About product

More power, more control and even lower distortion.
Supported by the new “switched mode” power supply technology the soulution 701 mono­amplifier sets new standards in for uncompromising music reproduction and out­classes its predecessor the soulution 700 by far. Colossal power and breath taking performance. Never has an amplifier been so close to perfection, but at the same time the technology must be subordinate – and transparent – to the music. Letting you experience music in all its natural diversity and beauty.

Key features:

  • Audio grade “switched mode” power supply (4 × 600 VA )
  • More than 1,000,000 µFarad storage capacity in the power supply unit
  • Peak current rating of more than 120 Ampere
  • Impulse power rating > 12,000 Watt


Two amplifier channels can be used either in mono-mode or in dual-mode. They work perfectly load stable and 100% level and phase accurate like in the soulution 711 with shortest signal paths and no excessive open loop gain as often associated with solid state amplification. The soulution 701 mono­amplifier is an ultra-fast and ultra wideband design (2 MHz/– 3 dB) and provides peak current ratings that would never be possible with a tube design. The unique concept of the soulution 701 mono­amplifier combines seemingly contradicting qualities. Precision, Velocity, Stability and Power. The soulution 701 is closest of all to this ideal. As monoblock design it is capable of up to 1,200 W of continuous power (into 4 Ω) and more than 12,000 W of transient power. More than enough to breathe new sonic life into even the most demanding, low-efficiency loudspeakers.

To deliver these impressive power levels we have used bridged amplifiers. Optimized mech­anical construction ensures both amplifier circuits are perfectly balanced, sharing identical thermal conditions and ideal grounding. When no music is playing an intelli­gent control system auto­matically lowers the quiescent current. And when loudspeakers dictate bi-amping, the soulution 701 mono­amplifier can be easily switched to this mode. We think of it as tailor-made amplification.

Power supply
The new power supply of the soulution 701 mono­amplifier is based on audio grade “switched mode” modules. Four units with 600VA each combined with highend storage capacitors (> 1,000,000 µFarad) provide enough power reserves that allow the 701s reproduce even very complex music signals with ease. Circuitry that does not process audio signals should not be able to influence them. That’s why we use dedicated power supplies within each mono­amplifier for the ancillary stages.

Power, mode and input functions are operated from front panel buttons. Power toggles between on and off states. Mode transfers control of turn-on to an associated preamplifier via soulution’s LINK system. Input selects the desired input and mutes the others.

Connectors and start-options
The monoamplifier 701 does have balanced and unbalanced inputs. With the balanced connection the input signal can be bypassed to another amplifier. Switches at the back of the amplifier allow to define the start options for the brightness of the display, the start-condition of the amplifier and the operation mode (mono or bi-amping).

About brand


Soulution is owned by the Spemot corporation, a company located in the Swiss town of Dulliken. Spemot is a well-established designer and producer of electronic devices and electric motors used in automotive and other applications including professional catering equipment. The company has a strong track record in innovative bespoke solutions that meet specific customer needs.

The soulution brand for premium audio was created by Spemot’s two managing directors Cyrill Hammer and Roland Manz, both of them passionate high-end audio hobbyists. The pair are long-time Swiss distributors of the Hi-Fi & Records magazine. Having owned and heard top amplifiers produced by US and Japanese manufacturers, they resolved to lay down a challenge and build a family of audio products that would set a new and even higher benchmark.

As reviews of soulution products by audio magazines around the world testify, Hammer and Manz have achieved their goal.


The outstanding sound qualities of the soulution products should also be supported by the design of housing, both visually and by their construction. Due to their size it was clear that they must integrate optimally into a listening/living room to be enjoyed not just for their sonic beauty but as well for their visual appearance. The development of the housing design was therefore carried out with the same care and professionalism as the development of the electronics. Several proposals were made which fulfilled both the technical requirements for stability and heat dissipation, as well as the design requirements.

Design Awards

The effort has paid off. The soulution products were awarded several times for its timeless and elegant design by international design juries.
