cor Integrated Amplifier






The cor integrated amplifier offers the ultimate pure analogue experience. It can drive virtually any loudspeaker, delivering reassuring levels of power with refinement and transparency, yet remaining neutral, imparting no character of its own. It faithfully reproduces vivid, dynamic performances with soul: all the magic of music.

At the heart of this design sits a pure analogue Class A/B power amplifier. Combining cutting-edge and innovative technology with classic discrete design, the cor integrated offers astonishing resolution and control, and conveys the emotion desired by all audiophiles. In technical terms, PMC’s advancement of the pioneering
work of Bell Laboratories’ Sidney Darlington ensures that the end-to-end signal paths are kept as short as possible, with minimal junctions, reducing thermal lag distortion. With enormous dual independent power supplies, the cor integrated has ample power in reserve, and is capable of driving virtually any loudspeaker without leaving its own sonic imprint.

As soon as you group precision components together, you introduce the possibility of interaction and signal taint. A key PMC design obsession is colouration, and how to achieve purity by excluding it. All of the signal routing within the cor integrated is electronically balanced to eradicate electromagnetic fields and keep audio
clean and unblemished. To further exclude interference, the motorised controls have their own power source. It is entirely independent of the cor’s toroidal power supply, which is sheathed in a custom-built MuMETAL® housing designed to keep the adjacent components isolated from the effects of high-power mains current.

The cor integrated has five sonically identical inputs, including a balanced connection for pro audio-style equipment. Pre-amplifier outputs on the rear panel allow you to connect additional power amplification for system upgrades. There’s also a direct input, so the power amp section can be connected to a home theatre system and used to drive the main channels in a multi-channel setup, offering amazing musical performance without the need to rework your wiring.

Once you’re in your listening position, why would you ever want to move? The extruded aluminium remote control allows you to make any volume, balance or tonal adjustments you require at the touch of a button. In keeping with the cor philosophy, all changes made via the remote control are still made in the analogue domain — no digital conversions are involved.

For listeners that want the music delivered directly via high-quality headphones, the cor integrated features an audiophile, auto-sensing Class A/B headphone amplifier. Whatever the sensitivity of the connected headphones, the cor’s headphone output has enough drive to make them sing, whilst protecting them from overload and maintaining a musical, neutral and transparent sound. Rest assured, your headphones will never sound so good.

We know one component can make or break a product. That’s why we test, record and measure each one that goes into our designs. But measurements alone are not enough. Our customers don’t tick values off on a list, they listen with their ears — so we do, too. Each premium-quality component has been selected by ear after, in many cases, hundreds of individual listening tests.
