RPX35 Class A - DualMono - Single Ended
The refined and exclusive design is only the visible part of the quality, the best must be heard!
Clean design, very solid accurate construction, very long tests and tuning, to give the audiophile world the greatest pleasure! Amplification works always Class A, with a very high damping factor, that gives the RPX-35 the highest control over any kind of transducer. The RPX35 is a very fast solid state amplifier with a great punch, but with a natural and warm sound due to the accurate study of harmonics pattern, and the use of single ended topology.
Polished shining stainless steel bodyshell, thick aluminum silver anodized faceplate, handmade chromed knob, laser engraving, Style and quality.
Dual mono topology, showing a mixture of pure audiophile, clean, and optimized electronics, to deliver the finest sound available. The electronic design precisely calculated and very clean implemented, ensures the shortest signal path, a must in the real audiophile world. The power supply using capacitance multiplier, delivers the pure DC for that pure sound and black background.
High transparency, real life soundstage, deep and full basses and refined mid-highs, with astonishing dynamics, and absolutely crystal clear sound. Versatility is a must in modern life, so in order to enjoy this great amplifier better, two headphone output jacks were provided, one for hi-sensitivity with lower power (L), and the other for low-sensitivity cans, with higher output (H). The outputs can be used together at same time.
Pre-out available as standard on all RPX35. The "pre out" (a set of RCA connection on the rear panel) is controlled by the volume knob and makes it possible to use the RPX35 as an outstanding preamplifier working with power amplifiers or powered speakers.
To ensure a top notch performance, the components are selected from best brands available to us, followed by an accurate and solid construction and very strict tests in high qualified labs. All the components (including cables and wires) are certified to fully match the severe European Community safety regulations.
Product Facts
In January 2007 RPX33 has been introduced
In springtime 2007 RPX33 was sold as a combo with Ultrasone Edition 9 by Ultrasone America
RPX 33 has been reviewed by Stereophile June 2007
In January 2008 RPX33-ev08 was introduced
RPX33-EV08 has been listed in the 2008-2009-2010 Stereophile recommended components guide
In March 2011 RPX33 has been improved with new encapsulated transformers, became a new look, and name change in RPX35
What changed from RPX33 to RPX35
Power supply now uses encapsulated transformers in order to prevent any possible EMI emission
The enclosure is now made of amagnetic polished stainless steel, this makes the amplifier structure more solid and immune to hum
The amplifier is 3 cm less deeper, it can be installed on small tables or shelves much easier
The circuitry has not changed so the sound of the RPX33 is still there, in a new shining more attractive box!
This product is made in Europe in respect of CE regulations by professionals and qualified laboratories under supervision of RudiStor R&D LABS
