The Audolici I-50 series is the result of 20 years of audio engineering experience.

Audolici's objective is to restore the typical character of 60/70's valve designs coupled with modern innovations.

Audolici manages to achieve the legendary vintage sound, yet faster, more detailed and extended in frequency response than vintage Luxman or Dynaco designs.

This result was achieved through the incorporation of Valeriy's own ideas on the amplification process.

Most classic valve amplifiers use strong current “heavy” output valves : 12BH, 6884, ECC85, ECC88 and similar. This is almost a trademark in all valve designs of the last 40 years.

These current heavy valves make it very difficult to achieve speed because they are heavy for the power supply.

We use a different philosophy: to relieve the behavior of the output valves by matching them with other types of driver valves, 6N1P and 6N2P Russian New Old Stock military standard valves.

We match these driver valves with Russian New Old Stock 6L6 valves for the “Jazz” model, and also with Russian modern valves, EL34's from “Electro-Harmonix” for the “Blues” model and 6550 from Svetlana for the “Swing”.

With these combinations, we are making it easy for the power supply, increasing it's integration time for peak signal.

This is a small part of the secret to achieve transient response speed. We also use modern technology in the production of our own transformers.

Our transformer cores achieve a more effective induction for the same size/weight, thus delivering extended bass response and dynamics than conventional transformers. They also present a very low parasitic induction factor.

Many amplifiers lose dynamics, soundstage, frequency response because of primitive switching. This is why we keep our designs  simple (two inputs on the I-50 integrated).  We also use a proprietary special relay switching circuit for the purpose: Audolici I-50 selector.

Furthermore, we use high quality components like carbon resistors, polypropylene capacitors, ALPS potentiometers and our own networking cabling, all contributing to Audolici's highly detailed and uncompressed sound.
