The Sansui AU7900 integrated amp is a great sounding machine. I bought mine new in the summer 1977 along with a TU 7900 a Sansui SR-525turntable and a pair of Technics SB6000 2-way speakers. It was a great sounding combination. I was on a tight budget at the time. The amp was $399.00, Tuner was $299.00 the turntable I know was under $300.00, and the speakers under $400.00. I found it hard to listen to at a lower volume setting. When the volume was halfway open it was loud and crisp. Anymore than halfway it was like sitting in a speaker at a concert. The amp and tuner have had no problems since new. I would like to have them gone through and checked for issues and maybe recapped. The turntable has an issue with speed control I need to have fixed one tweeter has gone out and needs looked at. Otherwise this setup has been a good one I hope to have for another 40 years. If I can find another one of these pieces for sale at a reasonable price "and I'm on the same budget I was when I bought the first pieces" I would uy it again. It a great amp. No problems ever with it. Still sounds great. I bought the same amp and turntable a year earlier and my house was flooded. Turned it in to insurance and started over. I would do it again if I could find them.

This is one of the best sansui classic black beauty. I am totally impressed with the sound and planning to get an extra for spare. It has a good sound stage and sound warm and planning to recap it when I have free time. I prefer this amplifier compare to the newer sansui such as AU 717.

I was looking for an amp about a year ago and came across this beauty at a used-audio market.(For 150 euro it was quite a steal anyway). This little monster is great.

Build :
It's built and weighs like a tank. At the back there is a large heatsink (kind of rough though)the inputs/outputs and speaker posts facing up. The knobs are great to look and operate (no plastic here) and the overall looks with the black fascia is great. Minor complaint, the power cord is fixed and could be

I've had this amp for 30 years now and I still think it is outstanding. It's had everything thrown at it - hard work (used to drive the mid / high range units in a 1200 watt system), rough treatment and some easy life on occasion. It has taken everything in its stride and sounded like it could do even more.
Lovely, clean sound - nice and punchy when you want and never sounds like its straining.
I'll never part with it - true love !!!!

Not too many out there anymore. I was looking for an amp about a year ago and came across this beauty at a used-audio market.(For 150 euro it was quite a steal anyway). This little monster is great. Build : It's built and weighs like a tank. At the back there is a large heatsink (kind of rough though)the inputs/outputs and speaker posts facing up. The knobs are great to look and operate (no plastic here) and the overall looks with the black fascia is great. Minor complaint, the power cord is fixed and could be better. Anyway it can be replaced easily. Features: It's full of controls (2 muting options, filters, loudness and triple!! tone controls (bass,mid,treble) to experiment with. Still I think the most neutral sound comes all filters and tones off. It also comes with 2Aux, 2(!) Phono Inputs(MM/MC),Tuner,and 2 tape and a headphone output. By the way there are two speaker sets. Since there was no manual I am not quite sure about the output but I believe it to be rated at about 60-75W. Sound: The sound is clean, realistic , full of rythm never edgy or harsh but without becoming blury or lean. Quite a piece of work. A friend of mine owns a Sansui QRX6500 receiver (which as I recalled sounded great despite its years) and I really wanted to compare the sound so I had her to bring it over for a listen. What a friend (Ever tried to lift a Sansui?). All in all the sound is quite similar with main difference in power and presentation.While AU-7900 sounded more clean,detailed , the QRX6500 sounded warmer, rounder but less analytical though (not foggy). I wonder if the QRX's wooden cabinet has anything to do with that. AU-7900's cabinet is completely metalic.What they do have in common is how great music they both play.(Still I'll miss the reciever part). Sum up: Great amp at a no cost price.Don't think twice, if you find one that is..

Strength:

versatility, durability

Weakness:

Temperature

This seperate but still togheter combination of a parametrical equelized pre-amp and amp is a beauty to look and listen to. The 2x150 watt mosfet block has power enough to drive some serious speakers. The overbuild powersupply with two huge elco's has no problem dealing with low impededances. The machine runs stable at a two ohm load.
The soundquality is outstanding compared to the sony receiver at my parents house. The speakers, a pare of missions, came alive! I didn't know that the missions could produce such a high bassoutput. But in compare with my onkyo dual monoblock the amp lacks reality. The Onkyo produces the sound more clearly with more dynamics and closer to the record. The sansui tends to overdo the highs and lows but you can easily solve this problems by turning one of the twenty tonecontrol knobs. Outstanding performer in all conditions despite the incredible heatproduction (after an hour of playing don't even think of putting your hand on the heatsink)

I rate the 1970's Sansui products as having very high sound quality, good looks, and durability. The AU-7900 is a shining example of these qualities. It has 176 watts of power(it can blow the roof off the house!), flexible tone controls (Bass, Midrange, Treble). There are not a lot of amps on the market that have midrange control. There are tone and filter controls (Low filters are 20Hz and 60Hz and High filter switches are 12kHz and 7kHz) also for bass and treble, Loudness/muting switch, mode switch(mono, normal, reverse). There are 2 phono, tape(includes switch for copying deck 1 to deck 2, vice versa), 2 auxiliary inputs (for CD/VCR,etc) and 1 tuner input. There are also 2 sets of speaker inputs (A&B). Our family uses this amp to hear sound from videotapes when you hook up the VCR. It's pretty powerful especially when you have two set of speakers (use it to watch some action movies or even sci-fi when you hook your VCR audio outputs to the amp). We have had this amp for over 15 years, I grew up with this amp and can't find one that beats it in terms of sound versatility.
