The Qualiton 300B is an integrated stereo amplifier with 2 x 25 Watts output power, built around the captivating sound character of 300B power tubes. This amplifier harmoniously blends our classic heritage with modern details: it features refined vacuum tube circuits, which have been enhanced with several additional functionalities. In shaping the overall sound character, the primary goal was to move away from the pronounced coloration often associated with amplifiers utilizing the 300B tube. Instead, this is a smooth, musical and balanced vacuum tube amplifier that excels across the entire audio frequency range.
