I want to introduce my nephew to hi end with your help!

Hi guys, my nephew will turn 20th in June in Cuba and I'll be visiting him. He is a great kid and very curious about almost everything, he is finishing his second year of medicine. He loves music and always delighted to see my equipment in photos.
I had decided that it's about time for me to introduce him to a better sound appreciation that his MP3 files on PC.
I want to stay on budget and specially size wise since its difficult to pass electronics trough Cuban customs without paying fees.
My thoughts are.
1-PS audio Sprout 
2-NAD 3020

Both small and loaded with features.
I have no choice of speakers yet. Thinking on ELAC B5 or B6.

Headphones, I haven't decided yet.

I would really appreciate your inputs.
Kind regards.
Thanks
