The design of the AR-3 required a lot of power. I think around 150wpc would be about right and they will take more.

Thank you Russ69 i appreciate your answer. As i got the
opportunity to buy a Rotel RB 2000 who is 120wpc into
8 OHM and 140 wpc 4 OHM A&R ar3 are 4 OHM... I give me
4 week before to buy an used power amp so that give me
time to find a good digital cable and IC. I'm patient
so my buy will be the expression of my reflexion and
advise from other. Audio is a wonderfull hobby from
vintage Gibson guitar to high-end discovery of keep
secret best equipement...Where the good are not always
the most expensive.
I have had several AR3a's-powered by my old but reliable AR amp,it is 60 watts-per side at 4 ohms.They sounded great for the time but were never designed to play at super loud levels-the tweeters were the weak point.Whatever you do pick an amp with clean power-I made the mistake of using an old phase linear 400--it sounded great but I wanted it louder and louder and next thing I knew the tweeters failed-the AR amp was a safer bet-I knew what their limit was with it.
Friday i buy a digital coaxial cable and i just start the
burn in. The cable sound good already with the Meridian 565
build in dac. I buy a custom dealer made it a 1m Furutech
pure silver conduct with Furutech connector. for $150 cad
WOW,probably the best digital money can buy at this price range...
Upgrade is very audible much more details than the Sony
DVP-S7700 can deliver in CD mode now i use as transport
where it shine. The burn in will take min. of 125 hour.
So if you need a digital cable 75 ohm try the Furutech
FX Alpha pure silver with the connector of your choice.
It will surprise you...
