Very good detailing for an entry level amp.
Very soft yet powerful audio.

I bought this integrated amp along with the entire rack system new in 1985 to finally move up from an all in one compact stereo of the late 1970's.

The amp is probably the BEST thing about the whole system as by this point, Sansui was cheaping out badly from their days as good, solid mid level audio gear. I should know as my Dad had an early 70's 5000 series Sansui receiver, and the same vintage SP3000 series speakers (which I have), and I later got a pair of the slightly newer SP1700 speakers that I'm using now. In those days, they were well known for quality, with these vintage early 70's speakers being in cooperation with JBL, or so I've read.

Anyway, the turntable was a direct drive piece of junk, the motorized analog tuner was decent, until it began to drift off in the tuning capacitor about 20 years ago, the tape deck never was all that good, had a loose wire in one channel on the back of the playback head, and had AGC (auto gain control) for recording and Dolby B only for noise reduction, it never was anything more than a mediocre deck performance wise.

I later kept the integrated amp after the rest of the system eventually went bye, bye and used it for years as part of my computer audio setup until it finally crapped out on me a few months back.

Anyway, all I get is a loud clicking when I push in the speaker switch button, causing the woofers in my mini speakers to extend, even with the volume all the way down as I get a loud click. Plus, one of the push on/push on switches for the tape monitor went bad and had to be held in with a piece of stiff paper wedged in it.

It was repaired once in the early 90's when the large power amp chip went in the right channel, taking out one of my speakers with it by seizing up the woofer's voice coil.

I hope to fix this amp and relegate it as a tertiary audio system that can receive the music from the main system in another part of the house as when it works well, it sounds fairly good for what it is.

I bought this amp yesterday and it's sound is pretty good, (I state that it's my first amplifier) I listen music with a couple of Pioneer CS-313a and i like it so much. Yes, it's true, the design is a little bit ugly, just a little bit! xD By the way.. the important thing is the sound quality and I highly recommend it!

I found one at used items area, sound is good, with good bass, may be it needs recaping, or to check treble control as treble is not as good as bass

really like the Sansui A707...! state of the art attractive plastic for the 80's, sound's great simple design and easy to recap..! but the best attribute of all is how little $ you can get them for...!
