QUALITON 300B Integrated Amplifier

Overview

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 we have enhanced with several additional functionalities. In shaping the overall sound character, our primary goal was to move away from the pronounced coloration often associated with amplifiers utilizing the 300B tube. Instead, we envisioned a smooth, musical and balanced vacuum tube amplifier that excels across the entire audio frequency range.

 

Powered by 300B

The 300B is a directly heated power triode that hardly needs an introduction. Originally developed by Western Electric in the mid-1930s for amplifying audio in movie theaters, it later became a favorite among audiophiles and one of the most successful vacuum tubes in history. Its outstanding sonic properties led us to name our top-of-the-line integrated amplifier after this phenomenal power tube. Its high linearity and low distortion serve as the perfect basis for the amplifier's power block, in which we combine it with our own custom output transformer for excellent low and high frequency behavior. Additionally, we have integrated the newest iteration of our Automatic Bias System for continuous and precise control of the quiescent currents, providing a seamless user experience.

 

Pragmatic Audio Design

At Qualiton, we adhere to a pragmatic approach in tube amplifier design. We believe that a truly exceptional amplifier should:

Be compatible with a wide range of loudspeakers.

Exhibit a Total Harmonic Distortion (THD) of less than 0.5% across the entire power spectrum, from milliwatts to rated power, spanning 20 Hz to 20 kHz.

Maintain a flat THD vs. Frequency plot when measured at a fixed output power.

Deliver fast and controlled transients throughout the audio range, which goes hand in hand with the frequency response being wide and flat.

Operate at low noise levels with an exceptional signal-to-noise ratio.

Combine thoughtful design, robust technical parameters, and exceptional sound quality.

In the preamplifier and driver sections, the 12AX7 and 12AT7 tubes play a crucial role in achieving these goals. Furthermore, their DC-stabilized filament supply and circuits with low offset and stable DC operating points ensure resilience against parameter variations.
