Very good review. Thanks

Thanks for your thorough review. May I ask your opinion of this vs. either of the two Fiio units you've owned (E17 and E7) in the past? Ratings-wise the E17 seems to be one of (or "THE") highest-rated combo DAC / Amps. I haven't made a purchase yet, but need something very portable, and works world-wide...as I am in various countries for work. Your suggestions and recommendations are welcome.
