My BOSC are up and singing ever so sweetly via Roon --> PecanPi Streamer --> BOSC amps!
They sound every bit as good as I remember... detail and clarity galore with a tight and well defined bass. And all this in a secondary system overlooking my dining room and kitchen. I'm using an old pair of B&W bookshelf speakers that never sounded so good. My justification is that I told my wife i'd spend more time in the kitchen cooking. Hey, it could happen.
And I couldn't resist... I've also ordered a short pair of speaker cables from Pete @ Triode Wire Labs since the BOSC are sitting right next to the speakers.
Thank you Leo!
