Luxman L-560 (1986)

Many Class 'A' amps use so-called quasi-Class 'A' configuration regardless of their remarks and namings, which are totally different from our genuine Class 'A'. With the bias current fixed, the signals are amplified without switching, thus producing none of crossover and notch distortions associated with the quasi-Class 'A' amps, assuring absolute stability even into low-impedance loads. And unprecedented generous 50W per channel taken out at the cost of lavish structure equalling that for 250W/ch in quasi-Class 'A' or Class 'AB' operation, reproduces all the subtleties of music even at a low listening level to say nothing of an overwhelming dynamism at a high volume.

Large Smoothing Capacitors

The giant power supply section features toroidal transformer and newly developed pure-focus capacitors, which eliminates leakage of flux, to reproduce the subline sound image with steadfast core and an explosive volume feeling at the bas range.

9-Point Turnover Frequencies for Tone Controls

Emphasis is placed on the frequencies rather than the amount of variation, enabling you to select 9 different turnover frequencies in either of the bass and treble ranges. Lux's acclaimed NFb type controls assure smooth variation curve without spoiling sonic quality.

Ultimate Pure Sound

The key portions of the chassis are copper-plated to remove the magnetic distortion that triggers modulation of music signals, and the copper-foiled styrol capacitors wrapped by butane rubber totally banish mechanical resonance that is converted into electrical distortion, thus providing the ultimate purity in sonic quality

Purification of Amp Circuitry

For thorough expression of the core of music , highly purified sonic quality is required, and only when the amp circuit is simplified such purest sonic quality is yielded. The ideal, simplest "Single-Stage" Amp is brought about with elimination of the entire one amplification stage in the form of to

, which has throughly solved all the problems associated with the multi-stage amplification such as adverse effect of mains noise, deterioration of slew rate caused by stagger treble compensation, etc.

Puryfication of Erth Circuitry

The earth circuit provides "reference" to all the operations of amp, and the immobile grounding point is the basic condition of a good amp. First we banished the mains-referenced amp circuit and employed all the clean, earth-referenced amp circuits. Then the input and output loops of curret were reviewe at each amp circuit to provide an utter independence to each of them.  And our exclusive Star circuit with discrete placement of erth-line from the reference point to each circuit totally removes harmful inter-earth-line or inter-stage distortion.
