Luxman introduced the L-550A and L-590A in 2005, since then they have celebrated our 80th anniversary with commemorative components that have reaffirmed Luxman’s status at the pinnacle of high-end audio. With the introduction of the updated Luxman 550Ax and 590Ax, the gorgeous texture and three-dimensional performance of the original Class A amplifiers has been retained and further refined. For example, the Luxman 550Ax and 590 feature a new electronic selector switch, adopted from the input section of the C-1000f control amplifier. The internal circuitry includes customized OFC wiring and a high-speed Schottky barrier diode for the power source section; improvements that have notably enhanced the sound quality for greater musical enjoyment.
Chassis bases have superb vibration absorption in order to suppress noise levels. The power transformer, electrolytic capacitors and amplifier output stage are laid out so as not to interfere with each other. To reduce interference further, the block construction isolates each section using shielding panels, and extensive internal filtering to reject magnetic flux interference. In short, the Luxman 550Ax takes audio to a new level.
Luxman’s patented ODNF circuitry has redefined the relationship between music signals and noise. ODNF does not use phase compensation or NFB loops in the music signal path, instead it accurately isolates distortion components to cancel them. Luxman holds many patents for audio engineering, including Global Negative Feedback to the output stage (1955) which, while widely used throughout the audio industry, is no longer used by Luxman. Instead, Luxman utilizes a distortion reduction circuit called “Only Distortion Negative Feedback” (ODNF). This system works by isolating noise & distortion at the output from the music signal and sparingly applying negative feedback to suppress them. The circuit features such an ultra-wide range, ultra- high slew rate and ultra low distortion that it does not use phase compensation for the music signal amplifying circuits.” This new technology also ensures that need for a DC servo circuit circuit is alleviated, again improving sound quality.
The Luxman 590Ax includes two sets of large speaker terminals. At the flip of the speaker switch, it is possible to change between the two sets of speakers. In addition, if the A+B function is used; Takasina capacitors are utilized to allow bi-wiring a single pair of speakers. The speaker outputs may also be muted if desired, as in the case of headphone listening.
Tone controls might seem like an anachronism in this day and age of minimalism, but they can be remarkably effective in bring to life a less than perfect music collection. We all have music gems in our collection that are sonically challenged. A lot of the early CD’s are quite harsh sounding and the digital glare can be quite fatiguing. Reduce the treble slightly; your old favorite music will now be eminently listenable. Sit back relax, enjoy the music. When you want to bypass the tone controls, just engage the Line Straight switch.
Enjoy the ability to play or record your LP collection with the built-in phono stage which accommodates both Moving Magnet and Moving Coil cartridges. A high quality headphone amplifier is included and accessible from the front panel. The headphone output is taken from the speaker output, assuring you of the highest fidelity. A subsonic filter is easily accessible on the front panel to remove unwanted low frequency noise while enjoying a record. A mono switch is also available for both loudspeaker setup and mono record playback.
Easy to use, intelligently laid-out, aluminum remote control; all of the primary functions of the Luxman L-550Ax and L-590Ax, including power on / off can be controlled from the comfort of your listening chair. Besides the electronic volume control, there is also a mute feature. The display meters’ back light can also be turned on / off from the remote control.
The Luxman L-590A Class A Integrated Amplifier combines the traits of vintage Class A equipment along with the latest technology to create a world class integrated amplifier at an affordable price. If you are in the market for a new integrated amplifier, put the Luxman L-500A on your short list. Contact us to arrange for an audition today.
