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.

Copland CSA-8 amplifier

The CSA 8 incorporates just three controls for input, audio level (which remains calibrated in db steps) and an on/off switch. Advanteges can be gained of cause by reducing the controls, enabling the shortest and most direct signal path for a clean sound. The input selection caters for tuner, CD and AUX 1.

The valves have been replaced with an solid dtate circuit creating the most significant change in price and nature of the sound, but not in the quality itself. The sound stage has been brought forward as in transistor amplifiers, yet the smooth character attributed to Copland has been retaned.

Copland CDA 823

The CDA823 is an evolution of the renowned CDA822 CD-player. While employing the same outstanding DACs and analog amplifiers as its predecessor, double resampling and reading speed are now introduced. Increased over-sampling of 192 kHz is used to avoid the loss of energy and transparency in a complex analog output filter. The CDA823 also allows for future updates of firmware through flash programmable microprocessors.

The CDA823 uses a true 24-bit, high-resolution, dual differential, digital to analog converter with current output for widest dynamic ranges, fast conversion and lowest noise. Jitter distortion arising from time errors is virtually eliminated by sample rate converters and our precision internal master-clock. All audio power supplies are multi-regulated. The output amplifiers are a priority in the design of this audiophile CD-player. Operational amplifiers with their fixed working conditions and sound qualities can become an obstacle when the designer wants to be in control of the final performance. Therefore, CDA823 employs discrete class-A input amplifiers with carefully selected operational points for the specific electronic environment in which they have to perform. The output circuitry provides both fully balanced and single ended outputs.
