However, in the case of optical cartridges, it is only necessary to move a light shading plate with a thickness of only 100 microns, so the moving mass is very low.\u003cbr\u003e\u003cbr\u003e\n \nThis is an additional advantage of optical cartridge technology\u003cbr\u003e\u003cbr\u003e\n\n・What is the detection principle of the optical cartridge?\u003cbr\u003e\n\nThe optical cartridge detects movement of the needle using infrared LED, light shielding plate and two PD (photo cells).\nThe operating principle is simple, the shading plate vibrates in front of the LED, and the PD (photo cells) behind it detects the change in brightness.\u003cbr\u003e\u003cbr\u003e\n\n\nWhen the groove of the record vibrates (oblique 45 degrees), the vibration is transmitted from the tip of the needle to the cantilever, and the shading plate also vibrates together.\u003cbr\u003e\u003cbr\u003e\nSince the shading plate vibrates in such a way as to block the light of the front LED, the brightness entering PD (photo cells) changes continuously from bright → dark → bright → dark.\u003cbr\u003e\u003cbr\u003e\n As the photo cells detect changes in brightness created by record groove movement, the output voltage changes accordingly\nThe movement of the shielding plate will be read as 2 separate stereo channels, by 2 independent photo detectors.\n The angular movement of the shielding plate ensures that each photo detector can only pick up information from its corresponding channel. Information from the parallel movement of the opposite channel will not be read, ensuring accurate channel balance and channel separation.\n ※Since the brightness of the photo cell does not change because the motion of the light shielding plate becomes a parallel movement on the side of the reverse PD (photo cells) side, it is possible to detect audio signals of the left and right channels with one light shielding plate.\u003cbr\u003e\u003cbr\u003e\n\n・The reason why you need a dedicated equalizer\u003cbr\u003e\n\n With an optical cartridge, you can not use a phono equalizer for MM \/ MC, you must use a phono equalizer dedicated to the DS Audio optical cartridge.\nThere are two reasons for this\u003cbr\u003e\u003cbr\u003e\n\nVoltage is required in order to power the internal LED inside the cartridge, and this voltage is supplied by the equalizer\u003cbr\u003e\u003cbr\u003e\n\nPower is supplied to the LEDs of the optical cartridge using the tone arm ground (blue and green lines).\nFor that reason, in order to use the optical cartridge, it is essential that the four cables of the tone arm are properly independent.\n(There is no problem with most arms that are currently on the market.)\u003cbr\u003e\u003cbr\u003e\n\nThe standard RIAA equalization curve required for MM\/MC is completely different from equalization required for optical cartridges.\u003cbr\u003e\u003cbr\u003e\n\n\nBecause the output of an MM \/ MC cartridge is proportional to its speed, the output increases as the speed rises (= higher frequency). However, the optical cartridge has an amplitude proportional output that outputs flat from the low frequency to the high frequency (same as the old crystal type and capacitor type).\u003cbr\u003e\u003cbr\u003e\n\nSince the optical cartridge is classified as amplitude proportional and is not affected by changes in speed, even on the same record, it has totally different output properties. Much less EQ correction is required for the amplitude proportional output compared to traditional MM \/ MC. Because of this, the RIAA correction circuit of the optical cartridge requires much less manipulation of the signal compared to a speed proportional type MM \/ MC cartridge.\nThe RIAA correction circuit of the optical cartridge becomes an overwhelmingly simple circuit.\nThis is yet another advantage of optical cartridge technology\u003cbr\u003e\u003cbr\u003e\n\nThe amplitude proportional type optical cartridge can output the movement of the groove flat from the low frequency to the high frequency, so the RIAA correction circuit of the optical cartridge becomes an overwhelmingly simple circuit compared to the RIAA correction circuit of the speed proportional type.\nThe RIAA correction circuit of the optical cartridge becomes an overwhelmingly simple circuit.\n This is also big merit of the optical cartridge.\u003cbr\u003e\u003cbr\u003e\n\nThe biggest reason why DS Audio was able to successfully bring the optical cartridge back after 40 years is that technologies have evolved for both the light source and for the light detector.\u003cbr\u003e\u003cbr\u003e\n\nToday the problem of “Heat” is not an issue, because very small and high power LED can be used. Unlike traditional incandescent or fluorescent bulbs, LEDs do not generate heat.\u003cbr\u003e\u003cbr\u003e\n\nAnd since it uses a highly sensitive photodiode with its sensitivity characteristics well matched to the wavelength of the light source, it is possible to achieve a very high output. The optical cartridge has about 40 mV output, which is about 10 to 100 times higher than MM \/ MC cartridges, so high output can be obtained from an extremely low mass system. This is an advantage over MM \/ MC systems which require a very low voltage to pass through the tonearm wires, becoming vulnerable to interference and signal loss. The high output of the DS Audio cartridge is much more robust and less sensitive to interference.\u003cbr\u003e\u003cbr\u003e\n\nMix And Match \u003cbr\u003e\n All DS Audio cartridges are fully compatible with any of the company’s accompanying phono stages\/equalisers, so you can mix and match them, the price breakdown being DS Audio Master 1 cartridge plus phono stage\/equaliser at £19,995, the cartridge at £8,150 and the phono stage\/equaliser £12,695 on its own.\u003cbr\u003e\u003cbr\u003e \n\nSignificant when discussing a system that’s five times the cost of its later sibling are the physical differences. I realise ‘Never mind the quality, feel the width’ is a silly basis for an argument, but the less expensive of the two EQ units weighs 4.7kg, occupies a space of 310x92x235mm (whd) and offers only one output configuration via single-ended RCAs. The Master 1 equaliser box weighs 24kg, its size is 436x161x395mm (whd), and the box is filled with a PSU larger than you might find in a power amplifier. \u003cbr\u003e\u003cbr\u003e\n\nMoreover, it offers three stages of subsonic filtering and both single-ended and balanced outputs for each. Balanced is better in every case – more robust and controlled – but the preferred filtering had to be determined by ear on a speaker-to-speaker basis. \u003cbr\u003e\u003cbr\u003e\n\nTurning The Screw \u003cbr\u003e\n Cartridge vs cartridge and not just equaliser is the other issue to address when comparing the Master 1 to the DS-002. Both share identical tracking forces (ideally 1.7g) and both weigh 8.1g. Construction, however, is where they part ways. The DS-002 employs aluminium for its body, the cantilever is aluminium and stylus has a Shibata profile. The Master 1 uses Super Duralumin for its body, has a sapphire cantilever and a ‘micro-ridge’ stylus. \u003cbr\u003e\u003cbr\u003e\n \n What listeners, when first hearing DS cartridges, find most disorienting is this absolute absence of grunge, hum or other background annoyances. \u003cbr\u003e\u003cbr\u003e\n\nDS Master 1 Technical Specifications\u003cbr\u003e\u003cbr\u003e\n\nCartridge :-\u003cbr\u003e\nCantiler - Saphire\u003cbr\u003e\nNeedle - Microridge needle\u003cbr\u003e\t\t\nBody material - Super Durarumin\u003cbr\u003e\nMaterial of indicator section - Natural crystal\u003cbr\u003e\u003cbr\u003e\n\nEqualizer:- \u003cbr\u003e\nSize - W43.6cm x H16.1cm x D 39.5cm \u003cbr\u003e\nWeight - 24 Kg \u003cbr\u003e\nOutput - RCA x 3, SLR x 3\u003cbr\u003e\nElectrolytic capacitor - 120000uF x 12\u003cbr\u003e\nElectric Circuit - Discrete board\u003cbr\u003e\nProduction method - All the resistance of the signal path and the legs of the resistance are hand tangled and then soldered.

In practice\nthen, its 8.1g bodyweight is offset by a low-ish 15\/20cu dynamic\ncompliance, conferring a low ~9Hz subsonic resonance in\nmedium-to-high effective mass tonearms.\u003cbr\u003e\u003cbr\u003e\n\nOutput is a high 1.28V via the equaliser (re. 1kHz\/5cm\/\nsec) – more than sufficient for standard preamp line inputs –\nwhile the ‘eq’ itself yields DS Audio’s customary bass boost that\nbegins below 100Hz and reaches +4.0dB\/20Hz.\u003cbr\u003e\u003cbr\u003e\n\nOnce again big, reflex-loaded speakers are best avoided! The\nmid\/presence response of the DS-W2 is slightly more uniform\nthan either the Master 1 or DS-002 and while the 13kHz treble\npeak is less exaggerated it’s still going to add some pizzaz at\n+6.5dB. This ‘loudness contour’ shows excellent symmetry\nbetween lateral and vertical cuts, promising a very uniform\ncolour across the soundstage. As does the uniform trend of THD\nversus frequency which shows any very high frequency\ndistortion tamed by the pick-up’s post-15kHz treble roll-off. \u003cbr\u003e\u003cbr\u003e\n\nThe DS Audio DS-W2 has its own 26-pound Preamp\/Equalizer (with the W2 cartridge and the equalizer). With it, you get an optical cartridge with a Boron cantilever and a micro-ridge stylus that has a minimum curvature radius. What you don’t get is a cartridge body made of what they call “Ultra” duralumin. Instead, the body is made of aluminum.\u003cbr\u003e\u003cbr\u003e\n\nWith the introduction of the DS-W2, DS Audio once again has three optical cartridges and three Preamp\/Equalizers that all work with one another. This makes it possible to move up in the line in steps, or to find the combination that is right for your ears and your pocketbook. A little birdie tells me that there will most likely be a trade-in path to help owners move up the line.\u003cbr\u003ev\n\nThe biggest visual change from the DS-W1 to the DS-W2 is the Preamp\/Equalizer. To start with, the DS-W2’s Preamp\/Equalizer is about three times the size and weight of the DS-W1’s. This makes it closer in size to the Master1’s Preamp\/Equalizer than to the DS-002 Preamp\/Equalizer. The DS-W2 has two sets of single-ended RCA outputs and two sets of balanced XLR outputs. Output 1 is the “DS Standard” single cut-off with 6db\/octave at 30Hz while output 2 is “RIAA Standard” double cut-off with 6db\/octave 50.5Hz and 6db\/octave at 30Hz. It does not have the third output 3 of the Master1, which is a triple cut-off with 6db\/octave 50.5Hz, 6db\/octave at 30Hz and 12db\/octave at 25Hz. \n\u003cbr\u003e\u003cbr\u003e\nAll cartridges need to be set up correctly to sound their best, and that seems obvious. The point should be made that some phono cartridges are more particular than others about how they are set up. For example, phono cartridges with a conical stylus are not as fussy about set up. When it comes to a cartridge with a micro-ridge stylus, proper setup is critical. In a displacement reading cartridge, the set up of the azimuth and anti-skating is particularly important. One other thing to know about a displacement reading cartridge with a micro-ridge stylus is that it is even more important to set everything up precisely and to keep the stylus clean.\u003cbr\u003e\u003cbr\u003e\n\nThe DS Audio W-2 is all about fidelity and great harmonics played with rich and beautiful tonal color. It offers a little more natural and realistic warmth than the other two cartridges without giving up speed or detail to the DS-002 and only a little to the Master1.\u003cbr\u003e\u003cbr\u003e\n\nTechnical Specifications:- DSW2\u003cbr\u003e\u003cbr\u003e\n\nCartridge :-\u003cbr\u003e\nCantiler - Boron\u003cbr\u003e\nNeedle - Microridge needle\u003cbr\u003e\t\t\nBody material - Aluminium\u003cbr\u003e\nMaterial of indicator section - Natural crystal\u003cbr\u003e\u003cbr\u003e\n\nEqualizer:- \u003cbr\u003e\nSize - W43cm x H10.7cm x D 38.4cm \u003cbr\u003e\nWeight - 12 Kg \u003cbr\u003e\nOutput - RCA x 2, SLR x 2\u003cbr\u003e\nElectrolytic capacitor - 56,000uF x 12\u003cbr\u003e\nElectric Circuit - Discrete board\u003cbr\u003e\nProduction method - All the resistance of the signal path and the legs of the resistance are hand tangled and then soldered.

Firstly, the HS-001 features both an upper and a lower vertical pin structure, instead of the more common single vertical pin on the top side of the connector. The result of this is equalised pressure on the electrical contacts and an even application of force across the connection to the tonearm.\u003cbr\u003e\u003cbr\u003e\n\n\nAdditionally, the whole contact surface is then further anchored by a domed headshell washer, custom-developed by DS Audio.

Two common sources of the friction that creates static build-up are the stylus drag that occurs during record playback as well as simply removing records from their jacket and sleeve.  By emitting both positive and negative ions in a controlled fashion from its dual outlets, the ION-001 ionizer unit effectively neutralizes and removes static electricity from the record surface.  The unique \"fan less\" design allows for silent operation for continuous use while playing records.  Additionally, the ION-001 performs charge removal for Compact Discs.\u003cbr\u003e\u003cbr\u003e \n\nNote: The degree of electyrostatic charge may vary depending factors including stylus tip shape, vinyl record material, temperature and humidity etc. \u003cbr\u003e\u003cbr\u003e\n\nThe ION-001 is a very high-power device, equipped with a total of 4 ionizers, 2 each for positive and negative ions.

The third generation of DS Audio’ s optical cartridge features a comprehensively re-designed optical system that provides the following improvements and benefits:\u003cbr\u003e\u003cbr\u003e\n\nThe new DS Audio DS003 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 DS003 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 DS003 cartridge has made it possible to eliminate crosstalk, greatly improving left and right channel separation (in particular the high frequency separation has improved by 10dB in comparison to its DS Audio forebears).\u003cbr\u003e\u003cbr\u003e\n\nThe implementation of independent left and right channel LED’ s allows for the positioning of the optical system to be optimised 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.\u003cbr\u003e\u003cbr\u003e\nAs a result of this, DS have 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.\u003cbr\u003e\u003cbr\u003e\n\nThe DS Audio DS003 cartridge features the combination of aluminum cantilever with a line contact stylus. The cartridge is made by alminum and the body structure has been designed in such a way as to promote maximum rigidity. In addition to these features, the DS003 utilizes internal wiring 1.6 times thicker than used in the second generation cartridges in order to reduce impedance.","brand":"DS Audio","offers":[{"title":"Cartridge \u0026 Equalizer Package","offer_id":57415662698828,"sku":"DSAUDIODS003","price":4162.5,"currency_code":"GBP","in_stock":true},{"title":"Cartridge Only","offer_id":57423963750732,"sku":"DSAUDIODS003CART","price":1915.0,"currency_code":"GBP","in_stock":true},{"title":"Equalizer Only","offer_id":57423964012876,"sku":"DSAUDIODS003EQUALIZER","price":2622.5,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1053\/6891\/2204\/files\/DS-Audio-DS-003.jpg?v=1777556917"},{"product_id":"ds-audio-es-001-eccentricity-detection-stabilizer","title":"DS Audio ES-001 Eccentricity Detection Stabilizer","description":"The overall wow and flutter of the entire system cannot be significantly reduced unless the eccentricity of the record is corrected\nWith an eccentricity width value of 0.34mm, even if there is no inherent wow and flutter (speed error) produced by the turntable in use, it reaches around 0.15% (WTD RMS) on the innermost grooves of the records playing surface. In reality, the average speed error value of even the highest quality turntables is around 0.008%.
