TRIODE TRZ-300W

The Triode TRZ-300W is a single-ended tube integrated amplifier operating in pure class A, born from the renowned Japanese attention to craftsmanship and sound quality. With a power output of 20 watts per channel at 8 ohms, it delivers all the warmth and rich tonal character typical of 300B tubes, offering an intense and immersive listening experience. The cabinet is made from top-quality materials and finished with great care, featuring an elegant design that makes it a pleasure not only for the ears but also for the eyes. On the rear panel, there are numerous connections, including four gold-plated RCA line inputs, a dedicated phono input for moving magnet cartridges, and the option to use the amplifier as a power amplifier only via a MAIN IN input, along with a Tape-Out output that enhances its versatility.

The TRZ-300W also stands out for its remote control, crafted from machined aluminum with a modern and robust design, allowing convenient management of volume, input selection, and mute function, making the user experience more practical and refined. Although it uses a fixed bias system, the amplifier offers tools on the top panel to easily monitor and adjust the bias and to balance hum, ensuring simple and precise maintenance during tube replacement.

From a technical standpoint, the power supply section features a large toroidal transformer and Schottky barrier diodes made of silicon carbide (SiC), which provide efficient, stable power with excellent dynamic response, improving fluidity and speaker control. The amplifier employs four Psvane WE300B tubes in the output stage, paired with two pairs of 12AX7 and 12AU7 tubes in the input stages, configured in a PSE (parallel single-end) circuit to deliver pure class A power.

The TRZ-300W is a worthy successor to the VP300BD model, improving its performance and offering greater sonic refinement, ideal for enthusiasts of pure and natural tube sound who appreciate its excellent musicality and refined construction.
