Clearaudio Azimuth Optimiser

Clearaudio Azimuth Optimiser. Comes with Clearaudio test record, manual, and wallwart PSU that works with a range of 100 - 240 volts. Functions perfectly but does have a couple of marks on the lefthand side which I've tried to show in the photos.   
My asking price includes shipping world wide and please search the web for more info.
This is a precision measurement unit that 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.  
The unit also has a high quality phonostage built in, so that the sonic effect of adjustment may be compared against the scientific measurement. Plus it has 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.
