DS Audio Grand Master Extreme Flagship Optical Cartridge

DS Audio's new flagship Grand Master Extreme optical cartridge benefits from a one-piece diamond stylus and cantilever.
DS Audio has improved on its already impressive Grand Master optical phono cartridge by taking the Grand Master's third-generation internal optical sensor systems, external power supply and amplifier and marrying them to a stylus and cantilever carved from a single diamond.
Rather than using the more common method of a stylus bonded to a cantilever, DS Audio's Grand Master Extreme uses a 0.22mm-square one-piece diamond cantilever with an integral Micro Ridge stylus tip housed in an Ultra Duralumin body. The innovative Japanese company states that this design ensures that there can be no loss of precision or detail at the stylus/cantilever junction, as there isn't one, so the stylus can transmit the groove modulation to the optical generator with incredible accuracy.
As with all of DS Audio's third-generation optical cartridges, the 7.7g Grand Master Extreme utilises independent LEDs and photo-detectors for the left and right channels, enabling an output of more than 70mV while elevating left and right channel separation to above 27dB (@ 1kHz). The required tracking force is 2.0g - 2.2g (2.1g recommended).
DS Audio cartridges require a phono stage/equaliser. While the range is fully compatible with any of the company's accompanying phono stages/equalisers, we're told the Extreme best partners with the model created specifically for the Grand Master. Here the equaliser and power supply are two independent units which promise to fully enable the world-leading performance of DS Audio's top-of-range Grand Master and Grand Master Extreme.
The DS Audio Grand Master Extreme optical phono cartridge is now available at £18,995, with the Grand Master equaliser costing £42,200; however, the cartridge and equaliser can be bought together as a bundle saving £6,119.50. Furthermore, owners of the Grand Master cartridge receive a 20% reduction when upgrading to the Grand Master Extreme.

applause awards
Each time StereoNET reviews a product, it is considered for an Applause Award. Winning one marks it out as a design of great quality and distinction – a special product in its class, on the grounds of either performance, value for money, or usually both.
Applause Awards are personally issued by StereoNET’s global Editor-in-Chief, David Price – who has over three decades of experience reviewing hi-fi products at the highest level – after consulting with our senior editorial team. They are not automatically given with all reviews, nor can manufacturers purchase them.
The StereoNET editorial team includes some of the world’s most experienced and respected hi-fi journalists with a vast wealth of knowledge. Some have edited popular English language hi-fi magazines, and others have been senior contributors to famous audio journals stretching back to the late 1970s. And we also employ professional IT and home theatre specialists who work at the cutting edge of today’s technology.
We believe that no other online hi-fi and home cinema resource offers such expert knowledge, so when StereoNET gives an Applause Award, it is a trustworthy hallmark of quality. Receiving such an award is the prerequisite to becoming eligible for our annual Product of the Year awards, awarded only to the finest designs in their respective categories. Buyers of hi-fi, home cinema, and headphones can be sure that a StereoNET Applause Award winner is worthy of your most serious attention.
