Adaptive Bias Control Klimax Solo 800 features our original Adaptive Bias Control technology. With it, we establish the ideal bias current for each of the amp’s sixteen output transistors dynamically and in real-time by measuring, sampling and digitising the current supplied to them. A digital control loop then implements and persistently adjusts this optimum bias current for each individual transistor specifically; negating crossover distortion at any temperature – regardless of volume or demanding dynamic changes in music – for the entirety of the amp’s life.
アダプティブ・バイアス・コントロール Klimax Solo 800 は、当社独自のアダプティブ・バイアス・コントロール技術を搭載しています。この技術では、16個の出力トランジスタに供給される電流を測定、サンプリング、デジタル化することで、各トランジスタに理想的なバイアス電流をリアルタイムでダイナミックに設定します。 デジタル・コントロール・ループは、この最適なバイアス電流を個々のトランジスターに特別に実装し、持続的に調整することで、音量の大小や音楽のダイナミックな変化に関係なく、アンプの寿命が尽きるまで、あらゆる温度でクロスオーバー歪みを排除します。
Cool Runnings Klimax Solo 800 features superb heat management; driving the most difficult of loads without compromising linearity or resorting to an internal fan. Excellent heat coupling is achieved by mounting the amplifier and power supply circuitry directly to the critically efficient, large surface area heatsinks. This cool-running design is key to delivering exceptional clarity right up to 800W into 4Ω, and 1.2kW into 2Ω. Temperature is minimised within the amp, ensuring that the properties of its internal components remain consistent during even the loudest and most demanding passages of music. It maintains consistency, efficiency and longevity at all times.
クール・ランニング Klimax Solo 800 は、リニアリティを損なうことなく、また内蔵ファンに頼ることなく、最も困難な負荷を駆動する優れた熱管理を特徴としています。 優れた熱結合は、アンプと電源回路を非常に効率的で表面積の大きいヒートシンクに直接取り付けることで達成されています。このクール・ランニング・デザインは、4Ωで800W、2Ωで1.2kWまで卓越した明瞭度を実現する鍵となります。 アンプ内の温度は最小限に抑えられ、大音量で最も要求の厳しい音楽でも内部コンポーネントの特性が一定に保たれます。常に一貫性、効率性、長寿命を維持します。

NATURAL MATERIALS COMBINE FOR THE ULTIMATE SONIC EXPERIENCE
Each material was selected for its unique qualities.When combined, they complement and enhance each other’s strengths. Suprema uses carbon fiber for its exceptional resistance, wood for its harmonic qualities, and solid aluminum CNC specifically machined for its static qualities.
INNOVATION IN FULL BLOOM
While the use of natural materials is a hallmark of Sonus faber tradition, the electro-acoustic design has been completely reimagined. The new Camelia midrange, responsible for the most important part of the acoustic spectrum, was developed to ensure maximum resolution, while maintaining the signature Natural Sound of Sonus faber. The form of the new membrane is inspired by the camelia— a prized flower in the region of Tuscany. Its shape is not masked by suspensions and avoids the formation of resonances typical of circular shapes
NEW DUAL DRIVE MAGNETIC SYSTEM
Control and dynamics are secured by the new dual drive magnetic system. The air flow management is held by the organic basket, a Sonus faber original design first implemented on Stradivari woofers.
CORK INTERNAL VOLUME
The special combination of tweeters and midrange are loaded into a unique chamber dedicated to internal volume, designed to enhance the performance of the drivers. Obtained through the use of a computer simulator, the result is a purely organic shape, without regular interior walls and built in a new, natural and sustainable material: cork. Sonus faber can proudly claim to be the first to use recycled cork to create acoustic volume. The acoustic properties of this material play a fundamental role in the resolution and natural quality of the midrange performance.
THE SUPREMA SUBWOOFER
For the best reproduction of infrasonic frequencies, a separate subwoofer system has been engineered to optimize the low range response based on the listening environment, regardless of the position of the main columns. The Suprema Subwoofer uses two powerful 38cm transducers, featuring forged carbon fiber membranes and a neodymium magnet motor system to ensure undistorted pressures up to 16hz.
THE CROSSOVER NETWORKS
These cutting-edge filters, sleekly visible on the sides of the main column, embody a decade of electroacoustic expertise. Sonus faber meticulously crafted Suprema’s tonal perfection through simulations, tests, and listening sessions, ensuring impeccable soundstage performance. The Suprema’s integration with subwoofers is managed by a dual mono, fully balanced electronic crossover. Suprema’s ground coupling control, in collaboration with IsoAcoustics, achieves exceptional dynamics and power while preventing unwanted vibrations.
POLTRONA FRAU LEATHER In keeping with our brand’s tradition, the front panel is adorned with luxurious leather, a collaboration with the esteemed Italian luxury forniture brand, Poltrona Frau. Each set of Suprema speakers will showcase distinctive Poltrona Frau’s Pelle Frau® Impact Less leather, a chromium-free tanning process leather launched in 2022.
It has the most sophisticated and uncompromising amplifier design in our amplifier hierarchy and sets a new benchmark for state-of-the-art power amplifiers. It features a number of detailed improvements including the use of eight KT 170 tubes with 440 W per channel. The basic idea of the Ultimate series is the extreme expansion of the power bandwidth and the bass range with our highly specialized (newly developed) and oversized high performance output transformer.
The Jubilee Mono Ultimate thus achieves the beauty of playback as it should be: intense, emotional and incomparable
DESCRIPTION
The Jubilee Mono Ultimate: not an evolution, a revolution.
Octave is proud to introduce the revolutionary successor to its flagship Jubilee Mono SE amplifier model: the Jubilee Mono Ultimate, the new flagship of the Octave power amplifier range.
In 2000, the first Jubilee Mono represented a milestone for high-end tube amplifiers with an output of 250 W, immense power reserves and Octave Power Management for rock-solid performance and reliability. In 2016, design and performance were improved with the introduction of the Jubilee Mono SE (Special Edition) further developed: Eight KT 120 tubes generated an output power of 400 W per channel.
Now, in 2023, it was time for a new development: The Jubilee Mono Ultimate is the most sophisticated amplifier design in the company’s portfolio to date and features a variety of new technologies including eight KT 170 tubes with 440 W per channel and a gigantic “super transformer”.
The basic idea of the Ultimate series is the extreme expansion of the bass range or the power range.
This expansion into the seemingly inaudible frequency range radiates into all other hearing areas. Although not immediately obvious, the critical midrange in particular benefits significantly from a deep and precise bass foundation. The influence that the lowest, almost inaudible low bass range has on the musicality of the midrange is significant. This basis enables the physicality, the spatial depth and the ebb and flow of the musical elements – as is the case with live music. Even more details on how we got there: For most amplifier designs, an increase in power bandwidth is usually associated with an increase in distortion. Andreas Hofmann, Octave founder and chief designer, has developed a completely new output transformer and a new, complementary driver stage for the Jubilee Mono Ultimate, which virtually eliminate this effect and therefore enable an unsurpassed dynamic range. This is a path that no one can tread like Octave, as we have been designing and manufacturing bespoke transformers ourselves for decades, using our own technologies. This allowed us to develop an oversized output transformer for the Jubilee Mono Ultimate with the necessary power bandwidth of 10 Hz to 100 kHz, with virtually no increased distortion. This was achieved, among other things, by using a special wrapping technique to counteract the skin effect, which degrades the characteristics of the upper frequency range.
For example, the speaker windings of the output transformer more than doubled compared to normal designs, increasing the surface area of the windings by 50%. This winding technique contributes significantly to the incredible resolution and smoothness that characterizes the Jubilee Mono Ultimate in the mid and high frequency range. Otherwise, we use four transformers that were specially developed for the Jubilee Mono Ultimate: the gigantic output transformer, a separate transformer for the power tube heater and a double line transformer system for the power section of the power amplifier. In the heavily modified driver stage, Andreas Hofmann addressed, among other things, the problem of exact phase relationships: the more precisely phase and anti-phase are generated and amplified in a push-pull power stage, the better the power stage works in the bass and especially in the treble. We have come a big step closer to the ideal of this amplifier principle. Together with the expansion of the performance range, the new driver stage represents a new development approach in the spirit of “No Loss of Fine Details – without Limits”.
In every respect, the Jubilee Mono Ultimate achieves a beauty of sound reproduction that rivals the sound of a single-ended power amplifier, but without the inherent limitations that such designs impose. With the Octave Jubilee Mono Ultimate you can experience music the way it should be – intense, emotional and unforgettable.
