Step up transformer box for Electrostatic headphones (just like all Stax - models etc.) include in the setlist. The name of this model is EST. It can be powered from 8 ohm amplifiers, but particularly also from the OTL output of the RKV 2 + 3 (100 Vpp). The device provides both the required for the operation of the headphone-static voltage of 280 / 580 VDC, and up to 550 Vrms signal voltage. The bandwidth achieved while nearly 100 Khz.

This box is ideal for owners of all kind of STAX electrostatic headphones. The combination of RKV Mark 2 and this box give an impressive authentic sound that was perhaps never previously been achieved so. But how can that be, you might ask ... Well, quite simply. In general, the output transformers do indeed known to the problems.
In the EST box but this is quite different. If one uses preferably the RKV
Of course, the output transformer of the company have Pikatron little stray - inductances / capacitances, but the extremely low impedance output resistance of the RKV prevents its adverse effect on the sound.
For this reason, it is almost a must, this combination - to listen RKV / EST.
The EST does not require a separate supply voltage and gains required for the STAX static high voltage elegantly from the signal. A separate supply voltage is always fed possible cause of interference and should if possible be used.

as a driver with its output voltages of up to 80 Vpp, a sufficient translation of the transformer of ratio 5 In addition, the exchanger is designed as autotransformer - galvanically coupled.
