lordfoo, ganda ng mga units dyan sa manila. Sandawa and I have been very frustrated here in Davao. No more high end units. I have been wanting to score a luxman here but no luck. congrats on your purchases.

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. with price not a factor, here's my preference: 1. AU-D907X Decade 2. M-120a 3. SX1250 4. 9090dB

are you kidding ;D? do you have plans of selling it? i'm quite interested. got the 530, and 540, but the 540 arrived here in Davao defective (transformer is missing). the 540 is twice more expensive compared with 530 and a collectors' item. i'd probably rate it at par with the best of the Alpha 907 series of Sansui and better than comparable integrated amps the Brits could produce. here's a German site with 540 photos: www.audioinnovationen.de/html/luxman_l-540.html

you have an Acoustat? back in mid '80s, among my dream speakers were electrostatic panels of Acoustat and Magnepan/Tympani (also Quad's). but i was just a poor salaried worker who can't afford such wonders, so i got small but excellent Brit speakers as well as mid-sized US boxes instead. in the last two years, i have learned to appreciate good Jap speakers too. btw, i think you know very well your Luxman L540 could handle Acoustat. teka. i think we're contemporaries, you're an oldtimer in this game too! nice to have someone like you on board - we can share a lot of stories .

i was already enjoying my newly acquired Luxman-L80, made in 1975, for several days until i realized last night i haven't checked its DC-offset ratings yet. i've no golden ears, unlike some members of this forum, so i took my multimeter and found the right channel with 4mV, which is okay, but the left channel swings to about 60mV. that nearly floored me since it indicates channel imbalance, which i hardly noticed, as per rules set by Echo Wars of Audio Karma: within the 50mV band - tolerable; 51 to 100mV - alarming; and over 100mV - evidently imbalanced, overheating, and relay protection kicking in. i had to open the amp to look for the DC-offset variable resistors, found 4 (two pairs), and took my chance on VR101s instead of VR102s. unlike those in Yamaha and Sansui, Luxman amp's VRs on circuit board have no labels. fortunately i was right and was successful in trimming down DC offsets for both channels at 2mV. below are photos of the Luxman amp including the innards and location of the DC-offset VRs: this was taken at the back of the amp. the VR101s are the dirty white buttons at the top next to the twin capacitor towers. if you're looking in front - from the faceplate - the left trimmer corresponds to the left channel DC offset. the other pair of VRs are for bias. i'm a sucker for wooden amp housing. the Luxman L-80 fully clothed. the vintage look of the frontplate. the Luxman L-80 nude. this amp was made as a golden anniversary model of Luxman, 35wpc, low-powered but sound quality is superb for its class.

congrats sir, the unit looks quite yummy indeed with the wood housing. and thanx for the pics, who knows one of our members here will one day have for themselves an L-80, laking tulong eto specailly if they will have to adjust to the DC-offset ratings. this is an integrate right?

thanks. that's precisely the objective. help vintage Luxman owners fine-tune their gear. btw, i got PM inquiries these past few days from members of other boards asking me suggestions on amps to buy. my constant answer is your 907X Decade.

Also, i noticed medyo madalas ang Luxman LV101, 102 etc. sa pier. What's the difference between the LVs and your L80? By the way, although I didnt get to buy Sir Wanderlust's TOTL sansui, I did get the non-working Pioneer SX1250. Its operational now but it still have some issues such as one channel is louder than the other. The phonostage is garbled. Also some problems with the tuner section. But its beautiful to look at when all the lights are working . But it beats most of the amplifiers that I have right now.

the Luxman LVs were made in '80s, i think, after Alpine took over and they do look better. the 907F Extra is equivalent to AU-D11 series 2. a lot of difference, considering the 907X-Decade is a limited edition that has no equivalent model in the international market. the 907X has but with a different model code (G99X yata).
btw, i also had an SX-1250 before, talagang malakas yan. i guess it's all a matter of taste, kasi my perception back then was masyadong malakas lumagabog even on materials that don't need to emphasize bass. it seems choosy on materials and is simply the best if you listen mostly to pop and rock.

thanks. that's precisely the objective. help vintage Luxman owners fine-tune their gear. btw, i got PM inquiries these past few days from members of other boards asking me suggestions on amps to buy. my constant answer is your 907X Decade. Guess it's time for me to speak up. I'm now the proud and happy owner of attorney's Sansui AU-D907X Decade ;D ;D Nakuha ko last October 1 pa ;D It's currently driving my pair of Tannoy 605's which I bought brand new (together with original stands) way back in 1992/93 I think. Unfortunately the source is a Philips CDC 486, a cd changer that I got from one of their bodega sales sometime in the later half of the 90's. I don't think ganun kaganda specs ng Philips na 'to so I believe the overall sound can still be improved once I find a better player. Saka since my speakers are quite small, medyo kulang sa bass kaya I have to use the bass tone control of the Sansui to compensate. Interestingly enough, even though I'm using the "Direct CD" inputs, the tone controls work as long as the "Tone" button is pressed. I thought the "Direct CD" inputs bypassed all of the tone control circuitry All in all I'm very happy with this amp. Not only does it allow me to separate my audio set-up from my HT, I also got one of the more exclusive vintage amps around. Thank you attorney ;D ;D

Congratz on the sansui 907xdecade acquisition ;D I had my eye on that unit of Sir Wanderlust. OT: Sir Sandawa... what do you think of advent speakers? Have you had these speakers? There was this pair in a thrift shop i frequented. I didnt find any model displayed on the front or back. Floorstander siya. The grills look like burlap. (parang made of Sack ang material.) It looked pretty old but the box is still okay. Mukhnang napalitan na ang surrounds. It was going for 6000. kaya di ko binili. But i seem to have passed through some comments on these speakers a long time ago at the AK forum.

Sir Foo,
maganda ang mga Advents but the one i was able to use back then was a smallish bookshelf, can't recall the model number - parang 3 or 4 - bought from an American graduate student doing his thesis on Southeast Asian fisheries and renting a room near the old BFAR bldg. in Quezon Ave.
hindi ko makakalimutan yun, his asking price was P4K but he gave it in exchange for a $100 bill - then equivalent to P2.5K, or my one-month salary back then.
ask your friendly thrift shop owner if he can find an AR-3a or a JBL-100 (Century). yun ang mga legendary speakers dito nung '80s. baka may magbibitiw na oldtimer, tapos mint condition/properly maintained. kahit P10K/pair puwede na.

Master Sandawa,
Wanderlust did mention that you wanted to get his amp too...but he also said that you were willing to let others experience one of these legendary Sansuis. I've read all your very interesting and educational posts both here and at the other forum and I knew I just had to own this rare masterpiece ;D. I envy your awesome collection of vintage gear sir.
Actually I had my first encounter with Sansui way back '93 I think. My former boss had a problem with an old quadrasonic Sansui receiver (can't remember the model). Being the super sipsip I was I volunteered to have it checked. It was a weekend and the problem was easily fixed. So I had that Sansui connected to my speakers for almost two days and boy was I surprised at how it sounded. From that time on I never forgot Sansui.
Lordfoo,
Thank you ;D You are another remarkable collector of vintage audio equipment.

I missed the Sansui AUD907Fextra at the pier. It was sold for 4800.00 at the pier. I don't know the condition. This amp i understand performs not as well as the AUD907Xdecade. Well I had that amount in my pocket so i toured the pier again and went back to two units i have been eyeing before. For the same amount, I brought home a while ago a Yamaha CA1000 and a sony VFET4650. www.thevintageknob.org/VFET/VFET-main.htmlwww.thevintageknob.org/YAMAHA/CA1000/CA1000.htmlBoth amps are listed at the vintage knob. I also saw a nice looking pair of onkyo speaker at the pier. Had them connected to both the sony and the yammie and was impressed with the sound. The left speaker faltered though at high volume. www11.plala.or.jp/se_ke5583/ONKYO/speaker/u-5000.htmlI was attracted by the horn serving as the mid drive. Didn't buy the unit. Foo

congrats! uy, meron ako niyang Yamaha CA-1000III. that's a collectors item. 100wpc and has a class A (20wpc) switch and very popular among Audio Karma members. its equivalent in the US is CA-1010, sabi ni Axel (TVK). good, balanced sound but a little weak on low frequency if pitted against my other amps. was sold at $600 in late '70s but still attracting bids of up to $300 in US eBay.
if i could still recall, its boards have labels for the DC-offset trimmers. it might be better to check the DC-offset ratings now and make the necessary adjustments for trouble-free performance in succeeding years.
