Tom Evans MicroGroove & MicroGroove+
Following the success of "The Groove" phono stage, it was realized that the price of the original placed this technology out of the reach of some listeners. Rather than compromise on components "The MicroGroove" utilises the same basic circuit topology as its predecessor, i.e. a low noise Class A front end device providing gain, feeding a passive equalisation circuit, followed by a phase error correction circuit with an active DC servo around the correction stage to roll off subsonics and DC offset. To reduce costs, both channels are built onto a single board powered by a single power supply. In "The MicroGroove+", the proprietary discreet Lithos regulator is included to greatly improve the quality, transient response time, and noise figures of the voltage rails supplying the whole board. This brings the benefit of CD-like dynamic range, neutrality, resolution and the ability to clearly define the edges of notes and the spaces between. This provides the listener with a far more accurate and dimensional representation of the original performance.
