Clearaudio Azimuth Optimizer with integrated Phono Preamplifier
The Azimuth Optimizer is a precision measurement unit that for the first time makes it possible to exactly align the azimuth of the cartridge diamond (stylus) position. The stylus azimuth (the vertical position of the cartridge's diamond when viewed from the front) is the main influence on channel balance, frequency response and stereo separation of a stereo phono cartridge. Visual adjustment of azimuth is not accurate enough to ensure perfect stylus alignment. Exact azimuth can only be determined when using a precision measuring instrument such as the Clearaudio Azimuth Optimizer.
Furthermore a High-End phonostage is built in, so that the sonic effect of adjustment may be compared against the scientific measurement.
An integrated headphone amplifier makes mobile use of the Azimuth Optimizer possible. Any headphones with an impedance of between 100 ohms and 600 ohms can be used.
