What is stereo?




There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

Copland CSA-14 amplifier

The Integrated Amplifier CSA 14, combines the benefits of both valve and transitor amplification, in a way unheard of before, usually hybrid Amplifiers dedicate one section of the amplifier to valve in isolation from the rest beacuse, the virtues of solid state and valve design are not the same, a synergy between them can be created, offering an alternative to either.
The Copland CSA 14 uses two valves in the input pre-differential driver stage of the amplifier allowing the notably smooth and transparent properties of the valves to blend with the power and dynamics of transitor electronics.
The synergy achieved surpasses, the found in other Hybrid Amplifier, in its relability while combining only the positive attributes from each element. 
The CSA 14 is build into a slim compact chassis. With the same build and sonic qualities, that have always formed the cornerstone of Copland's philosophy, offering exeptional valvue, whist the design allows the listener to relax and enjoy the astronnishing sound quality.
Due to popular demand, Copland have simplified one of their high-end amplifiers, in this case the CSA 14, to provide a solid state produkt of real quality, at a point within reach of the aspiring audiophile.
