CTA408 

The CTA408 Integrated Amplifier is intended for those who prefer the ease of a 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 has offered new possibilities for circuit optimization, using components and technology mainly unavailable for the previous designers of tube amplifiers.

Inside the CTA408 is one of the most carefully conceived tube amplification engines available.

• 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.

CSA 100

HYBRID INTEGRATED AMPLIFIER

The CSA100 integrated amplifier is a part of the latest work by Copland, aiming to combine the advantages of tubes and transistor amplification using the synectic design concept that previously has made Copland hybrid amplifiers widely acclaimed.

One tube is responsible for the CSA100 line amplification and the efficiency of this single tube layout is astonishing. The double triode tube runs at high voltage in a setup for maximum linearity, taking care of the voltage amplification only. A MOS-FET circuitry delivers the brute force driving the line stage output and feedback circuitry, thus securing a firm handshake between the world of electronic tubes governed by voltage and the current controlled transistor technology.

If you prefer the warm and nice colored charm of some older tube designs look elsewhere, the CSA100 tube line stage is made for monitoring. In this application the tube provides life, headroom and dynamics hard to find in amplifiers relying on solid stage technology only.

A single chassis machined from aluminium alloy to avoid magnetic interference. For the vinyl enthusiast the CSA100 has RIAA input for moving magnet or high output moving coil cartridges.The amplifier also employs an excellent D/A converter with multiple S/PDIF inputs, PCM, and DSD capabilities using the ES9018 Reference 32-bit DAC in quad-mono configuration, 8 mono to 2 stereo configuration.

The CSA100 USB input implementation is featuring  USB 2.0 PCM 24/32 bit data transfer to 384 kHz, including native DSD64 and high resolution DSD128.

The asynchronous USB-B port connects to your computer’s USB-A port. Once connected, the computer recognizes the CSA100 and routes the digital audio data to it, bypassing the source device’s internal audio circuitry.
