Amplifiers
Pure valve, hybrid, and solid-state amplification
From the all-valve CTA 407 flagship with its KT88 push-pull output stage to the CSA hybrid series combining a 6922 double-triode with MOSFET and bipolar transistor power, every Copland amplifier is designed by Ole Møller and hand-assembled in Denmark. Built-in DACs, MM phono stages, and headphone amplifiers make each model a complete system hub — while the current-feedback power stages drive any loudspeaker with authority and finesse.
Three Topologies, One Voice
Pure valve (CTA), hybrid valve/MOSFET (CSA 100/150), or refined solid-state (CSA 70) — Copland uses whichever topology serves the music best.
Auto-Bias & Valve Rolling
Fully automatic biasing accepts KT88, KT120, KT150, KT170, and more — with LED diagnostics showing valve health at a glance.
Built-in ESS Sabre DACs
The CSA hybrid models feature ESS ES9018 DACs in quad-mono configuration — PCM 384 kHz and DSD128 without an external converter.
Handcrafted in Denmark
Founded in 1984, Copland is a small Danish specialist — every amplifier is hand-assembled and individually tested by Ole Møller's team.
Since 1984
The art of amplification.
Ole Møller founded Copland on a paradox: how to scientifically approach a system that must perform as a medium of art. For four decades, his answer has been pragmatism over dogma — valves where they bring dimensionality and life, transistors where they bring power and control, and sometimes both in the same chassis. The CTA 407 delivers 2 × 50 W of high-biased push-pull valve power through three custom toroidal transformers. The CSA 150 pairs a single 6922 triode with 150 W of MOSFET-driven force. Both share the same DNA — the ability to disappear, leaving nothing between you and the music.
