessly connected to the front-end electronics using top-tier HMS cables from the Netherlands, ensuring pristine signal transmission.

The preamplifier duties were handled by the Unico Pre v2 in a striking gold limited edition – a component as visually dazzling as a work of art, whose pure Class‑A circuitry endowed the music with rich, full-bodied texture. The power amplification came from a pair of Unico DM v2 stereo power amplifiers, bridged into monoblock mode to transform into formidable mono powerhouses, each delivering a massive 650 watts (into 8Ω) to drive the Opera Grand Callas Special Edition flagship floor-standing loudspeakers with breathtaking authority. These speakers represent the pinnacle of Opera’s engineering – combining precision driver placement, reinforced composite cabinets, and proprietary crossover networks. Under the formidable grip of the Unison amplification, they unleashed a soundstage of remarkable width and depth, explosive dynamics, and exquisitely nuanced micro-details. Whether rendering the majestic tutti of a symphony orchestra or the intimate improvisations of a jazz ensemble, the system delivered a commanding presence and vivid realism that transported listeners to the front row of a concert hall, drawing spontaneous applause and acclaim throughout the show.

Beyond the captivating live demonstration system, S429 also featured an extensive static display that allowed visitors to take in the complete family portfolios of both brands at a glance.

In the Unison Research section, alongside the gold-finished Pre v2 and DM v2 used in the demo, an all-black version of the same pre/power amplifier combination was also exhibited, offering a more understated yet equally luxurious aesthetic to suit different tastes. The valve integrated amplifier lineup was nothing short of breathtaking: the Simply Italy Black Edition (pure Class‑A single‑ended parallel, delivering sweet and seductive tones), the Triode 25 Black Edition (switchable between triode and ultralinear modes for versatility), the S6 Black Edition (KT88 push‑pull design with abundant power), and the flagship Simply 845 (single‑ended 845 triode design, boasting magnificent and transparent sound). Each model, crafted with meticulous handwork and classic circuit designs, spoke passionately of Unison’s devotion to vacuum tube technology.

The Opera Loudspeakers section showcased a variety of models finished in elegant Rosewood veneer, ranging from bookshelf to floor-standing designs: the Mezza v.2 Rosewood, Prima v.2 Rosewood, and Callas Edizione Speciale bookshelf models, alongside the Grand Mezza v.2 Rosewood, Quinta v.2 Rosewood, and Callas Diva Edizione Speciale floor-standers. Every pair of speakers exemplified traditional Italian woodworking artistry, with graceful curves and a warm, tactile finish that transformed them into musical sculptures for the home, seamlessly blending auditory and visual aesthetics.

To give visitors a deeper appreciation of this Italian system’s true capabilities, Richcoln hosted three daily music demonstration sessions, each featuring guest appearances from senior editors of Hong Kong’s most authoritative audio publication “Audiotechnique”. The hosts not only delved into the design philosophies and technical highlights of each component but also curated a selection of audiophile reference recordings – from orchestral blockbusters to intimate vocal performances – rigorously testing the system’s powers of reproduction. During these sessions, the room was packed to capacity, with many enthusiasts choosing to stand rather than miss the opportunity to experience this “full Italian menu” in action. The lively post-demo Q&A sessions and enthusiastic audience engagement underscored the system’s tremendous appeal.

Richcoln’s S429 demo room undoubtedly stood as a pilgrimage site for European audio aficionados. From the soulful vacuum-tube warmth of Unison Research to the solid-wood resonance of Opera Loudspeakers and the pristine signal transmission of HMS cables, every element reflected the Italian dedication and romance for music reproduction. This was more than a product showcase – it was a heartfelt dialogue about the art of sound. For those who missed the show, the regret may only be resolved by next year’s event; but for those who were present, the rich, alluring Italian sound will surely linger long in their memories.
