The arguments about the relative merits of tubes, MOSFETS and bipolar devices have filled many technical journals, and needless to say, most are over stated and over simplified to try to win the argument! It’s possible to design a good amplifier using any of the available technologies. Turning it into a great amplifier takes more than just a good argument. In the Klimax we chose bipolars running in Class AB and put in the essential circuitry to take maximum advantage of the inherent linearity of bipolars (unlike MOSFETS), and to manage their potentially slower switch off characteristic. Many MOSFET designs neither adequately linearise the MOSFETs, and in the assumption that ‘they are easy to drive’ don’t put in adequate circuitry to take advantage of their potential switch off speed. However, if we ever decide to make an amplifier above 500 Watts we would most probably use MOSFETs.

To run a system of amplifiers of the Klimax power in Class A would heat a house, very expensively, after laying in a high current three phase mains supply to the house. So we chose to use Class AB with the circuitry necessary to control precisely the handover from one power device to the other.

To avoid having capacitors in the audio path the Klimax is direct coupled with a dc servo to minimise output offset voltage.

500 Solo specifications

The Linn 500 Solo is a high-performance loudspeaker that exemplifies the brand's commitment to audio excellence and innovation. Building on the heritage of Linn's acclaimed speaker systems, the 500 Solo was designed to deliver an immersive sound experience for both music enthusiasts and casual listeners alike.

One of the standout features of the Linn 500 Solo is its active design, which utilizes a dedicated amplifier for each driver. This configuration eliminates the need for passive crossovers, allowing for greater precision in sound reproduction. By amplifying the signal directly at the speaker, the 500 Solo can provide a more accurate and dynamic range, showcasing the subtleties of the music without distortion.

The speaker is equipped with advanced driver technology, including a high-performance bass driver and a specially designed tweeter. The bass driver features a large, lightweight cone that delivers deep, controlled low frequencies, while the tweeter is engineered to reproduce high frequencies with clarity and detail. Together, these drivers create a well-balanced sound signature that is suitable for a wide variety of music genres.

To further enhance sound quality, the Linn 500 Solo incorporates cutting-edge digital signal processing (DSP). This technology allows for real-time adjustments to the audio signal, compensating for room acoustics and ensuring that listeners experience the best possible sound profile, regardless of their environment. The integration of DSP also allows for customizable sound settings, enabling users to tailor their audio experience to their preferences.

The build quality of the Linn 500 Solo is another hallmark of its design. Constructed with rigid cabinet materials, the speaker minimizes resonance and vibration, which can negatively impact sound quality. Additionally, its aesthetically pleasing design is available in various finishes, allowing it to blend seamlessly into any home decor.

Connectivity options are also a strong suit of the 500 Solo, featuring built-in streaming capabilities that support a range of digital audio sources. This functionality allows users to connect wirelessly to their music libraries and streaming services, providing convenience and versatility in audio playback.

In conclusion, the Linn 500 Solo is a remarkable loudspeaker that showcases the brand's dedication to sound quality and innovation. With its active speaker design, advanced driver technology, and customizable digital signal processing, the 500 Solo stands out as a premium choice for audio enthusiasts seeking an exceptional listening experience. Whether used in a dedicated home audio setup or as part of a larger music system, the 500 Solo offers unparalleled performance and style.
