Artera Stereo

Two-channel power amplifier.

From the transformer to the input terminals, each section of the Artera has been engineered from the ground up to ensure power, musicality and stability.

The Artera Stereo produces 140 Watts RMS per channel – ample power for driving first-class loudspeakers, unfaltering even under high dynamic and transient conditions thanks to the patented Current Dumping technology.

Special attention has also been paid to the newly developed balanced XLR inputs. The robust connections are yet another string to the Artera Stereo’s bow, with an incomparable signal to noise ratio.

More Information



The history of Quad is one of technical achievement in the field of sound reproduction. It is a story that began with their first amplifier, which applied fifteen years of knowledge and experience in professional audio and industrial products to the task of making the most accurate domestic audio amplifier of its age.

Every product in the Quad portfolio of amplifiers, headphones, moving-coil loudspeakers and electrostatic loudspeakers have received international acclaim. However, Quad has never indulged in technical one-upmanship. Their technology exists for a purpose that has remained constant over the years - to reproduce music in a form that is the closest approach to the original.

Unilet Sound & Vision are one of the longest-established official Quad dealers in the UK, and one of only a handful of dealers for Quad Electrostatics in the entire country.
