ChampionI don't own the HRT microStreamer, but I do have the E17. I have to say the E17 is a little hyped by all the reviews (i.e. at Amazom.com) and the navigation is terrible.<br /><br />Therefore in terms of sound I couldn't tell which sounds nicer between these two, but I personally wouldn't pay any more than $115 shipped for the E17. That's what I think it's worth, max.
