The Plinius Koru phono stage is presented in the same Ross Stevens inspired curved chassis as other Plinius models, with the twist that it\'s internally split into two, allowing physical separation of the power supply from the amplification circuitry. The power supply has received very detailed attention and 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 equilisation circuitry is specific to the new Koru and uses 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. Both single ended (RCA) and balanced output (XLR) signals are catered for and with passive high frequency and active low frequency equilisation the Koru will maintain stability and finesse under the most demanding conditions. Musically it is more revealing and will move you closer to the event than before. Details and images seem to float and the depth and ambient retrieval is a revelation. Available in Black or Silver.
