Copland
Where science meets art.
Founded in Denmark in 1984 by designer Ole Møller, Copland has spent four decades proving that valves and transistors are not rivals — they are complementary tools in the pursuit of musical truth. From the all-valve CTA 407 flagship to the hybrid CSA series, every Copland amplifier is hand-assembled in Denmark with a singular goal: to disappear, leaving nothing but music.
Philosophy
Copland's founder Ole Møller describes the paradox at the heart of audio design: how to scientifically approach a system that must perform as a medium of art. The audio designer, he says, is a performer of science and craftsmanship whose work must be carried out with artistic devotion. This philosophy has guided Copland since 1984 — choosing valves, transistors, or both, not out of dogma but out of devotion to the music. Where other brands pick a side, Copland picks what works.

Technologies
The innovations that make Copland products extraordinary.
Push-Pull Valve Output
Class A/AB purity from KT88, KT150, and beyond.
The CTA 407 runs pairs of KT88 beam tetrodes in push-pull ultra-linear mode with high-biased Class A/AB operation — most of its power is delivered in pure Class A. Three custom toroidal transformers provide isolated, ultra-clean power. The auto-bias system accepts any valve from the 6550/KT88/KT100/KT120/KT150/KT170 family without manual adjustment, letting you roll valves freely and tune the sound to your taste.
Synetic Hybrid Design
One valve. All the magic.
Copland's Synetic circuit — evolved since the early 1990s — places a single 6922 double-triode valve in the voltage-gain stage, running at high voltage for maximum linearity. MOSFET buffering bridges the valve world (governed by voltage) with the transistor world (governed by current), while a bipolar output stage delivers the brute force. The result is the organic dimensionality of valves with the grip, bass control, and reliability of solid-state.
Automatic Bias & Diagnostics
No matching. No fuss. Full visibility.
Every Copland valve amplifier features fully automatic biasing — the circuitry measures and adjusts bias current for whatever output valves are fitted, without any manual intervention. The CTA 407 adds a multi-colour LED diagnostic display: blue and green indicate healthy operation, orange signals increasing wear, and red means replacement is due. Swap valves in seconds, not hours.
Current Feedback Power Amp
Wider bandwidth. Faster transients.
Copland's solid-state and hybrid power amplifier stages use current-feedback topology — an inherently faster feedback structure than conventional voltage-feedback designs. The result is a wide, high-signal frequency response from 10 Hz to 150 kHz, exceptional transient speed, and stability into the most demanding loudspeaker loads down to 2 ohms.
