Pioneer believes in music. And if you do, too, you'll find a faithful friend in the new SA-9500; one of the most musically minded pre/main stereo amplifiers we've engineered.
It combines massive stereo output power with a delicacy of transparency; a rare blend in these days of lots of power at any cost.
In other words, we haven't simply beefed up the power section at the expense of the tonal quality, frequency response or other aspects so important to the sound of a high fidelity component.
The Pioneer SA-9500 does deliver an unusually large continuous power output of 80 watts per channel, min RMS at 8 ohms from 20 Hertz to 20,000 Hertz with no more than 0.1% total harmonic distortion, but it also ensures that even when operated at low volumes the performance retains a crisp, sparkling clarity.
The dynamic response and reliability of the SA-9500 are matched with a flexibility of use you'll rarely find in this price range. Tone control versatility, for instance: both the bass and treble sections have 3-position turnover selection and there's a tone on/off switch for "flat" response at a touch.
The 2-step high and low filters, the extra convenient tape duplicating switching system, multiple input source selection, 2-system speaker switching and much more mean first-class handling.
We believe in music. And we're sure that if you do, too, you'll believe in the all-new SA-9500.

    1. Thanks,i was collect information about my amplifier :)

  2. Thanx for the page. I am 54 yrs old and I have wanted one of these for a long long time. Just found one in great is more than I imagined!

  3. Great, thank you! I love mine. So you know if there's another one out there available for purchase? This is a time where two is definitely better than one! Email me if so. And thank you again for your time and consideration. B

  4. I bought mine in 76 on deployment on the USS Pyro for $220 through the good offices of the United States Navy (we were given a glossy catalog of nice things from Japan we could bring back duty-free a few weeks before we went home). How I wish I had bought two! Even though I had bought a Pioneer SX-727 (the first phase-locked-loop tuning section ever) in the Army in 73 I still didn't understand that Pioneer was in the same class technically with the fancy stuff (Crown, Marantz, etc.). I started to get the picture when I had it serviced in the early 80s and the tech checked the THD+N when he was done as was his custom. 20Hz-20kHz: .04% pushing over 100WRMS into >8< ohms!
