Moving Magnet & Moving coil phono preamplifier

Make the most of any turntable, including the most high-end audiophile models with this Moving Magnet & Moving Coil phono preamplifier


There's something uniquely pleasurable about listening to vinyl, something that digital media can't reproduce in quite the same way. However most hi-fi amplifiers won't let you plug in a turntable directly. You need to connect via a phono stage (also known as a phono preamp) to make the very small signal from the turntable powerful enough for your main amp to work with. But it's very easy to add noise at this stage, which is why we've designed the CP2 using premium components chosen for exceptional accuracy, amplifying the signal without distorting it.

The CP2 works with all turntables, whichever type of cartridge they use. Like the CP1 it works with popular Moving Magnet cartridges. But it also works with Moving Coil cartridges found in the highest-end audiophile turntables offering even more accuracy and detail than Moving Magnet. Even if your amplifier does have a built-in phono stage, it's well worth bypassing it using the CP2 to deliver much greater depth and detail.

Audio circuitry has been refined with multiple transistors wired in parallel ensuring the lowest possible distortion and noise. A copper shield provides further protection to this extremely sensitive part of the circuitry, limiting the noise that can be injected into the signal. This is especially important with a Moving Coil cartridge because its signal is even quieter and more delicate than Moving Magnet, so it needs even more amplification.

  • Phono pre-amplifier with moving magnet (MM) and moving coil (MC) input stages
  • Balance control for fine correction of cartridge imbalance
  • Discrete transistors for the all-important input stages instead of the more common integrated circuits
  • Eco-friendly <1W Standby power consumption
  • Single-ended ‘Class A’ gain stage with audiophile passive RIAA equalisation
  • Available in brushed black and silver finishes
  • Multi-parallel capacitors to achieve exceptional RIAA accuracy of only 0.3dB up to 50kHz
  • Selectable subsonic filter to eliminate very low frequency ‘rumble’, caused by vinyl imperfections


High-spec multi-parallel capacitors achieve exceptional RIAA accuracy - the industry standard for reproducing vinyl recordings. A highly accurate, subsonic filter also removes the common problem of unwanted low-frequencies that are inaudible but can damage subwoofers.
