Has anyone successfully used a Windows 8 tablet to stream music using iTunes & Airplay?

Iíve just purchased a Linx 10 running the full version of Window 8. iTunes seems to work well. Tracks play fine through the tablet speakers, but when using Airplay to stream to my Marantz MCR603, it cuts out every few seconds for about a second, then starts again. My desktop PC and laptop both have no problems streaming using Airplay on the same network.

Any idea have to resolve this?
