"Music can change the world" [Beethoven]

                                                 ... and Contour can change how you enjoy the music.


Vista Audio Contour - front view

The simplest way to explain what Contour does is to say that it optimizes the interface between a source and an amplifier. The Contour provides stable input impedance and low output impedance thus eliminating potential mismatch between a music source and amplification stage. With gain close to 1 (0 dB) and vanishingly low distortion, the Contour does not change the sound quality of  the music reproduction system. For that reason we might call it an audio buffer.

The Contour ensures that every component in the system performs at its best.

However, there is more to the Contour than optimization of the source-amplifier interface. An active circuit has been designed to provide subtle improvements of the stereo imaging. A technically elegant solution helps every audio system to present a stereo image with better spatial resolution. The end result is clearer sound with more air and an apparent darker background free of cluttered artifacts. The Contour feels at home in all-analog systems and in high-resolution digital systems.

Conceptualized and thoroughly evaluated years ago, this design was waiting for the right moment to emerge as a polished, well-engineered Vista Audio product. Quality components packaged in a small-sized metal chassis make the Contour an easy and unobstructive fit in any system.

The Contour's user interface is straightofrward: the rear of the unit hosts the Power Switch (On/Off), two pairs of RCA connectors with line-level inputs/outputs (Input and Output) and Power Connector (PWR).

The Contour can be used in a simple system, inserted between a signal source (CD player, streaming device, phono preamplifier, etc.) and an integrated amplifier. In that case, one of the amplifier's  line-level inputs is used. Connections are made with good quality interconnects as illustrated below.

If a system consists of separate components the Contour can be inserted between a source and preamplifier. However, the Contour is more commonly inserted between the preamplifier and power amplifier, so that all the music sources can benefit from the  sound improvements. That scenario is shown here:

Of course, other combinations are possible, as long as the Contour's input is connected to a line-level output and its output is connected to a line-level input of the downstream component.

The Contour ships with a suitable power supply and we do not recommend leaving it on 24/7 as this wastes energy and does not contribute to sound quality - the Contour warms up quickly and reaches optimum operating conditions within 10-15 minutes. 

When powering up the system, it is recommended that Contour is  turned on first. After that, the standard turn-on sequence can be followed.

Last, but not least - put on some good music and enjoy!
