Audio MUsic Neuer Preis -Audio Music RT3

I am selling the Audio Music RT3 silver edition top HighEnd preamplifier. The silver version utilizes pure silver conductors with a square cross-section and 24-karat gold strands in all critical signal paths and the umbilical cord connecting to the power supply.
No expense was spared in the pursuit of absolute musical reproduction; it is a stunning feat of design and engineering. The multi-function controls, featuring 33-step volume adjustment, are meticulously manufactured in-house to ensure maximum quality—the result of years of research and development. These potentiometers interface with multiple transformer windings—also produced in-house—to provide the first stage of amplification, functioning as an exceptionally impressive passive "RS Transformer" preamplifier. This stage then feeds the uncompromising tube amplification section, powered by a massive power supply unit weighing approximately 25 kg. The monstrous transformers boast a bandwidth extending from 15 Hz to 122 kHz.
The preamplifier operates in Pure Class A, single-ended mode, employing two 6H30 tubes as drivers and two 6922 tubes for amplification.
It features a dual-mono design, with completely separate transformers, power supplies, and voltage regulation stages to eliminate noise and crosstalk. It employs a large number of high-quality U-Cap copper-foil capacitors, carefully selected for their natural, analytical sound.
The design of the new tube preamplifier is quite unique.
A remarkable level of performance has been achieved through a completely new audio and power supply circuit design. This new audio circuit is an all-tube, Class A, zero-feedback design utilizing four long-life tubes (two 6H30s as drivers and two 6922s as gain stages); furthermore, it features a truly balanced circuit design in both the input and output stages, supported by two transformers for volume control.

The power supply is divided into two separate sections: a main power transformer for the audio circuit, and MOSFETs used for both voltage stabilization and constant-current supply. This enhances reliability and ensures the most linear tube amplification possible.
Thanks to its superb build quality, carefully selected audiophile-grade components, versatility, and ability to musically transform any system, the AM R-T3 not only delivers remarkable clarity and detail—presenting instrumental tones and textures in an unmatched, stunningly realistic manner—but also offers excellent value and high reliability.
