Clearaudio Basic + MM/MC Phono Preamplifier

Behind the multiple award-winning Clearaudio Basic +, which outclasses many much more expensive competitors, there are over 30 years of research and experience, along with in-depth knowledge of the effectiveness of unconventional details.

The Clearaudio Basic + provides up to 60 decibels of gain at one kilohertz and automatically adjusts its input to perfectly match the cartridge fitted. With an equalization accuracy of well below 0.2dB this 1.5-kilogram phonostage provides the acoustic pleasure of a very good concert hall.

Basic + Phono Preamplifier comes standard as a two box unit – phonostage and power supply creating an extremely quite combination.

The Clearaudio Basic + phono preamplifier has enough gain to drive the lowest output phono cartridges. The layout of the circuitry is optimized for high channel separation. It features high-quality gold-plated input and output RCA terminals. A single button switches between moving coil and moving magnet functionality. The circuit board is encased in a solid, resonance-free CNC-machined aluminum chassis, providing excellent protection from unwanted vibration and resonance.

Due to its compact size, the signal path lengths are extremely short, which leads to a pure, noise-free musical reproduction. A dedicated power transformer keeps the audio circuits as quiet as possible.

Clearaudio’s optional Accu Plus battery power supply may be added at any time, allowing the Clearaudio Basic + phono preamplifier to run on pure DC power for even greater performance (note: Basic + comes standard as a two box unit – phonostage and power supply as show – the battery power supply is optional). Via the optional Accu + power supply, the basic + is even usable in a very low interference battery mode where no stray electromagnetic interference can spoil the pure musical enjoyment.

“The Basic + is everything a modestly priced phonostage should be.” Editors Choice Awards – The Absolute Sound

“If you are in need of a phono stage that can handle most anything you throw at it, don’t want something overly fussy and want to listen to the music that can be extracted from your vinyl and not listen to the extractor, then seek out the Clearaudio Basic Plus…” Product of the Year – The Absolute Sound
