Extra Info:

I am one only owner. Bought new for over $8000 in 2012

The amp has never been repaired, works very well. No issues, can give a week warranty.

The unit has never been loud more then 9am because I live in a flat and I like my neighbors.

Winner of SoundStage's Reviewer's Choice Award (February 2009)

 "The L-509u was one dead-quiet integrated amp with an ultra-low noise floor, resulting in the blackest of backgrounds from which the music would emerge in solid, focused, three-dimensional images. Additionally, the L-509u was tonally neutral, and did not favor one end of the frequency spectrum over another; instead its sonic signature was geared toward delivering the least-colored, most musically natural performance, regardless of the type of music." "What impressed me most, however, was the L-509u’s control of the bass." "Subterranean? Without a doubt." Click here to be redirected to the SoundStage review.

The L-509u features 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 previous L-550A / L-590A / L-507 /L-509SE. In addition the illuminated position indicator around the input selector knob, makes it much easier to view the selected position even from afar.

The integrated amplifier also benefits from the ALPS volume control used in the CL-88 vacuum tube preamplifier. A massive solid-brass, four gang potentiometer.

The amplifier section has not been ignored either; noise and distortion has been kept to a minimum with the introduction of ODNF version 2.2. The deep, rich, wonderfully textured tone is available here in Luxman’s most powerful integrated amplifier.  No compromises made for sound quality; designed for the musical purist. This is Luxman’s ultimate integrated amplifier. * Equipped with ODNF version 2.2 for minimal noise and distortion. 

* Solid brass, four gang attenuator from the CL-88 tube preamp.

* Electronic input selector, trickle down technology from the flagship C-1000f.

* Relay power source with large storage capacity.

* One pair of RCA inputs with Luxman's eddy current defeating technology,


* Peel Coat PCB with gold plated traces.

* Power Output Display Meter in dB


* Switch to split the preamp from the power amp.

* High quality phono stage.

* Two pairs of balanced inputs.

* Custom parts designed by LUXMAN, even the paint used on the resistors to denote the value has been carefully chosen after many hours of comparitive listening.

The volume control on the L-509u is a solid brass, four gang ALPs potentiometer, its too heavy to be motorised, hence the lack of a remote control, it does however provide a linear attentuation & gain throughout the range, holding both channels perfectly in balance even at low amplitude.  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 sonicly 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 & forgot about the HiFi. When you want to bypass the tone controls, just engage the Line Straight switch.  Printed Circuit Boards normally have a green coat (dye) that can be printed upon, so the manufacturer knows where to place the copper traces and where to insert the resistors & capacitors. LUXMAN's designers don't like the sound of the green dye, so instead they print onto a plastic peel coat and remove it once the traces and mounting holes are in place. Then the copper traces are gold plated to reduce resistance across the circuit. In the photo below you will notice that Peel Coat circuit boards are an off-white color. It’s this fanatical attention to detail that delivers such superior sound quality.  The on board phono stage is not an after thought on any of the Luxman integrated amplifiers, rather a well executed  pre-preamplifer. The MC input has 55dB of gain (thats a multiplication of 550x) and is suitable for medium to high output MC cartridges, approx .7mV. While the MM input has 35dB of gain.  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.  There is a high quality headphone amplifier, accessible from the front panel. The headphone output is taken from the speaker output,, assuring you of the highest fidelity.  LUXMAN did not cut corners in the L-509u; notice lots of custom solid copper parts including screws & fasteners & mounting plates. Not to mention the gold plated peel coat circuit boards. This is one channel complete with heat sink.  Here is a clever device found on the back of every Luxman powered product. You press the button and it will check the phase of the electricity it is receiving. If the AC outlet in the wall is incorrectly wired, meaning the live and neutral are swapped, a red LED will turn on to warn you. You only need to press it once, when you are installing a product to check that everything is in order. Its a simple mistake, that occurs often, and one that can seriously undermine your listening enjoyment.

Luxman is an amazing brand. Unit you hear it you just don’t realise how nice it sounds. I own a vintage Luxman tube amp and just love it and I’m sure these new amps sound even better.

Before to buy it I had done a big research and then pickup 509U because the advanced volume control. It keeps balanced sound at any volume level especially at low level that I needed.

      Price: $550 Item Condition: Lightly used, fair bit of dust from sitting in storage! Shipping Options: Pickup is available,I can ship this item Suburb or Town: Canberra State: Australian Capital Territory Payment Method: Cash, Paypal, EFT Reason for selling: Clean out Further information: Ive had these monitors for years, however when I moved back to Canberra I never really pulled them out and used them. For the money they are fantastic, add a DAC with a volume control and you've got an incredible sounding system for peanuts. I just pulled them out and set them up, and had a good listen, everything is working and they sound brilliant. I was planning to keep these, but honestly they have just been sitting around not being used, the money could be better put to use elsewhere.
      Unfortunately I dont have the boxes anymore as I through them out, but if you really wanted them shipped, I could securely pack and ship via e-go or similar.

      Price: $300 Item Condition: Very good 7.5/10 Shipping Options: Pickup is available,I can ship this item Suburb or Town: Melbourne State: Victoria Payment Method: Pickup - Cash, Paypal, COD Only Reason for selling: Surplus Further information: 
      Up for sale is this rare set of (4) Wally feet. These were purchased as used items from Secher Audio in 2009 for $600.00. Wally feet were designed by a very reclusive guy, Wally Neumann who took the basis of flagship Harmonix tuning feet, and improved them with a constrained layer design comprised of exotic materials including ebony. For the tweak freaks out there, you can turn the feet over to the other side to get a slightly different tone. There is black felt material on one side and green felt material on the other to denote the different sides. I haven't experimented with this feature, but according to George Secher there is a subtle difference.
      These are 'absorbtion' type feet which are designed to absorb vibration through constrained layer technology then release the energy as heat. I had great success using the Wallys under my dac & cd player, as well as under a power conditioner. To read more about the basic design principle of Wally feet, you can read about Harmonix tuning feet on the Combak/Harmonix website. Harmonix are probably best known for providing the isolation for the legendary Reimyo CDP-777 & more recent CDT-777. The equivalent Harmonix feet are the TU-666ZX which were quite a bit more expensive and retailed for over $1200.00USD for a set of 4!
      Unlike most metallic feet, Wally feet add a touch of warmth. I recall when I bought them, they were by far the best isolation feet George had in the store at the time (which included Aurios Pro Max and a few others). I also recall George saying Wally felt his feet sounded better than the Harmonix feet. In gold and black, they look as good as they sound for sure! Wally feet have been out of production for many years and very rarely come up for sale.
      Condition wise, the feet show normal wear for their age incl: a few minor nicks. There is a minor crack in the Ebony wood on one foot that is only noticeable on close inspection & doesn't affect the performance of the foot at all. The outer gold rings are immaculate. Overall, the feet are in very good condition and have been well cared for since purchase.
      A note about shipping:
      I am offering free tracked shipping Australia-wide. I will ship these items via Australia Post with Signature on delivery anywhere in Australia. They will be packed in a suitable size box with ample bubble wrap to ensure a safe journey. Otherwise local pickup is welcome. I will make a 2% donation to the Bushfire Appeal on completion of the sale. Here is your chance to pick up some true collectors items! Any questions, just ask!
