DS Audio optical phono cartridges and phono preamplifiers offer exceptional reproduction accuracy using cutting edge technology.

Digital Stream Corporation Headquarters

DS Audio, a division of Japanese company Digital Stream Corporation, entered the world of high performance audio with the introduction of their first phono cartridge and phono preamplifier models in 2015.  Since that time they have successfully launched new models, and those new models have earned increasing praise from the hi-fi press and for users all over the world.

DS Audio’s parent company, Digital Stream Corporation, which is headed by Tetsuji Aoyagi, has a longstanding reputation for innovation and high quality products in the world of high technology.  They have been an innovator and leader in the field of optics for more than 25 years and one of their best known products is the wireless optical computer mouse, which they developed for Microsoft Corporation.  

Although the various series of DS Audio products consist of matching phono cartridges and phono preamplifiers, those products can be mixed and matched to achieve the system balance and the budget constraints of the individual user.  However, DS Audio phono cartridge and phono preamplifiers must be used together since they are not traditional components, but rather use optics for their basis of operation.

Traditional moving magnet and moving coil cartridges belong to the “velocity proportional” method where the output signal depends on how fast a magnet or coil moves within the magnetic field.  At lower frequencies, they move more slowly, so the output signal is very weak.  Conversely, at high frequencies, they move faster, so the output signal becomes disproportionately strong.  A phono preamp requires complex circuitry to compensate and correct velocity proportional output signals in addition to having to manage RIAA equalization.

The DS Audio optical cartridges use an “amplitude proportional” method, where the output signal depends on how much distance the stylus is moved, and is not frequency dependent.  As such, it only requires a very simple, high quality circuit and only needs passive RIAA equalization in a partnering phono preamplifier.  This results in a music reproduction system that is simpler and easier to obtain accurate reproduction with.
