It's good you made up your mind and the insurance is the only way to go, I had to answer lots of customs and PO questions cos all of them were intrigued by the high value of the product, made me open the box, explain etc. They even stopped it for a month in Holland, the military PO.
I think when they see the generic "music player" description they expect to cost 20$ and only know about MP3 players. Not to mention all phones today "play music" so... we are for sure drug dealers or terrorists hiding smth bad in the box, why would anyone in their wright minds pay so much for a strange box when you have all the music you want right in your pocket?!
If you use your iphone or ipad until your next player try Onkyo HiFi player app, pay it full version and put WAV files through transfer option in iTunes, 11band EQ set to HiFi EQ as option and at least on my setup with or without Fiio E 17 amp, Westone 4r or JBL S700, I really enjoy, even on the EarPods I think I hear differences, though I'm not really shure about that.
