Leben CS300XS Nautilus

Welcome to the world of audio... you can grab for your self something unique not available on the audio market often... Why this XS version of highly recommended CS300 Leben is so unique? It is because was upgraded...not by "John" in his garage but by Nautilus Poland. All upgrades done is the effects of years of pursuit for the best possible sound...and they have done it. This incredible unit is a proof...

The amplifier was upgraded by replacing the capacitors and resistors with top Mundorfs. The capacitors are high-class Silver-Gold Oil. The resistors are also "top shelf" - they contain platinum and palladium. After heating, they have losses of about 10% conductivity.


The connecting wires inside the amplifier were also replaced. They consist of palladium, titanium and copper. The current flow rate in such wires compared to the factory ones is 98 to over 60. The amplifier was resoldered with a special tin containing 40% silver, which significantly improves conductivity and, consequently, signal quality. In my Leben, the RCA inputs were also improved with such tin, as I mentioned above. On the other hand, the potentiometers and regulators were cleaned and filled with a special cleaning and maintenance fluid imported from Japan. The entire amplifier was inspected and measured. So that everything worked according to the designer's assumptions. In total, 4 capacitors and 8 resistors were replaced, as well as the power socket with Oyaide Power Inlet PP with platinum-palladium pins.

AHP fuse has been replaced with Verictum one (!)...

Below you can read about it. For some Google translator might be needed ;-)
