About the Q4B Linestage

The BEZ Model Q4B is a high-quality tube linestage preamplifier designed and hand-built by Edmund Lam in Hong Kong, likely dating from the late 1990s to early 2000s. It features a pair of 6SN7 tubes for gain in an SRPP configuration, a 5Z4P tube rectifier, and includes tube regulation for enhanced performance. The preamp is constructed with heavy gauge stainless steel, making it very durable and industrial in design. It offers three inputs for expandability, large robust knobs, and high-quality connectors and chokes in the power supply. The power transformer is user-switchable between 115V and 220V. The sound is characterized by a bit of warmth and sparkle, with the ability to tailor the sound signature by selecting different 6SN7 tubes. The unit uses a stepped attenuator volume control and side-mounted inputs, which may affect setup convenience. Overall, it is considered a well-designed, functional, and budget-friendly tube preamplifier with a solid build and quality components.
