EISA Award voor de Ground Zero GZPA 4SQ versterker.


Ground zero haalt wederom de EISA award voor in car versterker van het jaar binnen, deze keer met de nieuwe Plutonium serie GZPA 4SQ.
Een korte samenvatting van het jury rapport:

Even it may appear to be a well-known 4-channel class A/B amplifier, the Ground Zero GZPA 4SQ proves that´s there´s much more inside audible already after the first listening session.
The key for success is its sound character which is similar to tube amplified units based on the integrated BIAS setting shifting the amplification from regular class A/B towards class A operation.
Each channel has been equipped with two pairs of200-Watt high power MOSFETs.
The power supply with its huge transformers makes sure to offer sufficient energy at any time for the peak power.
Altogether leads to an amplifier bursting with cutting edge technology, top components and engineering – not least thanks to first grade parts like German made low loss MCAP-MKP capacitors, Burr-Brown operation amplifiers or Japanese Nichicon capacitors.
