Extremely Rare SONY APM-77W for sale.

AMP means Accurate Piston Movement. It uses aluminum alloy honeycomb structure to make light and rigid square diaphragm to get rid of cone breakup vibration.

SONY speakers are all craps! true or false? It is true to the entire Sony speaker being sold now on Harvey Norman and Best Denki, but not true in History and during the golden ages of high in Japan before 1991 economy crisis.
As the number 1 electronics giant, Sony technically know how to build good speakers but the market is not good enough to make money. Most people only willing to pay for crap speakers and thus Sony makes lots of the craps to make money and survive.
Sony to occasionally make and demo some good speakers to show its technical capability.

I am a SONY fan and knows all the goodies from SONY, including its good speakers.
Let me name some of the good speakers made by Sony in history.
SONY AMP-8, SONY APM-6, SONY APM-4, SONY AMP-77.
SONY SS-GR1, SORY SS-G7, SONY SS-A7, SONY SS-G777ES
And the recently got stereophile class-A rated SONY SS-AR1

It takes the webmaster of the vintage knob 25 years to find one and he loves it so much and will never sell it!

If you missed this opportunity to buy it, it will never appear again in Echoloft!

Very good condition. No scratches.

$1.5k


Auditioning is welcome.
