I skipped the Vali on purpose, just didn't have much interest for various personal reasons. I know that I won't ever buy one either regardless of how good it's supposed to sound, so I just passed it by. I'm usually more in the market for larger desktop-size solid-state amps and closed portable (and full-size) headphones. There were a ton of IEM vendors that I skipped as well, as I'm just not interested in IEMs either right now. The only reason I'd buy an IEM would be if something happened to my JH13 (broken, lost, stolen, etc).
In fact, if I had to identify the top trends in the market based on what was at RMAF, they were: (1) IEMs and portable hi-fi (the Astell & Kern players were everywhere, not just at Astell & Kern's table!), (2) computer audio, especially on MacBooks (how come no one ever uses a Windows laptop at audio shows?), and (3) closed portable headphones.
