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.

      With a little luck the ATC SIA2-150  review will be completed this weekend.  It has been on hold for several weeks now as things popped up that robbed me of time or energy but it seems at least half of this weekend will be free so I'm going to step on the gas and see if I can get this one finished and written up.  I know there's at least one SNA'er waiting on it.

      It isn't a large amp, reasonably weighty though at 20kgs, but it can pump some serious power.  As demonstrated at Terry's place it was one of the few amps that we tried on those VA Concert Grand speakers of his that took control and made the speakers perform.  This places it in the same category as the Sansui 907 NRA, 907 Limited, ME-240, and Zeus Integrated.  And that is some pretty decent company to be in.
      The ATC suffers a little in my home system in that it doesn't impress as much as it did at Terry's place.  I think this is one of those amps that reacts well to being asked to work harder so it will step up on lower impedance speakers.  Since my Lenehans are fairly benign in impedance I believe the ATC is coasting a little.  Still a very good amp but not quite as "Wow inducing" as it was on those VAs of Terry's.
      Details to follow once my washing machine has finished it's job and quietened down a bit.
      There is more info on the ATC SIA2-150 on page 5 of the thread Terry and I started, link below.  Some rather nice pics too.

      Item: PrimaLuna Dialogue Premium Integrated Tube Amplifier - ExDemo
      Location: Douglas HiFi - Perth
      Price: $3680
      Item Condition: Ex-Demo  (around 50-100 hours of use) - Excellent Condition with all Original Packaging and FULL WARRANTY
      Reason for selling: Recently Discontinued Model
      Payment Method:  Cash, Paypal, Visa, Mastercard
      Here's a chance to grab a sale price on our ex-showroom model of the PrimaLuna Dialogue Premium integrated Amp.  
      PrimaLuna have made quite a name for themselves by making modern tube amplifiers that have the magical warmth and depth of tubes with modern world technologies applied to make them relatively fuss free without impacting sound.
      The PrimaLuna Dialogue Premium Integrated is a beautiful looking and sounding amp... and we really enjoy the lovely, detailed full and open sound that this amp brings to nearly any speaker we have run off it in-store. This Amp has a fantastic amount of drive and saturation to the sound that helps bring a fantastic, real in-your-room sound that normally is only hinted at until hitting some pretty expensive equipment.
      Featuring (5x) RCA stereo inputs, a Sub RCA output (and also with a Home Theatre Bypass mode) the PrimaLuna Premium Integrated is made easy to integrate into a two channel or Surround system.
      The PrimaLuna range is all expertly designed and manufactured to a level that seems impossible for their price.... more importantly the sound has the sublime sound of tubes coupled to a neutral, airy top end without the roll off of many others.
      Don't buy good.  Buy perfect.  Iconic.  State of the art.  Something that will still be relevant ten years from now and that is built to last a lifetime. 
      So how do you know if it's simply good or world-class?  
      a Stereophile Class A rating.  Class A is defined as  "Best attainable sound for a component of it's kind, almost without practical considerations" with practical considerations meaning at any price. 
      The Absolute Sound's Dick Olsher is possibly the most experienced and technically adept writer on staff when it comes to tube amplification. He declared "It is my current benchmark in integrated tube amplifiers."  resulting in a 2014 Editor's Choice Award.
