DS Audio’s E1 entry level optical cartridge, achieves a performance level well beyond expectation and price range. The sonic qualities and resolution far exceed what one normally associates with an elliptical stylus and aluminum cantilever. That's because it features the technological advances found in all DS optical cartridges. In terms of background noise level, transient speed, and tonal accuracy, the DS E1 is obviously ahead of conventional transducers at a similar or much higher price bracket.
