The Audolici I-50 series is the result of 20
years of audio engineering experience.
The idea was born from the unfortunate reality that
the majority of today's valve amplification designs
lack the legendary character of classic valve designs.
Audolici's objective is to restore the typical
character of 60/70's valve designs coupled with
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
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
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
