DS Audio DS-E3 Optical Cartridge With Equaliser

Cartridge

Uses a third-generation optical cartridge mechanism

The DS-E3 uses a third-generation optical cartridge mechanism, the same design as our other products.

The DS-E3 achieves an overwhelmingly low price while inheriting the merits of the third-generation mechanism, such as higher output due to independent LED and PD, improved channel separation, and the use of a beryllium light shielding plate.

Aluminium cantilever with elliptical needle

The cantilever is made of aluminium and the needle tip is a solid elliptical needle. While adopting the third-generation optical cartridge mechanism, the channel separation is set 1db lower to improve mass production efficiency.

Equaliser

New Amplification and Power Supply Circuits

In the DS-E3 equaliser, the amplification circuit has been made symmetrical, and the voltage supplied to the cartridge has been stabilised to achieve a clearer and faster sound.

Miniaturisation is achieved by using an operational amplifier

The DS-E3 equaliser uses an operational amplifier as the amplifying element to minimise the signal path, thereby greatly reducing the number of components and achieving a smaller size. As a result, the DS-E3 equaliser is about 1/3 the size of the DS003 equaliser.

FAQ

What tonearm is compatible DS Audio Cartridges ?

Most tonearm is compatible with DS Audio. Tonearm's ground must be connected. Tonearm with ground not connected or no grounding is not recommended to use with DS Audio. 

Most tonearm will physically mount a DS Audio cartridge, but to get the best performance you need to match the tonearm’s effective mass to the cartridge, and also make sure the arm handles the tracking force, compliance, and the specific wiring / grounding that DS’s optical cartridges need. Contact Groove Audio for more details.

Can i use other phono preamp with DS Audio Cartridges ?

You need to use DS Audio Cartridges with DS Audio Equaliser. You cannot use a conventional MM or MC preamp for DS Audio cartridges.
