Third@Third <br /><br />One of our vendors has access to 20 units of each (HE-400 and HE-500) and they're running the Massdrop. Hopefully HiFiMAN will change their position but for now It's all thanks to the vendors. <br /><br />That being said, the best way to get HiFIMAN to change their ways is to tell them how much you want their products listed by posting on their facebook pages, tweeting at them, and sending emails. We always tell them about the polls and votes but it's much more real when the customers are asking themselves : )<br /><br />Get in while you can!
