Forward thinking Audio setup

After a bit of research, I'm tempted to go for this kind of setup:

1) Wireless RaspberryPi with xbmc or raspify
2) Cambridge s30 speakers
3) Scythe Kama Bay 2000 Revisione B amp
4) Hifimediy Sabre USB DAC 2

All this will come to around 350 euro and i believe will give me a good starting point for a versatile audio system.
What do you guys think?

Thanks for the suggestion . I had those in mind too. They'll most probably be part of the setup
