    Hi,
    Ever since I heard a g8000 I wanted to own a Sansui vintage.

    The following amp's is available for me to buy, but I can't hear or compare them first.
    Hope someone could help me with input on these:
    AU7500
    AU5900
    AU417
    TR707a

    The first 3 are tough, but I would pass by the last one on your list.
    The 417 would probably be my choice.

    They would all require some work however, unless already 'properly restored' the AU-417 will require the least work.

    The TR707a is probably the peach of the bunch, but would require by far the most work.

    The 5900 looks in very bad shape externally. So I decided to pass on this.
    The 7500 look excellent on the outside, the plastic film on the front is still on!
    The 417 look good.
    Inside pictures look stock on all.
    Seller says he restore old amps if needed, so it might be ok (if he's skilled).

    There's also a 5050 for sale from another guy, the seller says one channel on this is sometimes a bit lower than the other.
    When turning volum this corrects itself. Maybe just a cleaning issue?
    The externals look very nice.

    I'm not experienced in fixing amp's, so that could be a (big) issue.
    Maybe I'll take water over my head to go vintage? (Want to learn to fix, but where to start?)

    I also found a very nice alpha 707dr, but it is expensive... (1k $)

    Seems like based on the above comments, the 417 may be the winner. It shouldn't give you much or any trouble if its already working OK.

    I had a 7500 and depending on your speaker sensitivity - you may (or may not) find this noisy (hissy).

    A 5900 in good condition would be my personal pic - but it all depends on what YOUR situation is of course.

    What speakers will you be using?

    AU-7500 but if you had a choice of a AU-517 then the AU-517

    Thanks for your feedback,
    I realize flavor of sound is different on these amps and there are different opinions and speaker matching will differ.
    If I want a smooth live music type of amp.
    Emotion more important than analytic sound
    Good deep bass with good rythm, not to sharp or forward in the treble (rather a touch relaxed)
    Will this narrow the choice? Or they're to similar to conclude?

    Should I wait for a 9090db or g series instead?

    .

    Of the G series, the sound is well regard as the best of the best of the best that ever was.
    *edit (But as other make a point of, AU is as good or better)*

    also, avoid the 9090 DB and opt for version without DB.
    Dolby circuit in db very problematic
    and for the few time (if ever) you use the circuit,
    not worth the hassle of hard to find parts when it goes bad.
    I have not use Dolby in 35 years,
    was more about marketing than about necessary circuitry,
    I think is almost useless, unless to make audio tapes
    and most tape machine have dolby build in
    so db circuit in amp is redundant and problematic.

    -If it was the 8000 you always like, I would wait for Sansui G8000,
    Persons are never happy until they get exactly what they Always have want.
    if you get one of the other listed, you will always thinks about how much better/worse 8000 is.


    cordialement,
    moe of the north

    Easy Mo, :) receivers 'are not'/'were never', the only game in town - Receivers are available in the USA particularly, but everyone should know that integrated amplifiers like the AU-9900, AU-9500, AU-999 (modified), AU-919 and AU-X1 can be a better choice - but often more difficult to find, and can be more expensive - I wonder why? (there are others - absolutely not an exhaustive list). If you don't need a tuner get 'an integrated' - with the advent of 'Internet radio' and 'streaming' this is more than ever the case.

    (dons flame suit, retreats to nuclear bunker, :D)

    Yes I suppose big Sansui are more common in USA, but not so much where I live.

    For sound, I think it would be very hard (but not impossible) to tell them apart when side to side,
    Still Sansui would have been on top of it's game in the 70's
    and owners ears/eyes determine which is the favourite.

    Yes I agree, Both for Sansui and it's competitors, The 70's were the cream of the crop
    for G and AU series.
    My point is, grass is always greener with the thing you don't have (or always want to have)

    I would wait for the 8000 instead of always to think 'I should have'.

    -But some people are lucky and can have a nice collection and others
    maybe needs just the 'right' one.

    I would like to have one of each the big A AU integrated/amps, I have not to own not a single one yet.
    But of Large G Receiver, I can not pass a good deal even if I must have to sacrifice
    my wifes new birthday present of a bigger ironing board.:rolleyes:

    I don think you can blame the Sansui amp for noise/hiss,
    Exceptional clean circuitry and design.

    Perhaps regular maintenance or other problem yes?

    Thanks for your input guy's, appreciate it.
    Tuners are unfortunately not very useful for me in the future, FM is replaced with digital dab+ by 2017 (acc codec mostly 64kbs, horrible sounding...)
    9090 gets praise and look is fantastic , but it could be risky regarding Dolby board. A valid point.
    Moefuzz is very correct in his wise words about what triggered the "want" feeling is what you need to get to satisfy the feeling.
    The g8000, most importantly I have heard it and loved the sound of it. I know what I get.
    The against is price and availability.
    How will the au-7500 or alpha707dr be compared to a G8000?
    Other sensui integrated who compares to the sound signature and quality of the G8000?

    I think quite truthfully - very sensitive Fostex speakers.

    I've had one 6500 and two 7500s - restored them all but couldnt get rid of hiss, so flicked them on......

    This is compared to sound from other Sansuis I have had - 555A, 888, 999, 9900A....

    Hey moe I have four AU-X1's( but one is a parts unit) and I might be into trading one for the right thing anyway.

    My restored unit is dead quiet and almost as good as my 8D.
