“The Grand Master is so truly supreme in resolution, transparency, spatial recreation, neutrality and any other parameter I can name that it’s impossible for me not say what I usually try to avoid:
‘This may be the best cartridge I’ve ever heard.’” Ken Kessler Hi Fi News 2021

Description

DS Audio Grand Master Cartridge & Equaliser

The Grand Master Cartridge is a completely new design. The Third Generation of DS Audio’s optical cartridge features a comprehensively re-designed optical system that provides the following improvements and benefits.

DS Audio have further developed the optical cartridge system by implementing independent LED’ s and photo-detectors (PD’ s) for the left and right channels. The result is that the cartridge output voltage is dramatically increased from 40mV to 70mV (a 75% increase) and channel separation is greatly improved.

The new Grand Master optical cartridge system has been optimized, by implementing an independent LED and photo-detector arrangement for the left and right channels. As a result the cartridge output voltage has greatly increased from 40mV to 70mV. Despite this dramatic increase in output, the excellent signal to noise ratio that DS Audio optical cartridges are renowned for has not been compromised. In fact, quite the opposite is true. The Grand Master cartridge offers a greatly improved S/N ratio when compared to its stable mates, resulting in an even lower noise floor and far greater musical clarity.In addition to this, the new independent design of the Grand Master cartridge has made it possible to eliminate crosstalk, greatly improving left and right channel separation (in particular the high frequency separation has improved by10dB in comparison to its DS Audio forebears.)

Over 50% weight reduction in our new reshaped, solid beryllium shading plate

The implementation of independent left and right channel LED’ s allows for the positioning of the optical system to be optimized as well as necessitating the use of a new shading plate that has been significantly reduced in size compared to our earlier designs.In addition to this reduction in size, the material used to produce the shading plate has changed from aluminium (as used in the second generation cartridges) to 99.9% pure beryllium.

As a result of this, we succeeded in reducing the weight of the shading plate by more than 50%, from 1.56mg to 0.74 mg. This is less than 1/10th of the mass when compared to the core and coil system found in a typical MC (moving coil) cartridge and further improves one of the key advantages of DS Audio’ s optical cartridge technology, which is an incredibly low effective mass.

Featuring a diamond cantilever, rigid construction design and improved internal wiring.

A first for DS Audio, the Grand Master cartridge features the combination of a diamond cantilever with a microridge stylus. The cartridge body structure has been designed in such a way as to promote maximum rigidity. In addition to these features, the Grand Master utilizes internal wiring 1.6 times thicker than used in the second generation cartridges in order to reduce impedance.

    We will use the most appropriate carrier for your order, anything lost in transit will be replaced in a timely manner, all orders are sent using recognised postal carriers and couriers.

    On heavy and bulky items the charges can be quite high so please enquire via e-mail or telephone us for an exact cost to avoid mis-understandings.

    Delivery times are based on current workloads, we try to dispatch in stock orders within 3 days of receipt, if your order is urgent please add a note in the order comments box. Occasionally we may run out of stock of an item or if it is built to order (power supply’s, mains leads etc) it could take slightly longer to dispatch.

    Shipping charges start at £1.95 for small items like plugs and connectors, heavy items cost more and need to be sent insured delivery so please consider that when the cost appears in your basket.

    Any questions about postage or delivery please tel. 01484 540561 or send us an e-mail

    All items on the site (except those made to order) can be returned under the consumer contracts regulations within 30 days. Please contact us prior to returning so we can discuss your requirements. If the item has been specially ordered (not specially made) we reserve the right to charge a nominal re-stocking fee. We expect any goods returned to be in new condition complete with original packaging otherwise we reserve the right to refuse a refund. Items classed as “tailor made” cannot be returned under the regulations although Brook Audio may accept the return under certain circumstances.

    Please note if you order goods from Brook Audio and live outside the EU you may have to pay import duty/taxes on your purchase. We have no control over this charge and we do not pre-pay the charges for you. We do not declare a lower value to avoid customs charges so PLEASE DO NOT ASK US TO DO THIS.

    We get asked 100’s of times every week for tracking numbers, these are usually a waste of time as they only tell you that the goods are progressing through the carriers system. Usually for items sent overseas the country you live in will determine how quickly your goods arrive, as an example the Spanish postal service is very very slow, the Russian customs clearance can take weeks as well as Brazil.
