I was wondering, before purchasing the Airport Extreme Review: Apple's AirPort Extreme is a safe choice | Macworld, if it was possible to connect my 3 Sony Airplay speakers https://esupport.sony.com/US/p/model-home.pl?mdl=SANS310&LOC=3#/howtoTab to the 3 LAN Ports of the Airport Extreme and airplay simultaneously as multi-room audio from my Iphone without using iTunes ? Thanks for your cooperation. Regards Oliver
