DS Master1 got a Brutus Award by Positive feed back magazine.


Below is a summary of the review.

“I can say that the results from the beginning and over time with the DS Master 1 have been nothing less than absolutely breathtaking”

“Many turntables, tonearms, and cartridges have come and gone over the past two decades. Frankly, I don’t think that I’ve ever heard better LP playback than the DS Audio DS Master 1 hosted by the NVS and the Durand Tosca. For transparency, clarity, detail, and purity of sound…for making grooves sound like master tape…the DS Audio DS Master 1 is top-o’-the-heap here in 2019”

Sapphire cantilever with micro-ridge stylus

The micro-ridge stylus of the DS Master1 features a minimum-curvature radius and is mounted to a sapphire cantilever. The super low mass optical generator, which eliminates the need for magnets and coils as found in conventional phono cartridges, is free of ultra-sonic ringing. These features allow the Master1 to reproduce every element of musical information with stunning nuances and brilliant detail, redefining flagship-level performance.

Tetsuaki Aoyagi (Aki-San, the Head and CEO of DS Audio) discover that after an experience with one of those old Optical Phono Cartridge and even with its inherent weaknesses, he was deeply impressed with its audible performance. Then and there, in his mind, he already conceptualized a modern Optical Phono Cartridge, without the old inherent weaknesses…with ‘LED’ light source to replace the ‘light bulb’. He returned home, in his hand that old Optical Phono Cartridge and in his mind, a proposal to his father, the head of the Digital Stream Corporation.

That story of the first and single model DS001 Optical Phono Cartridge System from a newly established DS Audio (2013) was five years ago. Nowadays, DS Audio has a catalogue of four models of Optical Phono Cartridge Systems (price range of US$2,500 to US$22,000) and other analogue audio related products. In addition, DS Audio’s business have expanded and they started DS Export to represent a number of audio ‘hidden gems’ products from Japan for worldwide distribution.



The Optical Phono Cartridge is similar with any Moving Magnet (MM) or Moving Coil (MC) Phono Cartridge; all of them have a cantilever with a stylus tip to read the music grooves on a vinyl record. However, their difference is at the end of that cantilever of an MM or MC cartridge (whether magnet or a coil). As the stylus (and the cantilever) traverses the music grooves on the vinyl record, their movements generate vibrations against the electro-magnetic force of the opposing magnet inside the cartridge, generating an electrical signal for the phono amplifier or phono stage. Therefore, there is always magnetic resistance applied against the vibrations or movements by the stylus and cantilever of these MM or MC cartridge.

Whereas the Optical Phono Cartridge, at near the end of its cantilever is affixed a miniaturized screen or ‘shielding plate’ to act as a blind or ‘block’ against the light from the LED (light source) towards the two receiving Photo Cells (a miniaturized Solar Panel which convert light to electricity/electrical signal). Here, the same movements by the stylus and cantilever, together with the ‘shielding plate’ will ‘block’ differing amount of light/brightness to be captured by the two Photo Cells (1 x left and 1 x right), thus generate the differing electricity/electrical signal for the accompanying equalizer system. There is no digital conversion involved in the Optical Phono cartridge.

The same movements by the stylus and cantilever of the Optical Phono Cartridge will not suffer similar magnetic resistance as in MM or MC cartridge.

In addition, the MM or MC cartridge requires to move the load of a magnet or a coil and core, whereas the Optical Phono cartridge only require to move a light shielding plate of only 100 microns in thickness and of almost insignificant weight.

Ultimately, the agility and ease of microscopic movements and vibrations of the stylus and cantilever of the Optical Phono cartridge is far freer in comparison, due to its extreme low moving mass, than any current MM or MC cartridge of whatsoever current designs.

測量數據及使用上之考量
Master 1的一些基本數據,已經在去年刊出過的部分,在此就不再重複。比較值得注意的是下圖方波測試的結果(只顯示右聲道),在向上或下的波型變動之後,很快的就平息下來。這代表針桿在唱頭內部有良好的阻尼,不會在共振頻率持續地來回震盪,也間接地顯示,極高頻不至於因缺乏良好震動控制,而在某個頻率產生鈴振(ringing)。

Both the MM / MC cartridge and the optical cartridge read the record groove through the needle, but the usual MM / MC cartridge detects the music signal by vibrating the magnet (or coil) in the magnetic field.

On the other hand, optical cartridges detect music signals by capturing shadow changes (brightness changes) using LEDs and PD (photo cells).

Because MM / MC cartridges generate electricity by cutting off the magnetic field, magnetic resistance always occurs when the magnet (or coil) moves.

However, the optical cartridge detects only the change in brightness (shadow movement), so no magnetic resistance is generated when the vibration system moves.

Since there is no magnetic resistance applied to the vibration system, the tip of the needle can move smoothly.

DS Audio Master1 Optical Cartridge and Master1 Equalizer

REVIEW by Jonathan ValinAug 13th, 2020

How a DS Audio Optical Cartridge and Equalizer Work?
First, to make this clear from the start, an optical cartridge is a completely analog device. There is nothing digital about it. Like mm’s and mc’s, it reads the information stored in record grooves by means of the mechanical vibrations of a stylus. But where mm and mc cartridges produce tiny voltages by transmitting those vibrations to a magnet or a coil, which subsequently vibrates within a magnetic field in sympathy with the stylus, DS audio optical cartridges do not transmit vibrations to relatively massive moving objects situated at the far end of a cantilever. Instead, they generate signals by capturing changes in brightness, using an internal LED as a fixed light source, internal photoelectric diodes (photo cells) as receptors, and a very thin opaque plate (a mere 100 microns thick) mounted directly behind the stylus as the vibrating system. (See the illo on the following page.) Moving up and down and side to side in tandem with the motion of the stylus to which it is attached, this tiny plate intermittently blocks the light from the LED that is hitting the photo receptors for the left and right channels, generating variable voltages in the photoelectric diodes by varying the amount of light and shade they see.



What’s New About the Master1?
DS Audio made some changes in the DS-002 that are carried forward in the Master1. The LED and photo sensors have been moved closer still to the stylus, as has the thin opaque plate that serves as the vibrating system, so the amplitude of vibrations can be transmitted and read with greater precision. The use of a traditional suspension, where the cantilever is held rigidly in place via a tension wire secured by a setscrew, has also been retained, where other things, such as the stylus rod and the stylus itself, have been outright improved. The DS 002’s Shibata stylus has been replaced by a micro- ridge type mounted to a sapphire cantilever. The cartridge body, once aluminum, is now constructed of light, strong, vibration-resistant ultra-duralumin.

How Does It Sound?
Thanks to its transparency, the Master1’s reproduction of detail is uncannily precise and musical. On the Festival Quartet’s recording of the Brahms Piano Quartet No. 3 in C minor [RCA LSC-6068], for instance, it’s almost as if you’re not only hearing the instruments but also looking at the score unfold in front of you, as if it were superimposed in SurCaps; so when at the start of the third movement andante the lovely viola and piano melody descends by thirds, you hear the interval unmistakably (same, for another example, with the quarter-note durations of the notes in the trio section of the second movement scherzo). In other words, the Master One’s reproduction of pitch and attack is extremely accurate.

Conclusion
The Master1 cartridge and Master1 EQ are simply outstanding products, setting new benchmarks for vinyl playback in several areas (mechanical silence, neutral midband voicing, and midrange-to-low-bass realism). Even where they aren’t setting standards, they are now competitive with the finest coils and magnets. Perhaps the best part of all is DS Audio products still have room to grow: in trackability, in soundstaging, in upper midrange and treble flatness, in overall warmth. Remember, the optical cartridge with internal LED and photo sensors is a relatively new thing. That the folks at DS Audio are taking the perfection of this idea seriously is shown by the remarkable sonic progress they’ve made from the W1 Night Rider to the DS-002 to the Master1. I know this much: If I were in the market for a new phono cartridge and I had the money, the Master1 system would be at the very top of my short list of must-hears. Go listen for yourself, and discover not just a new cartridge but a new phonographic paradigm
