A Sincere Thank You to ERCT | Dutch Audio Event
For the first time, we experienced an incredible weekend at Dutch Audio Event !
Mavis Lab would like to extend our sincere thanks to ERCT for bringing together an outstanding collection of audio brands and creating such an impressive experience across three exhibition and demonstration areas.
Our warmest thanks go to Cor and his wife for their wonderful hospitality, kindness, and enthusiasm throughout the event. We are equally grateful to the entire ERCT team for their friendliness, dedication, and tireless efforts in making every demonstration a memorable experience.
Congratulations to ERCT and all the participating manufacturers on the success of the event! The three demonstration areas presented a compelling showcase of different audio systems, each with its own character and approach to music reproduction. The impressive sound performances reflected not only the quality of the equipment but also the careful system matching, thoughtful setup, and dedication behind each demonstration.
A heartfelt thank you to everyone who visited the ERCT rooms, spent time listening to the systems, shared their thoughts, and showed genuine interest in the brands and products. Your enthusiasm is what makes events like this so meaningful.
We were also deeply impressed by Dutch Audio Event 2026 itself — the professionalism of the organizers, the scale of the exhibition, and the excellent environment created for audio brands, industry professionals, and music lovers to come together.
It was a pleasure to be part of this remarkable event, and we look forward to meeting music lovers again at upcoming audio shows throughout the remainder of 2026 and into 2027.

And others
The highlight of the system was the Master 15 Mark II, a two-way loudspeaker featuring a horn-loaded tweeter and a 15-inch woofer, complemented by Mavis’s latest subwoofer system, the MS12-600 Dual.
The MS12-600 Dual system consists of two S-212 subwoofer enclosures, driven by the SCM600 hybrid tube amplifier, specially designed and optimized to power these subwoofers.
Each S-212 enclosure features a dipole design incorporating two 12-inch drivers, bringing the total to four 12-inch drivers in the MS12-600 Dual system.
The Master 15 Mark II is driven by the Mavis P200 Power Monoblock, a transformer-coupled hybrid amplifier featuring a Single-Ended Class A Zero Feedback tube preamplifier stage combined with a solid-state power output stage.
Beneath its modest exterior, the P200 is truly a powerhouse, offering exceptional loudspeaker control and outstanding dynamic performance.
The MP1 is a tube preamplifier paired with the P200 in this system. Featuring an integrated MM-MC phono stage, the MP1 also handles the analogue playback, in combination with an AMG turntable.
Streaming music from Qobuz through the Mavis MMS-1, a transformer-coupled tube DAC Streamer, delivers high-resolution digital music with the exceptional refinement and musicality of vacuum tube sound.
“More is More” was the phrase used by HiFi.nl to describe the Mavis audio system demonstrated at Dutch Audio Event 2026 (Room 115 – ERCT).
- Why do we need so many subwoofers?
- Why does the Master 15 Mark II, already equipped with a 15-inch woofer having a great powerful capacity, still complemented by such a substantial subwoofer system?
- We have also received a related question: Why did we develop subwoofers when our loudspeaker models already deliver such a lively sound with their large 15-inch woofers?
Perhaps those who experienced the truly one-of-a-kind performance in the ERCT room late in the day (after 5:00 PM, as described in the review) already know the answer, without needing us to explain it in any further words!
However, “More is More” – just three words that truly sum up the answer to all the questions above!
We would also like to share below an excerpt from HiFi.nl’s review, describing the bass performance of the Mavis system at DAE 2026. It was a distinctive and impressive sound that the reviewer personally experienced while writing down these very observations!
This quotation also forms part of our answer to what makes the bass reproduction of the MS12-600 subwoofer system so unique.

“Hurricane-like volumes”
The concept of “bass you can feel” was given an entirely new meaning in Room 115.
The music sounded extremely dynamic, powerful and effortless, capable of reaching extraordinarily high sound pressure levels while retaining its finesse. If such words can be used to describe the sound at the hurricane-like volumes experienced in Room 115.
“Ferocious bass” was the final phrase that found its way onto my notepad, along with “unlimited processing power for impulses.”
And all of this was delivered by tube equipment.
Truly exceptional!
Many of those present were visibly thrilled in their seats; some even stood up to dance.
“Hurricane-like volumes” is not simply about playing music at high volume. Rather, it was described to be “The music sounded extremely dynamic, powerful and effortless, capable of reaching extraordinarily high sound pressure levels while retaining its finesse.“
This is a new definition of bass performance: a standard and a distinctive bass characteristic defined by exceptionally fast speed and extraordinary dynamics, while preserving the detail, refinement and openness of the other frequency ranges. More than that, it helps bring the entire frequency spectrum together, making the overall sound coherent, articulate and richly musical.
As a result, this system can excel with virtually every genre of music – from gentle and slow passages to the most demanding, fast-paced and powerful performances – while remaining faithful to Mavis Lab’s philosophy of natural, “like-live” sound.
Perhaps some certain musical pieces do not require such explosive speed and power. But this system is designed to offer much more than just satisfying listeners who prefer gentle and refined music. More is More!
If you also enjoy grand classical compositions – some of which feature the actual sound of cannons, as in Tchaikovsky’s 1812 Overture, or the mighty hammer blows in Mahler’s symphonies – or if you are a fan of rock, hard rock, electronic music, epic orchestral film scores or cinematic soundtracks, this system will offer you an entirely new listening experience, bringing you closer to the sound of reality.
Mavis Lab genuinely aspires to deliver the most complete, comprehensive and versatile musical and sonic experience possible, embracing every taste in music and sound.
We truly appreciate the diversity of musical expression and the richness of cultures reflected through music. Our ambition is to reproduce the true character and identity of every musical genre as faithfully and accurately as possible.
This, too, can be regarded as a way of experiencing music as it truly exists in reality – a genuinely live sound experience.
MORE truly achieves and delivers “MORE”!

(A translation of the review in English)
Room 115
Those who appreciate a dynamic sound can now turn to Mavis Lab. This Vietnamese brand – whose name stands for Master Audio Visual Solution – was founded in 2019 by Thi Nguyen and his wife, Joe Nguyen, and has also been part of the ERCT program since this year. Mavis Lab focuses on high-quality loudspeakers, tube amplifiers and hybrid amplifiers, which combine tube technology with transistor amplification. In addition, the company, based in Ho Chi Minh City, also manufactures horn loudspeakers.
A demonstration in Room 115 on Saturday, after 5:00 PM – beyond the show’s official closing time – began with Cor van Empel delivering an unusual and lengthy warning. In essence, he explained that the sound would become exceptionally loud, to an extent that might not appeal to everyone. Van Empel gave those present plenty of time to leave, but nobody did. He had already announced what was about to happen to a select group of attendees, and your reviewer had the impression that everyone sitting in the room had come specifically for the spectacle. And that is exactly what it was.
The system consisted of Mavis loudspeakers, driven by the MP1 preamplifier and a pair of P200 monoblocks. The latter are hybrid in two respects: tubes are used in the input and driver stages, while MOSFETs make the output stage powerful and stable. In addition, the P200 can be switched between Class A and Class AB operation.
The Master 15 Mark II is a two-way loudspeaker equipped with a 15-inch woofer for bass reproduction. Any reasonable person would think that such a driver should provide more than enough bass. But for the Vietnamese, it seems that ‘More is More’ is the guiding principle. That is why they also offer a subwoofer – the S-212 – featuring two 12-inch drivers and capable of reaching down to 18 Hz.
The Master 15 Mark II “satellites” (which are, in fact, substantial floorstanding speakers) reach down to 30 Hz. Naturally, ‘More is More’ also means using two subwoofers, so that stereo reproduction is maintained even in the lowest frequency ranges.
What is particularly interesting is that the subwoofers are passive. They are driven by a pair of SCM600 units (with SCM standing for ‘Subwoofer Control Masters’). This hybrid tube/transistor power amplifier is specifically designed for subwoofers and configured for mono operation, but it accepts a stereo input signal for enthusiasts who find a single subwoofer sufficient.
Hurricane-like Volumes
The concept of ‘bass you can feel’ took on a whole new meaning in Room 115. The music sounded highly dynamic, effortlessly loud and with very low distortion, while still retaining its finesse. That is, if such terms can be used to describe the hurricane-like volumes heard in Room 115.
“Ferocious bass” was the phrase that ended up on my notepad, along with “unlimited processing power for impulses”.
And all of this was delivered by tube equipment.
Truly remarkable!
Many of those present were visibly thrilled in their seats; some even stood up to dance.
