This was my first major purchase and my first foray into the audio world I bought a 1979 SX-580 for $245 taxes incl in London Ontario Canada. I was 16 years old and it took me forever to save up the money but it was worth it. These late 70 Pioneers were fantastic the build quality was Top Notch, the tactile characteristics were wonderfu...l who doesn't remember spinning that weighted tuning dial and watching it slide all the way down or the push of a spring-loaded high end button, turning of the knobs.. it had a great feel to it which many receivers have lacked ever since. For an entry-level design it put out a wonderful 20 watts a Channel of clear, clean sound across the Spectrum: as in 20 - 20000 Hertz.. with very low harmonic distortion the specs at entry-level are so much better than what you see today even with the mid and high range receivers. I absolutely cherished this little beast and used it daily for over 20 years until I finally upgraded to a technic receiver of the late nineties

I own a couple of these. Surprisingly Good sound and they come with POWER Meters and tuning strenth. I love these things. I restored both.
Great looks and very good build quality.

I found mine in an antique shop at a very reasonable price. I wasn't expecting much but I was pleasantly surprised at the build quality, sound and most of all its sensitivity. I get excellent reception using a simple dipole antenna. If you don't need a 150 watts per channel (wpc) to drive monster stadium speakers then this may be the gem for you.

Hi there, so this little Pioneer is my first Hi - fi reciver, and I just wanted to say some things about it. The sound is excelent, and you would be hard to find a new unit for under $100 that was even close. That said, it was a little low on power. My inital setup had two small bookshelf speakers. These worked great, and it definatly had more power than the speakers could take. I then upgraded to an old pair of rtr IV model B (which are huge, ineficent speakers). These, were a bit much. To drive the speakers at my listening volume it was pushing 20watts, and that was too close for clipping for my comfort (although, it still sounded great). Now, I am getting a bigger reciver for my main setup, and the pioneer will rejoin the bookshelfs in a bedroom. So, if you plan to power some newer , efficent, bookshelfs this pioneer gives you the vintage sound, without the cost.



re: SX-580

Would this one drive a pair of Mission 731, with recommended power between 25 and 75 W? I'd guess not, but if someone has a better informed opinion, let me know

re: SX-580

Yes of course. But not for large room size. By the way,SX-580 is just a pale face SX-590. I have a SX-590.
