Randy,
Ok, thought you meant you were streaming internet radio or something like Pandora. Depending on how your streaming from your own server and the configuration of the dac and playback software, you should be getting great quality sound so I'm not sure why you said "just" streaming. or something like that.
Anyway, yes, the bass in particular on the Orcas starts to really fill in at about the 30-50 hour mark depending on how loud you play them. The spider and suspension need to work and loosen up a bit and ths accounts for a good bit of this. I'm running mine 24/7 now and will until later this month when I'm at or past the 400 hour mark. With my listening room being at the opposite end of the house from the bedroom, and down one level, I can get away with this, though it still can't be too awfully loud.
Continue to enjoy them and the amp!
