Supreme 300B Integrated Amplifier 18 + 18 Watts RMS Pure Class A, hand made perfection and beauty.
The Supreme 300B arises as a reply to our desire to create a new, no-compromise circuit using the well known direct heating triode 300B. The circuit presents, for each channel, two power tubes working in a particular Class A configuration in order to achieve great power and an improved damping factor. The power supply stage, as for the entire amplifier, is arranged in a dual mono configuration and uses a pi-inductive – capacitive filtering, designed to reach an optimal leveling and the best possible sonic results. The rectification of anodic voltage is achieved by two 5U4 and a DC regulated voltage is used for all heaters supply. The power stage presents, for each channel, two 300B, a particular configuration that supports the output power of 18 Watts per channel. The circuit, with automatic biasing and with zero feedback reaches a spectacular sound quality, thanks also to the high quality of the silver-plated copper Litz custom hand wound output transformer. The driver stage is composed, for each channel, by an E83CC and a 5687. The E83CC’s function is to magnify the level of the signal coming from the 5 line inputs. The 5687 takes on the function of driving the power tubes accurately. In order to achieve this, we have introduced an interstage transformer on each 5687. Thanks to our expertise and experience, we have discovered that this method of driving power tubes is much better and presents a bold ability to reproduce the tri-dimensionality of the soundstage. The sound reproduction achieved with the Supreme 300B integrated amplifier satisfies the most demanding audiophiles.
