A power amplifier that effortlessly combines control and refinement: the Solution 311. Designed and built in Switzerland according to the same uncompromising philosophy as the larger models, but in an elegant and more compact format.
The 311 proves that strength and finesse can go together perfectly.
Design and technology
The Solution 311 uses a fully balanced structure, an extremely fast amplifier architecture and a very powerful, stable power supply. This creates an exceptionally linear and controlled behaviour, regardless of the load.
Thanks to the wide bandwidth and low distortion, the music signal remains intact, without compression or colouring. The amplifier reacts instantly and accurately, with impressive control over even tricky speakers.
Sound character
What is immediately striking is the calmness and self-evidentness with which the 311 music presents. No emphasis, no appeal, but an open and transparent sound image in which everything is right.
The stereo image is large and stable, with a clear placement of instruments and voices. Dynamics are displayed effortlessly, from subtle nuances to powerful impulses.
The combination of speed, control and neutrality makes this amplifier an ideal partner for high-quality systems in which detail and musicality are central.
