Luxman Int Amps - ownership thoughts...

Recommended Posts



This is actually a reply to another SN member's review of his Luxman 509X Int Amp.


After replying, I thought it would be nice to share it with other SN members. Just my thoughts on the three Luxman amps I have owned over the last few years.


I have been lucky enough in the last few years to have own the 550AX Class A as my first Luxman Int Amp, then due to a house move, needed more power, I got the 590AXII Class A, now living most of my time in Thailand, I am enjoying the 509X Class AB. I have also listened to the 507uX Class AB extensively.


My gear from the 550AX to 590AXII and 509X haven't changed - Macbook > JRiver or Roon App > Chord Hugo TT DAC (Cable = Audioquest Diamond USB from Mac to Hugo TT) > every Luxman Amp (Cables = MIT SL8 RCA interconnects) > Spendor D7 SPEAKERS (Cables MIT SL 9). 


Quick rating of each amp:

1. 550AX Class A 20 watts pc. (Build - 8) - (Look - 10 - if you like the Retro style) - (Power/Drive - 8 - ONLY if you have a small room, efficient speakers & don't listen loud) - (Clarity/Details - 7) - (Quietness - 7) - (Soul/Emotion - 8

2. 590AXII Class A 30 watts pc. (Build - 9) - (Look - 10 - if you like the Retro style) - (Power/Drive - 8 - ONLY if you have a small/medium room & efficient speakers) - (Clarity/Details - 8) - (Quietness - 8) - (Soul/Emotion - 9

3. 509X Class AB 120 watts pc. (Build - 9.5) - (Look - 10 - if you like the Retro style) - (Power/Drive - 9.5 - Most room sizes and most speakers) - (Clarity/Details - 9.5) - (Quietness - 9.5) - (Soul/Emotion - 8)


Quick summary of each amp:

1. 550AX Class A 20 watts pc. Fantastic Class A Int Amp. Low power, which leads to other limitations. Only buy if you don't have enough money to buy the 590AXII for more Power and Soul/Emotion.  

2. 590AXII Class A 30 watts pc. Great Class A Int Amp. Still low power for larger rooms. BUT simply amazing tones that ooze Soul and Emotion especially in vocals and acoustic music. Luxman Class A Masterpiece.

3. 509X Class AB 120 watts pc. Stunning Class AB Int Amp. Tons of power and punch. So quiet, so much details, so clean, etc. Only negative against the 590AXII - doesn't have that Luxman Class A Soul and Emotion. Against Class AB Amp in this price range, the 509X has very few to no rivals. 


My "Ultimate" Amp:

*A Luxman because of the build quality, features and acceptable price. Compared to nearest & equal rival, Accuphase, Luxmans are a bargain.

*A Luxman Class A Int Amp for the tone, soul and emotions that they produce.

*A Luxman Class A 60 watts pc Int Amp!! - maybe impossible and imagine the heat!


Play more music!


To the 2 SN members who bought my 550AX and 590AXII, hope you are enjoying them.

Loved my 507UX, only moved it on as I needed more oomph for power hungry, low sensitivity speakers.


I suspect one day I will buy another one if I can find somewhere to hide it. As @Razuu says, the build quality and value are superb - and the VU meters are mesmerising!

Love my 550AX MKI, large, open-plan living, middle-of-the-road efficiency speakers, love my volume high to loud, and this thing is effortless. I wouldn't necessarily say this amp is only suitable for small rooms, far from it, but certainly always consider speaker efficiency before choosing an amp!

Have owned my 507u for about 3 years now.  Have put many amps up against it and nothing comes close at that price point. Love the phono stage also. I’ve tried to move it on, but just can’t.  Matched with the Spendor D9’s and clays GroB dac, its a match made in heaven

I have owned a couple of Luxman integrateds, though admittedly not in the same class as the above. I do love the retro looks/quality of the newer range. I also have a soft spot for the brand, perhaps in part because it has been able to rise from the ashes of mass-market mediocrity when the company was tied with Alpine.

The L1 was an early one. Can't speak much for its sound after all this time bit it oozes retro (in a different way).

The LV-105 Brid may not have been the last word in accuracy but it had an alluring, smooth sound that was enough to supplant a Sansui AU-517 at the time.

No knock on Luxman Amps whatsoever, but I find the OP's Rating of 550AX Power/Drive puzzling. 8? Only if you have a Small Room, Efficient Speakers & Don't Listen Loud. How can it possibly get an 8?

Hi. Great to hear from proud Luxman owners. A common theme of great built and great sound.


Hi @initforthemusic , thanks for your comment. My rating of 8 for the 550AX is if you have a small room, efficient speakers and don't want to rock the house. When I moved, I went from 4 X 6 room with standard ceiling to 6 x 8 with 3m ceiling with open space on two sides, it just didn't fill the room. Most things were lost but when I got the 590AXII, the Luxman Class A sound was back.  


When I got to Thailand, it was a very difficult decision to go for the 509X instead of the 590AXII. The 509 got the nod because it runs so much cooler than the 590 and in the heat of Thailand that's very important. BUT I still very much miss the emotion that the 590AXII generates.

Realise that Razuu. But if you have say a Medium Room, Medium Efficiency Speakers and like to Listen Loud! (As I do) then it would be impossible to give a 8 Rating for Power/Drive Overall.

Hi @betty boop. your comment about Luxman tubes. In my search to find the Luxman Class A sound missing from my 509X, I have research and talked to a few "experts" about pairing a tube Pre Amp with my 509X power amp section. The 509X is designed to be used as a power amp.


The general consensus is that the pre amp determines the sound signature more than a power amp. So I am seriously thinking of getting the Luxman C-38u Tube pre amp to use with my 509X.






Staying with Luxman should not hurt, amazing "retro" look and hopefully, give me a warmer more sound to compliment the 509X as an Int Amp.


Comments and advice would be great.

      Item: Denon PMA-880R Class A Integrated Amplifier
      Location: Sydney - Epping
      Price: $300 
      Item Condition: Excellent
      Reason for selling: Accumulated too much hifi gear and about to move to a new house
      Payment Method: Pickup - Cash, COD Only
      Extra Info: This Denon PMA-880R Optical Class A Integrated Amplifier complete with RC-156 remote control and Operating Instructions is in mint condition. This amplifier was made in Japan in 1993.  Amps made by Denon in this era were considered to be the best amps that Denon ever made. These amps hardly ever come up for sale.

      I have owned this amplifier from new and it has been very well looked after. The amplifier and remote control still look brand new and are unmarked. It's whole life has been in a cabinet behind a glass door, which is why it still looks brand new.

      This Class A integrated amplifier has a very clean, detailed and powerful output that is impressive for both analogue and digital sources. There are no crackles or hums present and it performs just as well as the day I purchased it.

      The PMA-880R has a solid power supply that uses a shielded toroidal transformer, and a pair of large 12,000uF capacitors for voltage smoothing and a very substantial heat sink. It features a source direct switch for tone controls bypass and optical connection between amplifier stages for detailed sound. Speakers can be connected via A, B, A B front switching. The speaker binding posts accommodate bare wires or banana plugs. The power rating is 2 x 75W RMS at 8 ohms or 2 x 120W at 4 ohms. The Denon PMA-880R uses an Optical class A circuit design for optimum sound quality. Source Direct can be used to bypass tone controls. The Denon PMA-880R accommodates both MM moving magnet and MC moving coil Phono options via front switching.

      The Denon PMA-880R has the following RCA inputs: Phono, CD, Tuner, Aux, DAT/Tape-1, DAT/Tape-2. The amp also has a Record Out Selector a headphone jack, and a loudness button.

      The specifications are as follows:

      Power output: 75 watts per channel into 8Ω (stereo)
      Frequency response: 20Hz to 20kHz
      Total harmonic distortion: 0.02%
      Input sensitivity: 0.2mV (MC), 2.5mV (MM), 150mV (line)
      Signal to noise ratio: 76dB (MC), 94dB (MM), 110dB (line)
      Output: 150mV (line)
      Dimensions: 434 x 160 x 353mm
      Weight: 8.2kg
      Accessories: RC-156 remote control

      Item: Luxman L-509U Integrated Amplifier
      Location: Melbourne
      Price: 5800
      Item Condition: as new
      Reason for selling: need money  
      Payment Method: Pickup - Cash, Paypal, COD Only
      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.

      Item: Luxman 505u Integrated Amp
      Location: Adelaide, SA
      Price: 2500
      Item Condition: Excellent, mint condition
      Reason for selling: Purchased a Devialet 220
      Payment Method: Pickup - Cash, Paypal, COD Only.
      Extra Info:
      Two things to note:
      - The remote is dodgy with its Volume control; over the years I have either changed volume manually or use an external DAC as preamp.
      - I imported the 505u direct from Japan so it was assembled for the Japanese market and set to 100volt mains electricity. Therefore it comes with a Kashimura TI-20 step-up transformer (photos attached). There has never been any issue playing it here in Adelaide.
      The Luxman has been in daily use since July 2010. It has always worked well and given me great listening pleasure.
      A User Manual and the original Brochure are attached. 
      The 505u has a phono input with both MM & MC selections.
      It can be used as a pre-amp only or power amp only.
      The 505u weighs 21kg with dimensions: 467(W)x179(H)x437(D) mm. 
      The transformer weighs 4.5kg and its dimensions are 170x135x100mm.
      I will post both items if there is no buyer in Adelaide for pickup - postage costs would have to be checked and agreed to. 
      I still have the original box available for transportation.
