I don't own a Blackbody, but I borrowed one for about 3 weeks. I share the experience of others above. I heard more details, less noise, bigger soundstage. Strangely enough the music also sounded louder. I'd say its performance is in line with all other Lessloss products all of which I have tried or own. Ultimately, I didn't buy it as I'm not sure whether that is where I should put $1000 if I wanted to improve my system now, but I may buy it in the future.
