PureAudio Control Preamplifier

The PureAudio Control Preamplifier is an exercise in minimalism. We have removed as much as possible from the signal path, and used only the highest grade parts where they contact the music. The result is a preamplifier that sounds absolutely superb!

The heart of the product is a high precision 32 step attenuator utilising non-magnetic Vishay-Dale resistors. This attenuator gives fine control over the volume setting, and has essentially no impact on the signal passing through.

Our user interface has been reduced to just a volume control. Input selection is automated, responding intuitively to your needs. Complete flexibility is provided, with the preamplifier easily forming the heart of a purist 2 channel system, or integrating easily into a combined 2-channel / home theatre installation.

The preamplifier is constructed as a complete dual mono design, with entirely separate power supplies, signal paths, and ground systems. The interior is kept free of electronic noise, with no microprocessors, or other noise polluting elements. The result of this is that the signal that emerges at the output terminals is a pure and exact replica of that at the input, with nothing added, and nothing taken away. When partnered with our Reference Monoblock Class A Power Amplifier the two products interconnect and interact seamlessly as a system in response to your needs.

As with all of our products, the chassis design fully supports our musical goals. Constructed from heavy aluminium, stainless steel mesh, and supported optimally on three custom designed feet, the non-resonant, non-magnetic structure presents a beautiful, architectural look.
