DS Audio is a newly formed audio business group in Digital Stream Corporation (“DSC”) this year.
DSC has been known as the provider of industrial laser optics systems in the optical disc market, in Medial testing systems, and for various laser optical instruments.

DS Audio DS-E1 (DSE1)
|
|
In common with all DS Audio’s proprietary
pick-ups, the DS-E1 employs a derivative of the
technology it developed along with Microsoft
some 20 years ago – the optical computer mouse.
Inside the DS-E1’s alloy body a miniature LED is positioned between the stylus
tip and cantilever fulcrum, its light output modulated by an extremely fine
optical plate, just 100μm thick, fixed to the rear of the cantilever. This shines on
a photocell which generates an electrical current, directly mirroring the passage
of the stylus through the analogue groove.

DS Audio DS-002 (DS002)
|
|
The new DS Audio DS 002 optical phono cartridge combines the latest optical cartridge technology with a more budget-friendly price point. Featuring an aluminum cantilever and classic Shibata stylus, the DS 002’s optical screen is positioned closer to the stylus–a breakthrough in phono cartridge design allowing for more accurate reading of the information within the record groove.
Like the more expensive DS Audio cartridges, the DS 002 cartridge body is machined from aluminum and echoes their distinctive design for best optical performance. The DS 002 features an aluminum cantilever and classic Shibata stylus to accurately reproduce the music recorded on the vinyl record album. The DS 002’s optical screen is placed near the stylus tip, together with a newly developed wire-suspension system to hold the cantilever. The new position of the optical screen is a breakthrough in phono cartridge design, providing a much more accurate reading of the groove information and contributing to clearer sound reproduction.

DS Audio DS-W2 (DSW2)
|
|
While the latter DS-W1 cleared the maximum 80μm groove pitch and the
most severe +18dB modulation (315Hz lateral cut, re. 11.2μm)
at<1% THD, the Master 1, DS-002 and DS-W2 are secure to
+15dB but mistrack at the maximum +18dB groove modulation.
This is a perfectly acceptable trade-off for the reduced dynamic
compliance of the DS-W2’s ‘tie-wire’ suspension. In practice
then, its 8.1g bodyweight is offset by a low-ish 15/20cu dynamic
compliance, conferring a low ~9Hz subsonic resonance in
medium-to-high effective mass tonearms.

DS Audio DS Master 1

First, to explain the difference of detection principle between the optical cartridge and MM / MC cartridge.
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.

DS Audio ES-001 Eccentricity Detection Stabilizer
|
|
The overall wow and flutter of the entire system cannot be significantly reduced unless the eccentricity of the record is corrected
With 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%. These factors combined can result in an overall wow and flutter value 20 times worse than that of the turntable in isolation.

DS Audio DS-003 (DS003)
|
|
The DS Audio DS003 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:
The 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).

DS Audio ION-001 (ION001) Vinyl Ionizer
|
|
Vinyl Ionizer ION-001
Generates positive and negative ions to neutralize and remove the static charge from vinyl records.
Vinyl records have a surface static electricity charge created by friction. 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.

DS Audio HS-001 Headshell
|
|
Japanese engineering at its very best now turned from optical cartridge systems to the headshell itself
The new HS-001 solid headshell is designed to provide a superior fitting for all phono cartridges, not merely DS Audio’s own high-performance optical models.
The headshell’s design hones in on the point of contact with the tonearm and improves upon the conventional approach in two keys ways. 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.

DS Audio ST-50 (ST50) Stylus Cleaner
|
|
DS Audio's ST-50 Stylus Cleaner features a special Urethane resin cleaning gel housed inside a high quality, nickel plated aluminum case.
DS Audio first accessory, the ST-50 Stylus Cleaner utilizes a specially designed Urethane gel, the same gel used in the industrial-grade clean room conditions. The Urethane prevents dust from entering the clean room by absorbing it in the micro level. The high-quality aluminum material used for the casing features a nickel plated surface. Real leather is used on the base of the casing for no damage to your platter.
