The L-507Z is the first model in Luxman's new generation of Z series integrated amplifiers. It features the company's new LIFES (Luxman Integrated Feedback Engine System) technology, which is an advanced amplifier feedback circuit that has been designed to provide realistic, fresh, and rich musicality. The LIFES circuit is based on Luxman's previous ODNF (Only Distortion Negative Feedback) technology and aims to improve upon it by reducing the number of paralleled elements while still maintaining high-performance levels. This results in less distortion in the amplification stage and more natural sound quality.
The L-507Z has a high power output, with a class AB power output of 110W+110W (8Ω) and 210W+210W (4Ω), which is comparable to a separate power amplifier. This allows it to drive any compatible speaker system with ease and bring out the best in its characteristics. The amplifier also features a large needle VU level meter and a 7-segment LED display, which helps the user monitor the output levels and make precise adjustments.
In terms of design, the L-507Z has a rectangular chassis housing with an ultra-thick front panel that is finished in a high-quality, blasted white color. The top panel is made of precision hairline-finished aluminum, which gives it a luxurious look and provides excellent heat dissipation. The large ventilation slots on the top panel ensure that the amplifier maintains stable operation even during extended use.
In addition to its advanced LIFES technology and high-quality design, the L-507Z also features Luxman's new LECUA1000 88-step, electronically controlled attenuator, which is integrated into the amplifier circuit to minimize degradation of sound quality over the full range of volume control. The amplifier also has a discrete buffer circuitry in the output section of the preamplifier, which allows it to drive the power amplifier with confidence.
In summary, the Luxman L-507Z is a high-end integrated amplifier that aims to provide excellent sound quality and performance. Its innovative LIFES technology, high power output, and luxurious design make it a standout product in its class.
