Ø Audio Icon


Ø Audio is made for us who simply just want to enjoy the music and forget about the rest!

We had long been looking for a pair high quality speakers that interested us a bit more than average, but after searching and searching without finding what we looked for we decided to make it ourselves.

Ø Audio Icon is the result of a few years with a lot of testing, building and measurements. We are very proud of the result and hope it can be of interest for other enthusiasts!

Our first only speaker model is called Icon.

Icon is made to be able to present the music in a precise, open and entertaining way. Our main goal when listening to music is to be able to just listen to the music without thinking about the speakers, amplifier, source or any other part in the setup.

High efficiency - Easy to drive

The Ø Audio Icon is a high efficiency speaker that is easy to drive even for low powered tube amplifiers. They are recomended to be used with amplifiers from around 8w depending on the setup and room size!

Asymetrical design

The Icon have a unique asymetrical design with no parallel walls. This gives very little resonances and also reduce the problems with reflecting soundwaves inside the cabinet.

Top of the line components

Ø Audio do only use top of the line components all they way in our products. We use custom designed woofers from Acoustic Elegance, Italian made compression drivers, Crossover components from Duelund and Jantzen and enclosure handcrafted in Poland.

Controlled Directivity

The Icon have a controlled directivity! The horn have a directicity of 60 degree horizontally, which is a bit more narrow than many other hifi speakers. This results in less reflections from sidewalls, which makes a better and more precise soundstage in most situations.

Trenner & Friedl Taliesin

This loudspeaker has its origin in the very first beginning of Trenner & Friedl.

Even before! More than 25 years ago, Andreas Friedl designed a very big (and we mean BIG) loudspeaker for his own use, a reference, a giant of joy.

When he and Peter Trenner founded the brand, Taliesin (the grey) stayed with Peter for many years. It was the benchmark for all coming loudspeakers.

Now the 25th anniversary is on the horizon, and the friends did not want celebrate without a Taliesin. The task was to make a worthy successor of the awesome forefather.

Nimbus Audio Arcus


The Arcus vacuum tube amplifier has been designed from the ground up to provide the discerning listener with an exceptional musical experience while remaining relatively compact and easily integrated into a living space.

In many cases, this approach would lead to a toned down version of higher-end separate components but not here: the Arcus was conceived with an uncompromising approach despite its compactness. A true dual mono supply, a precision resistor ladder volume control and a computer controlled power output stage that is capable of both Class A and Class AB operation put it in a category of its own.

With the combination of an all-tube amplification chain, very high quality components and an innovative feature set we're convinced that the Arcus amplifier will satisfy your highest expectations.


The Arcus amplifier uses only tubes and transformers in the signal path with no other active devices performing audio signal amplification.

The balanced inputs are handled by high quality amorphous core line input transformers, offering extremely good common-mode noise rejection over a wide frequency range.

Voltage and power amplification stages are connected through an additional interstage transformer using a push-pull topology with a precision current mirror for precise driver tubes biasing.

Finally, output power transformers connected in an ultra-linear topology provide the smooth and detailed sound signature of the Arcus amplifier.


One of the most distinctive capabilities of the Arcus amplifier lies in its ability to let the user select the supply voltage and bias current of the output stage through multiple tube profiles.

This feature allows the use of all tubes from the 6L6 family such as the 6L6,-G/A/B/C, 5881 or Russian 6P3S, and operate them in optimal conditions. Class A and AB profiles are also available providing complete tube operating conditions control.

The precise bias control also has the beneficial side effect of providing zero maintenance push-pull balance, thus ensuring the output transformer operates in ideal conditions over the entire tube lifetime.

Rounding up the flexible output stage, six WBT speaker binding posts offer the choice of two output impedance ranges: 4/8Ω or 8/16Ω, allowing optimal impedance matching.


For tube enthusiasts, the Arcus amplifier adds the ability to support signal amplification tubes using either 6.3V or 12.6V filaments. No manual adjustment is necessary and the correct filament voltage will be applied automatically based on the inserted tube.

This opens up the possibility to install new and NOS tubes from both the 6SN7 as well as the 12SN7 families, vastly expanding the usable NOS tubes range.

For the dedicated tube rollers, a simple Loctal to Octal socket adapter allows 7N7 and 14N7 tubes to be used for even more NOS tube options!


Designed as a no-compromises dual mono architecture from the ground up, the Arcus amplifier uses a separate power supply chassis housing dedicated power transformers for each channel.

In addition to offering fully DC regulated filament, high voltage and bias voltage rails, the power supply has been designed to limit RF interference from entering the circuitry through systematic use of common-mode chokes and filtering capacitors.

The end result speaks for itself: a pristine background for music to unfold on.


Contrary to many integrated amplifiers employing inexpensive volume controls, the Arcus deploys one of the most direct and transparent implementations: a relay-controlled precision resistor ladder volume control. The circuit uses low noise metal film resistors to offer volume control in 1dB steps with almost perfect channel matching.

For ultimate user convenience, during volume changes the audio path is switched to a professional grade VCA (voltage controlled amplifier) circuit enabling smooth and continuous volume adjustment until the desired sound level is reached. Once this is done, the pre-amplifier ciruitry will switch the audio signal back to the passive volume control.


​Vacuum tube only signal path with inter-stage and output transformer coupling and no negative feedback.

Push-pull drivers and push-pull ultra-linear output stage with choice of Class A or AB operation.

Computer controlled, analog tube bias control and voltage control with user-selectable tube profiles.

Precision current sensing for perfect push-pull bias current balance requiring no manual adjustments.

Transformer coupled balanced audio inputs feeding a hybrid resistor ladder volume control / analog VCA.

Nagra HD Preamp

Nagra HD Preamp will debut at Tokyo Show, Vietnam Show and RMAF 2017.

"Almost 20 years after the release of the mythical preamplifier Nagra PL-P in 1998, Nagra will introduce at RMAF 2017 one of the most ambitious project of its history, the HD Preamp.

For the past three years Nagra R&D Department, served by ten skilled and specialized audio engineers, worked on that project with the goal of creating the most revealing and engaging preamplifier in the world. This tube base dual-mono spared no expense or experimentation in the fields of electronics, mechanics, power supply, thermal issues and obviously extensive listening sessions. The result is a striking product in terms of specification and performance. It will just reshape the expectation you may have of a preamplifier or your whole set-up, sources and amplifiers…

Volume control is a patent pending technology that allows perfect level match and is much superior to pots and switch resistors.

Suggested retail €54´900
US Retail price $59.500.

Aequo Audio Stilla

Stilla is a very small and elegant floor standing speaker, yet it has the same output above 20hz as the Ensis. Responsible for this challenging job are two 7" subwoofers mounted inside the horn loaded bass reflex cabinet, powered by Ncore amplifiers.

The active electronic system for analog room size and placement correction is used to tune the speaker to roll off as a closed box speaker, so it does not suffer from problems normally associated with ported speakers.

Many other technologies and materials of the Stilla are more directly derived from the closed-box Ensis speaker and the Stilla is equipped with the same formidable midrange driver. The result is a comparable character with rich audiophile musicality as well as transparent uncoloured precision and an amazing  holographic soundstage.

The middle and high frequency section of this hybrid speaker remains passive. Specified as 8 ohms nominal and highly sensitive, it is made to work well with a wide range of amplifiers. The 5" driver is responsible for a very open, or pleasantly detailed, midrange frequencies without coloration. It is accompanied by a tweeter system with a concentric dome and ring moving-surface, as well as some new dispersion-improvement technologies.

The two transducers are time-aligned by the carefully sloped cabinet, and wideband phase-aligned by the low-order crossover.

Boulder 3010 Preamplifier inside

Kerr Acoustic True Ribbon Tweeter

We feel that ribbon tweeters are an area often shrouded by misconception. While the term ‘ribbon’ is used to cover a broad range of tweeter technologies, a ‘True Ribbon’ tweeter is one in which the whole diaphragm itself acts as the conductor. This means there is absolutely zero excess (non-conducting) mass, and that the diaphragm can be immensely thin and light.

The aluminium ribbon diaphragms used in our K300 monitor are just 15 microns thick, and have a total moving mass of 0.027g.

For context, air-motion-transformer tweeters typically have a moving mass of 0.17g, and conventional dome tweeters around 0.5g. From this, you can gather that our ribbons are approximately eighteen times lighter than most domes!

The result? Flawless reproduction of high-frequency content, and unmatched transient response. The speed, extension, and non-fatiguing detail that our tweeters provide is quite remarkable, and make it very hard to switch back to conventional tweeter designs.

We use True Ribbons throughout our range of products.

Technics SP-10R

SP-10R use a new coreless direct-drive motor with a two-sided rotor drive system and stator coils on both sides of the rotor. The platter, like that of the SL-1200G, is a sandwich of brass, die-cast aluminium and rubber.

The platter weight is 7,85kg and the inertial mass is 970kg-cm2.

The SP-10R also features a new ultra-low-noise switching power supply in a discrete unit, separate from the turntable, to prevent cartridge hum.

As with the original ’70s SP-10 models, the core SP-10R doesn’t come with a plinth or tonearm, although Technics will also be selling a complete package that includes those items.

The Technics SP-10R will be available from early summer 2018.
