Amazing performance. Much better then the SA-940. I now use the 940 as a preamp to the 540 equalizer and then into the SA-1040 and have the cleanest LP sound for my setups thus far. Played back on CS-A9000’s.

9/10 for the LED’s. I have a few of these units and the LEDs all have slight issues. But still work on the upper end.

re: SA-1040

I bought one of these also for around $ 50.00. Some light rust inside (looks like it was stored in a basement).
I am in the process of restoring mine. Let me take a moment to curse Pioneer Engineering department. Many of their cheaper receivers had NO access to the bottom!! The entire circuit board must be removed much to my dismay. Pioneer improved on this one but unfortunately you cannot get to some of capacitors and regulator because the bottom cutout was only about 70% of the receiver. Very poor design. There is no reason that the entire bottom panel should not have access. Also the extremely cheap power meters rarely work. I was surprised to see the one on this video does work. I own many of the SA series. I will say they are a cheap (price) but pretty decent amp but a bit harsh sounding in the upper ranges but good for casual listening. They are very reliable and a good bargain.

re: SA-1040

Jim, I would have to agree with your assessments regarding serviceability. I picked up an SA-1050 on the cheap. I am not sure what the difference between the two models is? Mine sounds good and the only problem it has at the moment is with some of the LED power meter, some of the segments are out. I spent a little time fiddling with them to see if it was something simple. Unfortunately it does not seem to be an easy fix. Did you dig into yours at all to see if you could find the cause of the trouble? Just curious. Best regards,
