I have had this amp since 1975. It is probably the best thing I have ever bought as it is still going strong. Switches and volume control are a bit noisy now but I have used it at a disco in the power amp mode and I never run out of power even in a big room. Reason not 10 out of 10 is because of the volume control. Better with a round knob than a slider.

I have a Marantz 1060, my recapped Sansui AU 6500 easily took its place. This Sony is superior to the Sansui. Can't wait to hear it with new caps.

I had one of these back in the mid-`70's and it was just a monster amp, but I foolishly sold it for moolah when times were hard.

In a line of Sony amplifiers nicknamed The Mac Killers because it was said that in a side by side comparison, to sound as good if not better than the McIntosh amplifiers of the day. That is enough said right there, but my experience with this 1973 30 watt amp is that it sounds better than may vintage 40 watt Marantz amp on my 1979 New Advent Loudspeakers in the real walnut cabinets. Here we have clear defined highs, where synths, strings and voices are not overly crisp or crackly. Lows are deep, full and warm with no audible distortion. Even digital recordings with their poor quality, muddy lows and crispy or harsh highs that are hard on the ears sound good on this system. For more info the HiFi Engine Library has a very good description of this amplifier and these loudspeakers.
