Swapped one of these in place of my approx 10 yr old Yamaha Natural Sound Rec/Amp. This Pioneer blows it away.
The Loudness and Tone 'boost' add a richness and no distortion boost to the over-all sound - I leave them on all the time, otherwise the amp sound a bit too focused on the high-end to me.

A great piece of amplifier! beautiful vintage look and full bodied sound. I have mine (version mkII) fully working in AAA conditions playing with B&W 606 s2 Anniversary Edition in biwiring, it is just amazing!! The speakers just fly with it! only 30 watt on paper one can argue... but they are much better than many 100 watt modern amps, believe me or... believe your ears if you have the chance to give a listening to it!

Very capable little amplifier featuring Pioneer's beautiful silver face layout. Spartan and efficient at 25 watts per channel this little guy will drive most speakers thrown at it. A real classic and a joy to look at especially when paired with the TX-6500 tuner. Don't hesitate to add the SX-6500 to your collection.

Fantastic little Jap amplifier with smooth clear sound.
Owned since 1978, still goes strong.
