The Luxman L-505z is an analog integrated amplifier that delivers an impressive 100 watts per channel into 8 Ohms, a nod to the company’s centenary, celebrating its inception in 1925. Crafted with a unique parallel push-pull configuration featuring bipolar transistors, this powerhouse can provide up to 150 watts for 4 Ohm speakers. It includes dual sets of binding posts and defeatable tone controls embedded on the front, along with a remote-controlled loudness feature for those late-night listening sessions.
Visually striking, the L-505z boasts backlit analogue VU meters that transport users back to the vibrant 80s, accompanied by sturdy source selectors and volume knobs that feel satisfyingly tactile. While it doesn’t feature modern amenities like a DAC or streaming capabilities, it offers five line-level inputs, allowing connections to devices like the Grimm MU2 and WiiM Ultra, while maintaining a fixed phono stage suitable for both MM and MC cartridges.
Unboxing the Luxman reveals its substantial weight of 22.5kg, attributed to its robust transformer and power supplies. Unlike many transformer-based amplifiers that hum due to DC mains, the L-505z remains silent, thanks to its EI transformer design. This Class A/B amplifier is engineered with Luxman’s innovative LIFES feedback technology, which aims for natural sound quality by minimising signal feedback, allowing for an audio experience akin to non-feedback systems.
Further enhancing its performance, the amplifier features the high-clarity LECUA volume control, which ensures minimal variation in audio quality and operates smoothly across 88 levels of adjustment. This is complemented by a traditional rotary knob for tactile enjoyment, even though a third-party pre-amplifier can be connected directly to the “MAIN” inputs, which somewhat undermines the integrated design’s purpose.
After months in the making, my review video will delve into side-by-side comparisons with two budget-friendly amplifiers, examining whether spending more yields superior results. It will also scrutinise the internal phono stage’s efficacy against pricier alternatives, as well as evaluating the headphone amplifier’s output options. Expect music selections from renowned publications like NME, Pitchfork, and Rolling Stone to feature prominently in the tests.
The Luxman L-505z is an all-analogue integrated amplifier, celebrating 100 years of Luxman’s legacy with 100 watts per channel into 8 Ohms. It features a solid design with both aesthetic and functional elements, such as backlit VU meters and LECUA volume control. The amplifier lacks digital features, focusing instead on high-quality sound reproduction via its innovative LIFES feedback engine. A review comparing it with less expensive amplifiers is underway to assess its value.
In summary, the Luxman L-505z integrated amplifier is a tribute to a century of audio excellence, combining robust design with impressive performance. Its unique features, like the LIFES feedback engine and LECUA volume control, set it apart in the realm of high-fidelity audio. While it lacks modern digital enhancements, it prioritises sound quality and tactile engagement, making it a compelling choice for audiophiles seeking a powerful amplifier for their analogue listening needs.
