I bought in as a start-up in Sept 2015, and just received word that they are preparing to ship. Geeze ... after 2 years, I'm over it already! The new retail is $1399 - I'm selling mine as soon as I get it for $1200. I have an iPhone 7 128GB available for $200, too.
Everyone, and everything I listen to is my teacher. Every instrument, every voice, every sound in nature ... they are all my private tutor ... 24/7 for free.
