Yes Sainsui , It IS surprising just how cheap you can pick up these little PIONEER integrated amps. I bought "BOTH" a SA-750 AND A SA-950 (70 WPC) for $15.00.sainsui said:
(IMHO) these are fairly ugly units BUT , I'll be damned if these units don't sound "ALOT" better than I would have expected. 
pound for pound the best deal in vintage amps
They rock they roll, there ain't no gettin' around it Mikey boy! Both my SA-940 and SA-1050 are as mint as can be and I'll stack 'em against the big guys anyday. The SA-940 is the more impressive of the 2 IMO. I mean my God at a paltry rated 70 WPC it'll flat pound my MTX AAL212s and my JBL C150s all day long and never get warm to the touch! And there's a hint, if you haven't heard the MTX AAL212 speakers you should do so, they might be one of the biggest kept secrets in hi-fi history, sounding better than even the MTX AAL15's.

Pioneer SA-940
I Bought the SA 940 + the tuner TX-950 in The Netherlands in mint condition, from the amplifier I have the manual: 2 x 87 Watt/ 8 Ohms/ T.H.D. 1 %,
2 x 70 Watt/ 8 Ohms/ T.H.D. 0,009 %(!)
Damping Factor 100Hz/ 8 Ohms: 60.
I've sold my Onkyo A 8057 for these: on my IMF's ALS 40-II the Pioneer performs much better.

I realize this is an older thread, but just had to chime in.........I've been around what I thought were knowledgeable "audiophiles" for many years. I had always been told that all that matters is how many watts per channel and had to be 1970's only,LOL.
I just bought one of these (SA 940) and the thing I've noticed most on all the amps/integrateds I've owned over the years had one thing in common. The best detailed and powerful amps (no matter the wattage) were rated at or above the 50 mark when it come to dampening. From my understanding of dampening, it is the rate that an amp recovers from "peaks" produced and relates to how detailed an amp can reproduce the sine waves quickly. Therefore better detail/separation and fidelity (richness) of sound.
THIS little jewel does it quite well, IMHO. and I paid 100 bucks for it in pristine condition in Nov. 2020...............worth every penny and will be using as my main system replacing a 120 wpc Yamahammer that cannot compete. I listen to a lot of Jazz/Rock/Blues/Fusion and acoustical music and this is what I've been missing all these years. Could have saved myself $$$$$$$$$$ over the years, LOL. I highly recommend anyone pick up one of these before people find out they are not just another 1980's cheapo build.

They have a cheap look and often times the power LED indicators fail on them. with that said, they are pretty good electronically built units. I believe the SA1050's even have two capacitors for each side if I can remember correctly for a total of four. They sound pretty good for the price. The lower you go down in model numbers the more harsh they begin to sound. (SA) line anyway. 70 watts and 100 for the larger model. While they perform very well for their price range I would not compare them with the Sansui G series. For some reason Pioneer decided not to put access panels on the bottom of these so they were harder to work on they should be restored at this age all the capacitors are nearly dead on these takes a little bit of care but it's not too awful difficult to remove the circuit board and restore these change the capacitors. Pioneers claim to fame was the so-called non-switching power supplies. I think that was just a marketing gimmick. I found these models slightly harsh to listen to for extended periods but had a great bang for your buck ratio. I think the newer plastic series(example )sa 930 receiver sounded a bit better but they were built out of plastic unfortunately.
