I'm waiting on the X1. Supposed to be sold this month, but nothing yet. Once it does, I'll order it, compare to the HE-400 and then put one up for sale. The HE-400 still has it's place as I do enjoy it more for my preferred genres of music than the Annie, but for everything else (gaming, movies, tv shows, other genres of music), the Annie is king.
So it looks like I'm getting the 2011 Mixamp Pro (the auction ends in 2 hours), for $107 total (My Max bid was $120).
I'll be comparing it soon enough to the Marantz. I sure hope the hiss was as inaudible as the first gen Mixamp.
