"... superb-sounding system with a solid bass foundation that never stepped out of line; the midrange is superb, allowing each instrument to have air and space, and the treble comes across detailed and controlled without sounding sharp. We got to hear Ratchet at a decent volume, and the whole room was moving, I mean, this is true trouser flapping bass ..."

Music is Emotion. Reproduction is Science.

At hARt Lab, we believe that great audio is born when engineering serves the emotional power of music. Precision, transparency and technical excellence are not goals in themselves; they are the means to bring you closer to the performance.

We invite you to experience this philosophy at the HIGH END 2026, from 4–7 June, in Room 3.86 of the Austria Centre Vienna.

Together with Aretai Audio, we will present the Northern Sound concept, featuring the Tune Two preamplifier, Tune Three power amplifier and Tune Six integrated amplifier driving the remarkable Contra 200F loudspeakers.

Join us and discover how Northern precision meets Mediterranean soul in a system designed to reveal both the science and the emotion of music.

Northern precision meets Mediterranean soul with a Far East connection!

We are delighted to join Aretai Audio in presenting the Northern Sound concept at the upcoming High End Society show in Vienna.

The system will feature our Tune Two preamplifier and Tune Three power amplifier combination, alongside the Tune Six integrated amplifier, which will drive Aretai's impressive Contra 200F loudspeakers. Complementing the system will be a magnificent turntable from Clearaudiohifi, a modern classic reel-to-reel tape machine from Revox and an Anniversary Streamer-DAC from Aurender. All components will be connected through Athenamuse cables and supported by MW Stands.

The Northern Sound concept reflects a shared philosophy between our brands: authentic musical communication, technical refinement, and a focus on long-term listening enjoyment rather than spectacular short-term effects. It is an approach that values natural timbre, coherence, dynamics and emotional engagement; the qualities that transform reproduced sound into a genuine musical experience.

We look forward to welcoming visitors to discover how Latvian loudspeaker craftsmanship and Greek amplifier design come together through a Korean connection to create a compelling and distinctive listening experience.

See you in Vienna!

🇦🇹🏬 𝗡𝗲𝘄 𝗰𝗶𝘁𝘆. 𝗡𝗲𝘄 𝘃𝗲𝗻𝘂𝗲. 𝗔 𝘄𝗵𝗼𝗹𝗲 𝗻𝗲𝘄 𝘄𝗮𝘆 𝘁𝗼 𝗲𝘅𝗽𝗲𝗿𝗶𝗲𝗻𝗰𝗲 𝘁𝗵𝗲 𝗛𝗜𝗚𝗛 𝗘𝗡𝗗 𝗮𝘂𝗱𝗶𝗼 𝘀𝗵𝗼𝘄.

For the first time, the 𝗛𝗜𝗚𝗛 𝗘𝗡𝗗 𝟮𝟬𝟮𝟲 takes place at the Austria Center Vienna - and that means more than just a change of address:

𝗩𝗶𝘀𝗶𝘁𝗼𝗿𝘀 can look forward to a venue designed to make the show easier, more comfortable and more exciting to explore: modern listening rooms, open hall concepts, improved navigation and five levels filled with audio brands, live demos and discoveries around every corner.
More space also means more possibilities. More systems to hear. More exhibitors to meet. More places to sit down, listen and spend time with music.

And for 𝗲𝘅𝗵𝗶𝗯𝗶𝘁𝗼𝗿𝘀, Vienna offers a strong new setting, too: a well-connected international city with excellent infrastructure, short distances and a wide choice of hotels close to the venue and across the city.

Once the show day ends, Vienna itself becomes part of the experience. One of Europe’s greenest and most livable cities, it invites visitors and exhibitors alike to explore legendary music venues, cozy coffee houses, rooftop bars and riverside evenings along the Danube. 🎶

If you’ve been to HIGH END before, expect a fresh new atmosphere.
If you’ve never been, 2026 might be the perfect year to start!

We’re honored to see hARt Lab featured at AXPONA 2026 through the efforts of our US distributor, AudioThesis.
The simplicity of the system and the philosophy behind the Tune Six Super Integrated combine musicality, power, and versatility in a single chassis.
Thank you, Part-Time Audiophile, for the thoughtful coverage and for taking the time to listen.
Sometimes the biggest upgrade for a loudspeaker is not replacing it, but driving it with a better amplifier.
