Review MASSDROP Thx 789 Linearunit Only

Introducing the Massdrop MDX-19090-1 THX 789 Linear Unit, a high-performance linear amplifier designed for audiophiles seeking an immersive and accurate sound experience. This amplifier unit, manufactured by Dayton Audio under the THX certification, is a standout addition to any home theater or hi-fi system.

The MDX-19090-1 THX 789 Linear Unit is a monoblock design, meaning it is built as a separate amplifier for each channel (left and right). Each channel is rated at a continuous power output of 150 watts into 8 ohms and 300 watts into 4 ohms, ensuring that it can easily drive most speakers under normal listening conditions. The amplifier's ability to deliver consistent power and maintain a stable operating temperature makes it an ideal choice for demanding applications.

This linear amplifier utilizes a THX 789 Class AB design, which combines the advantages of both Class A and Class AB topologies to deliver a balanced and articulate sound. Class A amplifiers are known for their purity and low distortion, whereas Class AB amplifiers offer increased efficiency and power handling. The THX 789 design aims to leverage the strengths of both designs while minimizing their weaknesses.

The MDX-19090-1 THX 789 Linear Unit features a robust MOSFET power supply, which provides stable voltage and current to the amplifier circuitry. This ensures that the amplifier can deliver consistent and accurate power to the speakers, even during complex and dynamic passages in music or movies. Moreover, the amplifier's high current capability allows it to effortlessly drive low-impedance speakers without any noticeable distortion or compression.

The amplifier's input sensitivity is specified at a reasonable 0.775 volts, making it compatible with a wide range of source components, such as CD players, turntables, and AV receivers. The MDX-19090-1 THX 789 Linear Unit also includes a selectable 12dB/octave Butterworth crossover, which allows you to seamlessly integrate subwoofers or passive speakers into your system.

The MDX-19090-1 THX 789 Linear Unit is housed in a heavy-duty aluminum chassis, which not only provides excellent thermal dissipation but also contributes to the amplifier's rugged and elegant appearance. The front panel features a clear indicator LED for each channel, which illuminates when the amplifier is in operation. The amplifier also includes gold-plated binding posts for secure and reliable speaker connections.

In summary, the Massdrop MDX-19090-1 THX 789 Linear Unit is a versatile and powerful linear amplifier that delivers accurate and immersive sound performance. Its THX 789 Class AB design, robust MOSFET power supply, and selectable crossover make it an excellent choice for audiophiles and home theater enthusiasts looking to elevate their listening experience.
