Tokyo International Audio Show 2025
We arrived in Tokyo a few days before the show opened on 17 October, giving ourselves space to settle into the city before three full days of listening sessions. Those first days became a quiet highlight of the trip. As a team, we explored the city at an easy pace, enjoying the food, the atmosphere and the simple pleasure of being together outside the workshop.
We visited an izakaya named Chicken Kurokiya for a dinner that stayed with us — relaxed, down-to-earth cooking that reminded us why we love food as much as we do. We also made time for the Tokyo Skytree, the Museum of Contemporary Art Tokyo, Senso-ji Temple and Tsukiji Fish Market — for great omakase experience at Shutoku No. 3 store.
It was a good mix: art, views, history and some truly memorable food and drink. Those shared moments set a tone for the trip and gave us a sense of calm before the show began.
When setup day arrived, the room was already taking shape thanks to Zephyrn Inc. Led by Kohei and Motofumi, their team had assembled most of the system — CH Precision, Riviera Audio Laboratories, Wattson Audio, Crystal Cable and Artesania Audio — giving the space a strong foundation from the outset. Their preparation meant that we could focus on our part of the system: setting up Coltrane Supreme Extreme.
Working together — Jörgen, Leif, Martin and Lars — we positioned the speakers, aligned the cabinets and made the final adjustments that bring the model to life. Parker Trio Diamond Edition in white joined the system, providing a complementary contrast in scale and presentation.
Once everything settled, the system revealed its character quickly. Riviera’s amplification brought a calm sense of control, while CH Precision provided both transport and conversion — the D10 reference feeding the C10 DAC. With this combination, the digital front end shaped the full presentation, offering a clean and confident signal path that suited the room and the speaker perfectly.
Across the three days, the sessions found a steady rhythm. Visitors engaged with the system in that attentive, unhurried way we associate with Tokyo. We shared the story behind the project, discussed the new technology and listened alongside everyone in the room. Throughout the event, Yuriko Banno supported us as translator, ensuring conversations flowed naturally and nothing was lost in detail.
Our evenings were often spent with our partners after the doors closed — relaxed dinners that gave us time to unwind and enjoy good food together. Those gatherings were a reminder of how collaborative this industry is, and how much work goes on behind the scenes to make events like this feel effortless.
By the end of the final day, the room felt still and familiar. The second showing of Coltrane Supreme Extreme unfolded just as we hoped — grounded, collaborative and centred on music. It was a meaningful trip for us, both as a team and as part of a wider community of partners who care about high-performance sound.
Tokyo gave us space to connect, to listen and to carry the journey forward.
