Know before you buy
The 300B tubes are renowned for their warm, rich, and liquid midrange. This Single-Ended Class-A design prioritizes harmonic texture and musicality, making it an excellent choice for listeners who value vocal clarity and a natural, intimate soundstage.
Yes, the TRV-A300XR features a built-in MM (Moving Magnet) phono stage. You can connect your turntable directly to the dedicated MM input without needing an external phono preamplifier.
The integrated headphone amplifier is designed to provide high-quality output through the 6.3mm jack. While it performs exceptionally well with most standard audiophile headphones, it is best suited for models that do not require extreme power to reach optimal volume levels.
The amplifier delivers 8 watts per channel. Because of this lower power output, it is best paired with high-sensitivity speakers—typically those rated at 90dB or higher—to ensure sufficient volume and dynamic headroom.
No, the TRV-A300XR utilizes a fixed bias design. This simplifies the maintenance process, as you do not need to manually calibrate the bias when installing new tubes.
The unit includes a dedicated remote control that allows you to adjust the volume and switch between the three line-level inputs and the phono input from your listening position.
