Hifi Rose Recommendation

Hello,
I’m interested in purchasing a Hifi Rose streamer that best fits my current setup. My sound system is run by a Yamaha amp which also has Samsung TV, blu-ray and Apple TV connected. Which steamer would you recommend for me? Also, all my music is on iTunes on my computer which I can listen to via Apple TV. Would I be able to listen to my iTunes collection on the Rose or would I need to transfer my music files to the unit? I’m looking for the best sound quality opiton.
