The Luxman M-6000 is a lot of amplifier.
It measures nearly two feet across, weighs well over a hundred pounds and delivers 300 watts per channel. And even with both channels driven simultaneously at full output, each channel has no more than 0.05 percent harmonic and intermodulation distortion at any frequency from 20 Hz to 20,000 Hz into 8 ohms. However, considering its equally substantial price ($2995), the M-6000 is not likely to become the world's largest-selling power amplifier. Or even your next amplifier.
Lux power amplifiers from 75 watts up.
Happily, the M-6000 is only one of four Lux amplifiers (75, 120. 180 and 300 watts) each of which was designed to be the world's finest at its power rating.
Considering the number of fine power amplifiers already on the market, this was no small undertaking.
Lux engineers have long been aware of common deficiencies of high-power amplifiers. For example: difficulties in handling complex signals not disclosed by conventional sine-wave testing: difficulties in driving complex reactive loads (such as presented by many of the new exotic speaker designs) not revealed by conventional testing with load resistors.
Our position: specifications don't tell the whole story.
Lux designers are not only engineers, but audiophiles who carefully listen to their products. They know the many little-appreciated aspects of amplifier design that contribute significantly to sonic qualities apart from the data provided by conventional test techniques and instruments.
For example, sophisticated protection circuits were developed that could detect electronically-subtle differences between normal high-level output signals and abnormal voltage/current conditions.
(Overly-enthusiastic protection circuits can introduce audible and unpredictable distortions when operating with certain loudspeaker loads.) In some models, each stage-class-B output and Class-A drive-has independent power-supply sections to prevent intermodulation effects. And fully independent power supplies for each channel maintain the full wattage potential of each channel under continuous large-signal drive conditions. The extremely rugged power supplies and massive heat sinks make a major contribution to reliability and long-term performance stability of the Lux amplifiers.
Lux differences you can see.
Two large front-panel meters continuously indicate average output levels. The meter-circuit sensitivity can be switched to set the 0-dB output references. On some models, sequential LED displays supplement the meter readings, to indicate instantaneous peak powers. Another LED functions as a--ready" indicator of circuit status.
A precision potentiometer with detents in 1-dB increments from 0 to minus 20 dB sets the input levels with repeatability, affording perfect level tracking between the two channels.
New approach to preamplifiers too.
In preamplifier design, conventional specifications and test techniques were also reexamined along with other recently reevaluated parameters. Among them; phase/time linearity, rise time, slew rates in circuits employing feedback, overload sensitivities, and clipping characteristics-all recognized as contributors to significant-if subtle sonic differences.
For example, one decision was to make the magnetic phono-input circuits virtually overload-proof: thus they will accept up to 450 millivolts at 1,000 Hz without clipping; far beyond the output of any good magnetic cartridge playing any signal on any record. Further, distortion originating in the phono-preamplifier circuits-rarely mentioned in spec sheets--is on the verge of the unmeasurable at 0.006 percent. The rest of the preamplifier

Tuner features; from Dolby to variable AM muting.
Lux tuners also demonstrate close attention to functional and sonic detail.
Model T-310 uses four-gang tuning capacitors and MOS-FET circuitry to provide excellent interference rejection and a state-of-the-art sensitivity of 1.7 microvolts 11-uF. 2.2 microvolts for 50 dB quieting. Special five-pole phase-compensating filters in the IF section provide 1.5 dB capture ratio and exceptional distortion characteristics (0.1 percent in mono, 0..12 percent in stereo.) FM stereo separation exceeds 40 dB in the audibly important mid-range frequencies. Calibrated Dolby circuits (model 310) decode Dolbyized FM broadcasts and Dolbyized tape recordings. Even the AM section received serious attention. For example, variable muting eliminates interstation interference.
Sorry if this has been too heavy.
Much of the above may be heavy going for most readers, even of this magazine. But we know there is a small but significant number of dedicated audiophiles who now own a fine receiver or even a separate amplifier and tuner but who have also been patiently waiting for the level of performance provided by the new Lux components.
Their patience can now be rewarded at a select number of similarly dedicated audio dealers.
