Koru Phono Preamplifier

The Koru phono preamplifier is presented in the Ross Stevens-inspired curved chassis, with a slight twist. The chassis is actually two-in-one, allowing physical separation of the power supply from the amplification circuitry.

The power supply boasts a virtual battery approach with over 100,000 micro Farads of capacitance and very sophisticated 2 stage regulation. This ensures the lowest impedance and consequently extreme accuracy of power delivery to the amplification stages.

The amplification and equalization use the latest components ensuring accuracy and longevity. Low output moving coil cartridges as well as higher output moving magnet types can be used and there is a full range of user adjustments available on the rear panel.

P100 Phono Preamplifier

This compact little unit packs a powerful punch. Delivering on style as well as acoustic performance, the P100 joins the Plinius range, proving that good things really do come in small packages…

Amplification and equilisation circuitry in the P100 are derived from the Phono stage in its big brother the Hiato, and are comprised of the latest componentry ensuring longevity. Low output MC cartridges as well as higher output MM cartridges can be used and there is the ability to adjust Loading, Gain and Input Capacitance on the rear panel for wide compatibility.
