  1. I probably should be holding off on creating this thread but I've been so slack lately that I haven't had anything to post about and the lack of anything to write has me breaking out in hives so I thought, what the heck. Maybe there is no time like the present. Deep breaths, deep breaths and here we go. OK so... this was bound to happen eventually. I’ve found I like a certain manufacturer so much I just couldn’t help myself and went and bought up several of their amps to see which one sounds the best to me. I would like to start at the beginning of this story but that would just be confusing since I didn’t buy them in order and they certainly didn’t arrive in order and I started buying them long before I made the decision to buy the rest of them and turn the whole ordeal into a massive comparison. So I’m going to start where I feel the beginning should have been and then I’ll try to move on towards where I think the middle should be, and then on to the logical conclusion. Things will be much less disjointed that way. A little history behind the decision, I bought the Sansui Alpha 907NRA back in December 2016 and liked it so much I hatched a plan. I would buy another Sansui Alpha, have a bit of a listen to that and then use this second amp as a trade/gift/incentive to get either Pete_mac or Skippy124 to give the NRA a full service. It seemed like a good idea at the time so I went for it. Unfortunately the second amp (an Alpha 907DR) had performance issues on arrival and has spent most of its time in Oz sitting with my nominated tech/repairer, so that plan didn’t really turn out as conceived. While I was waiting for the DR to arrive I found this thread on AudioKarma: http://audiokarma.org/forums/index.php?threads/what-would-be-the-best-sansui-amplifier-for-sound-quality.450432/ And that started me down the track I would take that ends in this thread being created. I just wanted to know, and I wanted to know badly enough to decide to do something about it. I really shouldn’t have, it hasn’t been kind to my financial situation, but I decided to and I did and there’s no point in worrying about things that are now in the past (unless you regret the decision, and I most certainly do not, so it’s all good). The thread above is a long one but the thing which stood out to me was that the NRA was not a clear front runner. Of the Alpha series the general consensus, and it was fairly general, was that the MR was probably the best. Many people didn’t like the Alpha series at all and claimed that the 70’s gear was their favourite (likers of warmer sound I guess). Anyway, to my mind this thread didn’t answer the question it just served to make me even more curious to find out for myself. I decided to limit this thread to the Alpha series of Sansui Amps, because even my large amplifier appetite was not up to the task of taking on the entirety of Sansui’s back catalogue. I did toy with the idea of including the model prior to the Alphas, the 907X and/or the X Decade but these were a different design to the models that directly preceded them and those models (the G and G Extra) were different again to their predecessors. The 80’s was a decade of great change in the Sansui line up so it didn’t really matter where I started the question of “How does it sound compared to the model before it?” was always going to come up. So I decided to stick to the Alpha series, because lines have to be drawn somewhere. I have been taught a few things by conducting this importing exercise. The first is that freight from Japan is expensive. The second is that freight varies wildly depending on the company doing the sending even if the freight company is the same. Hifido for instance obviously has a sweet deal with Fedex as freight from them came to about 45% of freight from other senders in Japan. The third is that packing is extremely important and most people don’t do it well. Again kudos to Hifido as their packing is second to none. Other senders in Japan have varying levels of packing volume and quality, however if you ask for more serious packing they are usually quite helpful and the extra fees are quite small in the overall scheme of things. The fourth thing is that freight from Japan is expensive, this emphasis is important, in several cases the freight came to more than the auction price of the amp, should you even intend to import from Japan ensure you do not forget the fourth thing! My initial findings, long before I get into the nitty gritty of details are as follows. In most cases these are gleaned from just a few hours of listening so they should be treated as very preliminary. I plan to follow all of the reviews later in this thread with an update of this list of differences so that those who are curious will have a “Sansui Character Reference Chart” they can use. Sansui AU-α 907 The last to arrive and not yet listened to, sorry, you’ll just have to tune in later. Sansui AU-α 907i and AU-α 907L Extra I’ve only given these a brief listen to confirm they were operational, however from what I’ve heard they have a thicker sound texture to the later models with plenty of bass weight (probably a bit too much for my liking). They have a strange way of taking digital music and making it sound more like vinyl-ish. Sansui AU-α 907DR This amp needed attention but I can confirm that this is where Sansui really started getting serious with the top end capabilities of their amps. A decidedly better top end than the previous two models but still with a powerful bottom end and the beginnings of the spectacular mid-range that would come later. Sansui AU-α 907 KX A large improvement in both the top end and the mid range over the DR however it does this by sounding less smooth and more resolving so digital advocates are likely to like it over the DR but vinyl advocates may well prefer the DR. Less bass on display but far more articulate with it. Sansui AU-α 907 XR More bass punch than the KX and a bigger presence but very similar in other aspects. Sansui AU-α 907 MR Very much an XR with much more subtlety on display, more resolution, cleaner background and slightly clearer vocals. Unless you get them side by side it is pretty much impossible to tell the XR and MR apart, they are very, very similar. Sansui AU-α 907 NRA More polish present than the other Alphas, so clean in the mid-range it sparkles, so clean in the top end it shines. Has a mild bass boost effect that is not present on the other Alphas. There is also a ring in Sansui that I have yet to get to serious grips with, it also needs a little care and “technical attention” so I can’t really say much about it yet but I’m sure I will be able to later. In an effort to make this comparison more interesting I’m going to be using a Sansui cd player as the source. I have managed to obtain a Sansui AU-α917XR cd player in addition to all the amps. I haven’t listened to this cd player yet as it arrived needing new belts. I’m picking it up tomorrow and needless to say I have high hopes. Pictures will follow, and yes, there will be many.
  2. A question for all you Sansui-philes out there. If I was to chase a Sansui integrated amp to add to my demo list which amps should I look out for? There is an AU-555A on ebay at the moment, is that a good example of the brand or a bad one?
  3. The Sansui Awesome Foursome Review 2020. List on contenders; Sansui AU-111 (1966) vs AU-1111 MOS Vintage (1989) vs Alpha 907 Limited (1994) vs Alpha 907 NRA (1998). Might add another contender or two in the mix. I'd love a restored AU-X1 into the mix that way we have pretty much one from each decade. Thinking of a small gtg of passionate Sansui nutters only 🥴 It could be some time before this actually happens but stay tuned. Looking in August or September depending on the Cov19 situation. What are your thoughts or opinions on what will sound the best to you. What design do you prefer internally or externally with built quality Black, silver or gold. Functionality - features they offer Svetlana 6L6GC Power Tubes vs Mosfets vs NM-LAPT transistors. Mr Kosaku Kikuchi vs Mr Ichirou Ohshima designs
  4. Further information: Good working order, was serviced recently. The power lamp was replaced with a LED. Photos: Advertisements without photos of the actual item will not be approved.
  5. So I recently purchased a little sansui au101 that has an issue where it is blowing fuse f003 for the right channel. I have since recapped the entire unit and replaced all transistors with suitable replacements but the problem persists. I also replaced the trim pots with multi turn units and I am able to set steady bias at idle however I have discovered that when the amp is receiving audio input with my multi meter attached to the emitter resistor r838 the bias jumps through the roof putting out distorted crackly sound which will then blow the fuse due to excess current. I have spent ages inspecting traces and solders, testing resistors etc but seem to have hit a dead end with it. Any help or suggestions where to look next would be greatly appreciated?
  6. Item:Wanting to buy Sansui TU-7900 tuner Price Range: Neg. Item Condition: New or Used Extra Info: I’m in Brisbane,so willing to pay for postage.
  7. Hi Guys, Need your help and suggestion. I am looking for a modern alternatives to vintage Sansui integrated amps, particularly Sansui AU series (AU-217, 417, 517 and so on). I had a Sansui AU-217 MKII Vintage Amp for a while and was very happy with it. While my speakers have come and gone, I did keep up with that amp. Over last year or so, I have been working more remotely and needed a setup on my desk, so I went around and bought the Sonos Ones with Sonos Sub as my desktop setup for ease of use and less space. This worked well, however one day I brought out the Vintage amp and set it up on opposite wall to listen to some old speakers and I was blown away and immediately regretted having this replaced with Sonos. So, I sold the Sonos Setup and have been listening to Sansui amp with vintage and DIY speakers. Last month I upgraded my Home theatre speakers from Ascensions speakers (Edward's speakers from Adelaide speakers), and needed some fund to pay for it. So, the vintage stereo setup had to go and I ended up selling the Sansui amp and the speakers. I still have my DIY speakers hooked up to friend's old Pioneer AVR receiver. Day by day I am missing the Sansui Amp and regretting the sale of it. This brings me to my quest to find the alternatives in modern world. Finding decent Sansui AU series amp is hard here in Australia and just as expensive as the modern units. so the question is are there any modern alternatives to Sansui AU series with similar sound signature. My budget is around $400 to $600. I have been eyeing Marantz PM5005 and Rotel A10 in that price range. However, can anyone recommend me a modern amp that sounds similar to Sansui? I am not fussed about the connectivity as in Bluetooth or network connection in amp.
  8. Further information: It was refurbished. All capacitors were checked. Critical electrolyte capacitances were replaced with WIMA one. The power lamp is replaced with a LED. The BIAS adjustment is done. Speaker terminals are upgraded. https://www.hifiengine.com/manual_library/sansui/au-101.shtml Photos: Advertisements without photos of the actual item will not be approved.
  9. Further information: This magnificent Sansui receiver came from the ANU school of music recording studio, where it was used to drive altec monitors.(note the sticker from Canberra institute of the arts- one of many names covering the school of music over the years) It works fine- as a pro use studio amp it was very well maintained. One curious feature is that the tuner is AM and Short Wave (MW ). They are photos of the actual receiver below. I am in Canberra and can post anywhere. Postage should be between $25- $45 depending on distance OneBay these go for about $280 so this is a steal From the HIFI Engine: Power output: 30 watts per channel into 8Ω (stereo) Frequency response: 20Hz to 20kHz Total harmonic distortion: 0.05% Input sensitivity: 3.5mV (MM), 200mV (line) Signal to noise ratio: 75dB (MM), 105dB (line) Output: 200mV (line) Speaker load impedance: 4Ω to 16Ω Dimensions: 430 x 136 x 311mm Weight: 7kg Photos: Advertisements without photos of the actual item will not be approved.
  10. Item: Sansui AU-X501 Integrated Amplifer Location: Perth Price: Sold Item Condition: Good Reason for selling: Funding new purchases Payment Method: Pickup only - Cash, Paypal, COD Only Extra Info: I was recommended this model by a number of the incredibly helpful (and wise) Sansui gurus on SNA. I paired it with some usher s520 speakers which can be a bit clinical and are fairly inefficient - fantastic match - but it was equally happy driving some bigger Sony APM 3-ways. I’ve really loved the amp – heaps of power that belies the rated 80 watts and a very detailed, lively sound. It still seems to have some of that Sansui warmth, but more modern and transparent than the 1970s gear. Very nice phono stage with MM/MC switch. As prices of the earlier Sansui amps have gone through the roof in the past few years, this model appears a bit of a sleeper - the smaller brother of the x701 and x901 which I think sold in Japan with the alpha prefix (Sansui nomenclature is not my strong suite though). I haven't even had the lid off this one, because it all seems to work fine. I think it’s basically untouched under the hood. There’s no crackling I can recall with any of the buttons or knobs but given the age it probably could do with a deoxit. I’ve not checked the bias nor any of the capacitors to see if they’re in spec – again probably worth doing at some point for what’s now I guess a vintage amp. The main filter caps are Elna for Audio which should hint at decent quality components. I’d conclude the condition is cosmetically pretty good for the age although certainly not mint – the black mirror painted aluminum face on these is hard to photograph as it just reflects everything, however the front is quite clean. I've tried to depict it as honestly as I can. Some of the black paint has worn in a thin line on the top edge that gets touched a lot – this seems like a common thing from other units I’ve seen on the web but I didn’t find it that noticeable and made no attempt to touch it up. The previous owner was kind enough to sand back and respray the lid with a satin black finish before handing it to me and I think he’s done quite a decent job. Finally this unit has some SNA provenance which I quite enjoy – I was browsing the site looking for other examples of the x501 and noticed that @Vortexjah had posted one for sale in 2013. Pretty sure I checked out his listing and the comments when I was considering buying mine. For some reason I was minded to cross-reference the serial number and bugger me if it isn’t the very same one! We worked out that it had gone from @Vortexjah in QLD to a guy in the NT, and then was purchased by a chap on a trip to the top end who brought back to Perth for a few years before he sold it to me about 18 months ago. It looks pretty much the same as it did 7 years ago! Be nice to keep it in the SNA community. Photos: Advertisements without photos of the actual item will not be approved.

  13. Item: Sansui AU-D33AU Integrated Amplifier Location: Balwyn, Vic Price: $170 Item Condition: Good *see below Reason for selling: N L R Payment Method: Pickup - Cash, Paypal Extra Info: This is the amp I grew up with. Possibly the reason I got into this hobby in the first place. It has some minor cosmetic blemishes on the top and the binding posts need some work as they are old and plastic and like to catch. Nothing a keen hobbyist couldn't fix easily. I have poked some fine cable through to connect to my thicker more recent design of speaker cable. It still sounds great! 50w P/C I think from memory.

  15. Item: Sansui AU-α607MR Integrated Amplifier Mel Location: Melbourne 3183 Price: 1250 Item Condition: very good. Recently was serviced. Payment Method: Pickup - Cash, Paypal +PayPal fee Extra Info: 907MRX was the only amp awarded in Japan in 1995. 607DR is similar to 907DR. The sound is the same but bit less power. Copper screws say a lot about the amp quality. It is built as a tank. Sansui AU-α607MR was sold in Japan only. It is need 100V power supply. Comes with a high quality isolated 500W small size step down transformer. \ No remote control. I believe that a buyer will not be disappointed. The sound is so clear that you can hear a musician breath. But what is most impress me is a high frequency bell sound. I have never heard in my live so nice bell sound. I have had a lot of amps including many Sansui amps but only this one can do that. It is just smoothly slow disappearing in air. Amazing! How Sansui could do that? My Luxman makes bells well too, but I prefer Sansui bells. Sansui bells sounding like inside a church whereas Luxman is outside one. Specifications Power output: 90 watts per channel into 8Ω (stereo) Frequency response: 0Hz to 300kHz Total harmonic distortion: 0.003% Damping factor: 150 Input sensitivity: 0.3mV (MC), 2.5mV (MM), 150mV (line) Signal to noise ratio: 70dB (MC), 88dB (MM), 110dB (line) Output: 150mV (line) Speaker load impedance: 4Ω to 16Ω Dimensions: 430 x 162 x 452mm Weight: 18kg Year: 1996 Photos: Advertisements without photos of the actual item will not be approved.
