Clear Audio Basic+ Phono Pre-Amplifier

Clear Audio

Behind the multiple award-winning 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.

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