The guy cant even tell you what it is that he is selling? But started at $500? Unless you get a really good price on it, Id pass.
Whatever it is, its not an LMS, so chances are it cost less than that $500 when it sold new (before that over night AudioPulse price hike). Dont let the TC/AudioPulse hype talk you into paying premium money for an unknown item.
Maybe Thilo was right after all. Seems after his price hike, everyone thinks even the average AudioPulse drivers are worth big bucks. Not saying that in this case, just in general.
