The New Reference Preamplifier
Since 1998, the Jubilee preamplifier, with its careful refinements, has represented the sonic pinnacle of Octave preamplifiers.
Now it has been surpassed once again by its successor from the latest generation, the Jubilee Preamp SE.
Optimized in key sonic and technical aspects, subtly improved in detail, perfected in its user interface, and with an expanded range of functions, the new Jubilee Preamp SE proudly takes its place as the new leader in Octave technology.
Technology
While the revolutionary amplifier layout of the original Jubilee Preamp was already groundbreaking in terms of sound, technology, and aesthetics, the Jubilee Preamp SE takes things to a whole new level.
It naturally retains the unique features of the first generation Jubilee Preamp, which can be summarized as follows:
- The precision tube-based balancing stage ensures a perfectly balanced signal for the power amplifiers
- The discrete solid-state output stage enables the Jubilee Preamp to deliver an extremely low-impedance output with very high current capability.
- The zero-feedback circuit design, a highly sophisticated concept, rewards the listener with unwavering stability and exceptional detail
Detail-oriented improvements, made possible only through years of experience with numerous top-of-the-line combinations, have led to optimizations in the XLR input. Here, highly advanced input transformers, manufactured in-house, are used, specifically designed for modern DACs with high output levels up to 8V RMS. Their typical extended frequency and dynamic range is also effortlessly covered. These transformers are characterized by an input impedance of 80 kΩ and a frequency range of 5 Hz to 150 kHz. The total harmonic distortion (THD+Noise) of these transformers is 0.005%. Here, every DAC performs at its best. Any impairment of the high-quality music signal is 100% impossible, as no transistor input stage with its inherent nonlinearities—however small—affects the music signal.
External Power Supply
In combination with the newly developed, vacuum encapsulated low-noise supply-voltage stabilizing circuitry, the separate, magnetically shielded, outboard power supply of the Jubilee Preamp SE (essential for the low-noise and low-hum function of the MC-input) ensures constancy of the audio output even when the mains voltage is subject to wide fluctuations and high interference levels. Added to this, the integrated control logic system guarantees maximum operational reliability and, backed by our exclusive soft-start technologies, ensures the tubes and the unit have a life of up to twenty years.
