That’s what Robert says about his relationship with AER:
I loved the sound quality from the beginning, and then in 2011 I bought the AER AcoustiCube 3 as my first new AER amp to go with it to have a bigger brighter/wider sound.
This amplifier has also been with me for 12 years now without any grumbling or bitching. At some point I expanded the setup with a small, DIY-subwoofer. So I can either use one of the two amps on stage, or play in combination with the subwoofer over a small, great sounding PA. In any case, the sound is always crisp, clear and reliable.
