Small, But Packs Massive Punch

BOSC monoblock audio power amplifiers were conceptualized to provide the listener with a truly life-like musical experience, presented with every significant detail intact, in order to convey a truly emotional connection to the music.


BOSC amps use the latest state of the art electronics, including gallium nitride (GaN) technology to achieve ultra-high performance in a easy-to-use small package that will blend in to any decor.

Review(s):

Adam LaBarge - The Audio Beatnik

"I wanted to stop my heart so I could hear the music better. I was being sucked in, pushed out, and unable to focus on anything else but the music. There were all the little bird-like chimes, dancing between clicks and pings and bongs of xylophone harmonics with dry reed raspy sounds zooming in and out, floating on top of deep rolling strings and organ-like bass. I didn’t want to miss a moment of it."
