I bought the A-S3000 brand new. It was an upgrade sonically from their flagship integrated from 1985, the A-1000. However the A-1000 had a ton more power. Both amps were rated at 150 wpc @ 8ohms. I used the same speakers to compare.
I thought the A-S3000 was the last amp I was ever going to buy. That was four amps ago! Unfortunately, I had to upgrade from the A-S3000 when I upgraded speakers to a 4 ohm speaker.
The silver face A-S3000 is the most beautiful amp I’ve ever seen. It would be my go to if I lived in an apartment, the sonics at low volumes are really incredible! I’d also match it with efficient speakers. My old Infinity RS4b’s weren’t efficient enough. Their rated at 8 to 4 ohms.
