Very nice Luxman L-590ax Class A integrated amp that we just received on trade.  This is a 2 owner unit (and thus the 8/10 rating per Audiogons rating rules).  It's in fantastic condition with the original triple shipping boxes, manual, remote control and power cord.

Unit Info --


Pure Class A

Thanks to the always-on nature of the topology and the removal of an
entire type of distortion, allied to sound that excels in a midrange
liquidity, low-level detail, superb dynamics and transparency, its
devotees are more than happy to put up with low efficiency and heat.
What Class A always seems to offer above everything else is a tube-like
sound without the maintenance hassle of tubes.



Input Selector

The L-590Ax, L-550Ax and the L-509u, feature the new high quality
electronic selector switch, which is the heart of the C-1000f pre-amp
(one of Luxman's 80th anniversary commemoration models). The sound
quality deterioration using the new electronic input switch is now
minimal, while channel separation and crosstalk efficiency were raised
substantially in comparison with the L-550A / L-590A. In addition the
illuminated position indicator around the input selector knob, makes it
much easier to view the selected position even from afar.




Volume Control


The integrated amplifiers also benefit from the C1000f in that they use a
variation of the LECUA 1000 volume control. At any single volume
setting only a few resistors are in circuit per channel. The less
devices in the signal path, the purer the sound, the cleaner the music.
At low listening levels, potentiometers have trouble keeping both
channels in balance, so one channel might easily be 3dB louder than the
other. With the volume control made of discrete parts, this is no
longer an issue.



Amplifier

The amplifier section has not been ignored either; noise and distortion
has been kept to a minimum with the introduction of ODNF version 3.0A.
The deep, rich Class A tone is available here is Luxman's hall-mark
sound. More info on ODNF below.



ODNF

Luxman holds many patents for audio engineering, amongst them is the
application of Global Negative Feedback to the output stage, which while
widely used throughout the audio industry, they no longer use
themselves. Luxman nowadays use 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. Conventional
negative feedback systems can have an adverse effect on the music,
introducing phase distortion. "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 is
alleviated, again improving sound quality.



Pure Copper Cabling

Extensive listening was applied to the high purity, oxygen free copper
(OFC) cables which are used to transmit the signal throughout the
amplifier. These cables have a minimal audible signature and minimal
electrical effect on the audio waveform. Linear wide bandwidth frequency
response is achieved by the low measured values of both inductance and
capacitance. The result, the cables do not color the sound, but pass it
through, quickly.



Phono Amplifier

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. The MM input has approx. 35dB of gain. While the MC input
has 55dB of gain (a multiplication of 550x). We recommend MC cartridges
with an output >.25mV. Lower than that you might consider using the
MT-88 moving coil step-up transformer. Click here to be redirected.



Subsonic Filter

A subsonic filter is also easily accessible from the remote control in
order to remove unwanted low frequency noise while you are listening to a
record. When the stylus hits the groove, you might notice the woofers
modulating in and out, even though there is no music playing yet. This
is due to the ultra low frequency information (below the music), this
unnecessary information places a strain on the amplifier and is best
filtered out. A mono switch is also available for both loudspeaker setup
as well as mono record playback. Both the Mono & Subsonic filter
are accessible from the remote control.



Headphone Amplifier

There is also a high quality headphone amplifier, accessible from the
front panel, ideal for late night listening. You can turn off the
speaker output by a simple click of the Speaker Selector. The headphone
outlet sees the same signal as the speaker terminals, there is one
resistor per channel in the signal path to pad down the output.



Two Pairs of Speaker Terminals

Large speaker terminals for driving two individual sets of speakers. At
the turn of the speaker switch, it is possible to change between the two
pairs of speakers easily. In addition, if the A+B function is switched
on; Takasina capacitors are used to parallel the output which permits
full double bi-wiring of a single pair of speakers.



Tone Controls

The 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 challenging. A lot of the 1980's CDs are quite harsh
sounding and the digital glare can be quite fatiguing. Reduce the
treble slightly and while the harsh CD is not going to suddenly sound
like a reference recording, at least it will now be perfectly
listenable. Sit back relax, enjoy the music and forgot about the HiFi.
When you want to bypass the tone controls, just engage the Line Straight
switch, either from the remote control or from the front panel.



Remote Control

RA-17 remote control not only handles Mono, Line Straight (tone controls
defeat), Separate (Home Theater Processor Bypass), Subsonic (rumble
filter for vinyl playback) and even Loudness (mild boost of bass &
treble for low level listening). The RA-17 also controls the main
functions of the Luxman D-05, 06, and 08 CD/SACD players.
