Hi everyone, I have an old setup that I would like to upgrade, cheaply if possible (around 500E) What I have : Video source : macbook air (connected to the video projector in HDMI via Display Port), sound send via airplay Airport : connected to the amplifier via jack on 2 inputs Amplifier : Yamaha RX-V350 (configured in stereo mode with 5 speakers and the subwoofer...) Vidéoprojector : LG AF-115 5.1 System: JAMO S 606 HCS 3 + titan mosscade 7.4 (wired to the amplifier) What I need : To have battery powered wireless surround speakers (because of the room) Go to real 5.1 and be able to listen music (exit soundbar I guess) What I plan to do : Video source : macbook air (connected to the video projector in HDMI via Display Port), sound send via Wifi to the AV receiver AV Receiver : would dispatch via BT or Wifi to 2 surround speakers and via wire to the other speakers and subwoofer Vidéoprojector : LG AF-115 5.1 System: JAMO S 606 HCS 3 (just front and L/R) + titan mosscade 7.4 + 2 bluetooth surround speakers (I have already a Libratone zipp, so maybe I'll buy another ?) So : Is it a brillant idea ? Does an AV receiver can mix BT (or Wifi) and wire transmission ? Do you have an entry level model that'll do the job ? Many thanks for your help, Romei.
