This is the ORION vacuum tube hybrid amplifier (SMC-280BT). The listing includes the main unit, remote control, speakers (2), instruction manual, speaker cables, and FM antenna. ＜Product Description＞ A vacuum tube is installed in the preamplifier section, which affects sound quality. By capturing the unique noise of vacuum tubes, which is the enemy of music signals, it produces a rich sound quality that cannot be reproduced by digital alone. The audio signal generated by the vacuum tube preamplifier is amplified by a digital power amplifier, dynamically driving the speakers. It is equipped with a 20W + 20W total 40W amplifier, which is easy to use in a general household. Full-range speakers are deliberately used to bring out the characteristics of the vacuum tube. For comfortable music enjoyment without being overly concerned, we have focused on sound image localization and vocal texture.
