thanks very much for your response. Copy that on not extracting the audio from the projector - my bad! I'm going to be placing the blue-ray player & playstation at the back of the room next to the projector with the amp at the front under the screen. I've changed my plans a little and am hoping to go for a 4k projector. So i will HDMI out of the source to the projector and then hopefully find a way to send the audio wirelessly to the amp. Can you recommend any good wireless audio HDMI or optical out senders, I found lots online, all varying in price. Will audio quality be effected much and are there likely to be any sync issues?
Thanks very much
