This little amp can drive my old, inefficient Wharfdale floor speakers with plenty of clean power to spare

bad power supply

It delivered crisp clean power with a killer sound stage

Amazing little amp, big on clean power

Definitely not enough power from the 19V power supply.

Fake power switch

More than enough power to get the job done

I read a lot about possible damage to speakers through under-powered amps as well as concerns about distortion if you need to max the amp out to drive the speakers, so I wanted to get one that would have enough power to drive the speakers without needing to max it out
