BOSC™ - 150W HiFi Monoblock GaN Audio Amplifier

---

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 an 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 an easy-to-use small package that will blend into 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."

Jack Roberts - The Audio Beatnik

" I found them very dynamic, very musical, and beautifully detailed in the top end. The tone was better than in many transistor amps. The same could be said about emotional involvement. Listenability was very good with a relaxed and detailed sound. The soundstage and imaging were also very good. "

Michael Connelly - Audio Nervosa

 "Bottom line: I thoroughly enjoyed my time with the BOSC amps and think they form an amazing combo with the PecanPi Streamer.  Their strength for me is that they were able to take what was a background music system at best to something far, far better.   I have no doubt that they will shine best when matched with a high-quality pair of speakers.   If you like your music open, honest, highly engaging with life-like detail readily conveyed, I think these are absolutely worth a listen. "
