Copland CTA 408

There is nothing like an excellent tube amplifier.

An amplifier that simultaneously offer a midrange that is open and clear, highs with an unconstrained mobility and acceleration, and a deep, tight and free flowing bass reproduction.

The Copland CTA 408 Integrated Amplifier is intended for those who prefer the ease of single chassis amplification, still wanting the performance of separates.

It offers such amenities as separate MC and MM phono inputs,

Monitoring in/outputs

Headphone amplifier and a startup procedure, that vastly prolongs the tube life.

During the last decades, advances in technology have offered new possibilities for circuit optimisation, using components and technology mainly unavailable for the previous designers of tube amplifiers.

Inside the Copland CTA 408 is one of the most carefully conceived tube amplification engines available.

Features Copland DTA 408

  • Driver stage tubes supported by MOSFET circuitry.
  • Numerous individual power supplies, designed to operate with constant power, thereby isolating power stage fluctuations from entering the input stages and eliminating reverse modulation towards the AC supply grid.
  • Dedicated Class A headphone amplifier, (speaker output mutes on headphone insertion)
  • Excellent J-FET- Phono-amplifier. Active RIAA equalization employing more than one hundred discrete components inside a noise-shielding box of its own.
  • The output transformers are Copland in-house design, fine-tuned for optimal power bandwidth.
  • The massive core size of the transformers prevents core saturation, and they are able to transfer full power well below 20Hz to the loudspeakers with a minimum of phase shift.
  • Multiple layers of interleaving wires ensures a superb linearity.
  • The extended high frequency performance reduces the requirements for internal lag compensation after the amplifiers 15dB negative feedback loop is closed.
  • The amplifier power plant is based on the KT150 power valves.
  • These valves are the latest variant of the legendary 6550/KT88 power valves and in the CTA408, they surely demonstrate that the everlasting sound qualities of tubes can be extended into regions nowadays dominated by solid stage designs.

The huge power tubes are very pleasing to look and therefore, we have decided to make them visible behind lateral perforations on the front panel, thus creating a stunning design to match the sonic virtues of this amplifier.

Copland is a Danish audio company that was established in the mid-1980s by Olé Möller. Their main product line include both valve and solid-state amplifiers. ... The first products were the CT401 and CT501 amplifiers, which won praise for their build and sound quality. The company also introduced a Digital Room Correction (DRC) system, which uses time-domain based techniques to generate anti-reflection signals to counteract room resonances and cancellations. It is based on Dynaton's DDRC module
