I have just under 15 hours of use on my new 803 D3s. I'm glad these speakers have casters with retractable spikes as I'm still trying to dial them in. Excellent imaging and soundstage. It's always fun to hear a "new" detail on an well known track of music. They haven't quite "disappeared" yet and I think it may take as much as 100 hours to start to hear their true character. Thus far, I am very pleased with them.
