Burmester Hifi Compilation Bundle with Unison Research / Innuos

Musical enjoyment with character – warmth, elegance and technical precision

The gentle crackling of a fireplace, a comfortable armchair, a good glass of wine, and soft favorite music – this image is synonymous with relaxed music enjoyment. But even without a fireplace and red wine, the same holds true: only a perfectly matched hi-fi system can truly unleash the full magic of music.

AUDITORIUM expert Florian Kettenburg has put together an extraordinary combination for this experience:
The system consists of Burmester loudspeakers , the Unison Research S6 Black Edition tube amplifier , and the Innuos Stream 1 streamer as a digital source. The result is a system that perfectly combines warmth, naturalness, and technical finesse.

Unison Research S6 Black Edition – analog soul, digital diversity

The Unison S6 Black Edition is a high-end tube amplifier with state-of-the-art features. It has not only been visually redesigned but also technically enhanced. The integrated DAC allows for the processing of digital sources – such as a streamer or even a television. Thus, the S6 combines classic tube technology with contemporary functionality.

The precisely matched tube configuration, featuring Gold Lion tubes , two ECC83 triodes in the preamplifier, and six KT77 tubes in the power amp, delivers a sonic experience with a warm fundamental tone, rich bass, and harmonious musicality. The tube matching is particularly noteworthy – the left and right channels are precisely calibrated, guaranteeing maximum balance and purity of sound.

“The tube delivers exactly what you want: a full, warm sound that simply feels good,” said Florian Kettenburg.

Burmester B18 – Precision meets stage

The Burmester B18 loudspeakers perfectly complement the tube amplifier. Their exceptional dispersion characteristics and ability to create a wide, detailed soundstage make them the ideal partner.
In combination with the S6, its analytical clarity is embedded in a pleasantly rounded, warm overall sound – ideal for hours of relaxed listening without fatigue.

Innuos Stream 1 – digital source with perfect timing

The brand-new Innuos Stream 1 (market launch summer 2025) ensures precise digital signal transmission. Kettenburg is using the version with the Phoenix USB Output Module , whose integrated USB reclocker delivers the signal to the amplifier with absolute time accuracy and without distortion.
Since the streamer does not have its own DAC, the conversion takes place entirely in the Unison S6 – for the highest sound fidelity.

Innuos' intuitive Sense app also guarantees particularly user-friendly operation and is continuously being further developed.

Cables that connect – Transparent Cable

All components are wired with Transparent Cable . These cables are characterized by absolute neutrality – they neither color the sound brightening nor darkening it, but allow the interplay of the devices to be expressed in its purest form.

A soundscape for relaxation

This carefully selected combination offers music lovers a system for a truly enjoyable experience – warm, full-bodied, and balanced. Ideal for anyone who wants to listen to music in peace in the evening, unwind, and be pampered by both sound quality and aesthetics.
