Overview

Luxman's L-509X integrated amplifier has a slew of high level technology and design principals, but they're easy to forget when the music starts to play and the true analogue VU-meters start to dance. 

Seriously though, Luxman has spared no expense designing and building the 509X, in their own words a "refinement of separates in a single unit". The amplifier section is based on a 3-stage Darlington circuit where only the distorted components of the audio signal from the output of the amplification circuit are fed back.

The unit can be used as a power amplifier bypassing the internal preamp section, or as a preamplifier bypassing the internal power amp output. 

Vinyl enthusiasts are also covered with a single phono input switchable from MM to MC via the front panel. 

Not one, but two XLR inputs avoid you having to pick which input device to run balanced. 

Crack-resistant peel coat PCBs for the amplifier boards feature the non-angled, direct wiring pattern, known as the original LUXMAN Beeline construction.

The power supply features a 600 VA EI-core-type power transformer and independent left and right channel large capacity blocking capacitors with 10,000μFx4 per channel.
