introducing brennan b2
The Brennan B2 is a Sonos compatible, high performance, highly featured CD Jukebox with a hard disk and power amplifier.
B2 has an internal 15W+15W power amplifier so it can drive traditional wired loudspeakers directly.
B2 also has optical and electrical outputs for easy connection to an amplifier or DAC.
When playing lossless recordings, the optical output provides a data stream identical to the original CD, meaning the audio quality is as good as any CD player, no matter the cost.

Quick and secure delivery of my B3. It was easy to set up and start to load CDs and my mp3 music files. I control the unit easily from my smart phone and laptop. I play the music on Sonos speakers and I am pleased with the results. There is a lot more to learn and try.

What Our Customer Say
"Best audio playing investment ever. I bought the JB7 back in 2010 with the BSP speakers, and added the B2, BB1 and EZB in subsequent years. Always received product very quickly after ordering. Love these products, and use them all the time. Best audio playing investment I have ever made in 55 years of music listening..."
