for those owning sansui amps, or other components, and you want to know the month and year your unit/s was/were produced, just check the serial numbers at the back.
these units usually have 9-digit serial numbers. the third digit is the year of manufacture and the fourth and fifth digits represent the month. (the model series generally determines the decade produced.) e.g. Sansui AU-D607x produced in '80s with serial number 064117923. based on 3rd, 4th and 5th digits that unit was manufactured in November 1984.
anyway, Sansui remains the most popular hifi brand in AudioKarma.

AU-D607F came out in 1980 to 1981 in Japan. equivalent model in the US (as well as those sold here in the '80s) was AU-D7S. it is rated 80wpc @ 8 ohms. the original price in the US market was $480, current re-sale value in the US is less than $100.
top of the line in the F series is 907F (120wpc), then 707F (95wpc). here in Davao, 607F is sold by traders (in retail shops - good condition) at prices ranging from P3K to P4K. i think those interested should start haggling at below P3K.

okay na yan, basta vintage luxman maganda. but it should be priced lower than Sansui AU-D607 (as per original pricing in Japan). here's a link for its specs. use Altavista Babelfish to translate: www11.plala.or.jp/se_ke5583/LUXMAN/amp/l-400.html

i had an L-430 once, had a hard time letting it go. yours looks exactly like mine except for some minor face lifts, like a light at the volume pot, the 430 is if i recall it right more powerful as well.

i just recovered old photos of my Sansui alpha 907 and 907F that i thought were lost when my files got mysteriously erased at Image Shack two years ago. i added new shots of au-x11 and decided to post nudies of these three top of the line amps for documentation, hoping these could be of use to Sansui amp owners and would-be owners. by the way, i noticed that the DC offset and bias trimpots could be seen clearly on the photos. the DC offset variable resistors are the easiest way to tune up a normal SS amp to prevent overheating, protect the tweeters as well as maintain ideal stereo balance. on the 907F photos, the DC offset trimpots are the round plastic blue buttons. be careful if you're adjusting, it could trigger the power protection circuit or damage the transistors, better to consult first with JojoD. there are available front panel photos of these amps on the web but except for the au-x11, others don't have photos of these amps uncovered. so, here we go: my top choice, the alpha 907 was TOTL in 1987 and was rated at 160wpc. curiously, my unit has different weight and power consumption specs compared with the k-nisi alpha 907 unit. this has 400watts consumption (370 in k-nisi) and weighed 30 kgs. (28 kgs. in k-nisi). the au-x11 was top of the line in 1983 and was made as a true audiophile amp. it is big 21X16X7.5, weighs 28 kgs. and rated at 160wpc. the 907F was the most powerful integrated amp outside of the au-x1 in 1981. it is rated 120wpc and was released in the US and international markets as AU-D11.

Pogi sir. I like the copper chassis of the AU-x11 amp.

thanks, sir Narayan. i'm sure you're also happy with your new Sansui alpha acquisition. the au-x11 was a revision of the au-x1, which Sansui loyalists said is probably the best sounding integrated amp ever built. it was also described worldwide as Sansui's "sunugin" amp. the company's engineers reportedly pushed au-x1's design to the limit and that resulted in unstable bias and eventually bad case of oscillation. the faceplate of au-x11 is same as au-x1 but with wood side panels. au-x1: au-x11:

i would love to have one of that. Luxman hybrids were a favorite among Tsinoys in Manila back in mid '80s. however, those hybrids didn't register well with Jap audiophiles, probably because it was made after the Alpine takeover and years after Luxman's design engineer Tim Paravicini had left (transferred to Musical Fidelity to design the original MF-A1 amp.) still, i would buy a Luxman hybrid if i see one here in Davao.

not familiar with that CDP. all i know is that Luxman's line back in the '80s - amps, tape decks, turntables - is a notch higher compared with those of other brands. i would also look for a hybrid CDP if i have a hybrid amp.

Nice Luxmen!!!
My brod just compared a Luxman m120a against a Sony 5650, a Pioneer SA9500.
luxman m120a 120wpc Pioneer sa9500 80wpc Sony VFET ta5650 70wpc speakers used kef reference 104ab source china made dvdplayer comparison done without tone controls and with loudness off comparisons done with volume at 9oclock and at 12oclock results:
power output as expected goes to luxman. the other are about the same. bass goes to luxman as well. deeper and more controlled. the other two sound the same. Difference is night and day. treble seems the same for all three midrange goes to ta5650. Can be noticed with tracks with predominant vocals and instruments like trumpets and saxophones. ta5650 is "real sounding" while the other two are sometimes harsh and "processed" during loud passages. The point is maganda talaga ang output ng Luxman.

Sir Foo,
naunahan mo lang ako dyan sa M-120 na 'yan! just checked its auction price at eBay a few days ago, still running at over $500 good condition, a lot higher compared with popular tube amps in the US. all it needs is a good mid to upscale pair of speakers to show what it can do.
i think the AK guys were also offering their excess M-120s at no less than $600 per unit. M-120 was built in the '70s, malamang nagdaan pa kay Paravicini yan before it was released commercially.

Sir Sandawa,
I know its not an apple to apple comparison and that the requirements of the User is paramount but how would you compare the following:
Sansui Aud907x decade (integrated amp TOTL) Sansui 9090db (receiver TOTL) Luxman m120a (power amp) Pioneer SX1250 (receiver)
I only have experience with the luxman. I would presume that with your extensive experiences in audio and more extensive survey of the literature online and offline, you'd have gained perspectives on each of these great models.
Foo.
