RPX-100 comes from a new and sophisticated electronic design. It is the addition of superior performance of the pure solid state Class-A design to the warm musicality so loved by tube enthusiasts

RPX-100 is a pure Class A amplifier, working either in balanced or unbalanced input and output, or in any combination of them. The high current output, the absolute zero negative feedback (local or global) and the great capability of controlling the transducers make RPX-100 an astonishing transparent and dynamic amp.

The double dualmono topology ensures the deepest and more natural head-stage.

What to expect from its sound?

Well the feeling of sound deepness, along with the sound coming with incredible dynamics form a pure black background, in a correct linear reproduction, is the best way to describe the performance of the RPX-100, sure it will surpass the most exquisite demands of the more refined audiophiles.

The great flexibility of this amplifier, capable to drive any headphone from few ohms to thousands, in both balanced and unbalanced mode, always without any quality compromise (when working in unbalanced it is a pure single ended amplifier) is increased by the three way input selector, and the preamplifier output.

It is well known that an headphone amplifier is always a good preamp for power units driving speakers, so a top unit like the RPX-100 become an unbeatable preamplifier. In order to give the user the possibility of fully enjoying this feature the RPX-100 have a double pre-out connection (balance and unbalanced) this added to the three way input selector can make it a central piece in a Hi end systems.

The RPX-100 comes after a log hours of work at the RudiStor R&D labs, it use only discrete components, and since RPX-100 use four independent high-current power amplifiers based on bipolar transistors, it is a pure quad mono amplifier. The amplification units work, two per channel on positive and negative phase of the sound signal. A real no compromise solution
