I've read a recent thread which seems to be trying to do the same thing as me, here: AV receiver and stereo amp into same speakers The response at the time was to use a speaker switch. I think i have a far simpler option, but want to run it past the experts before i fry something nice. My set up is in my sig: Hifi speakers are MA Gold GX300. My amp is the Cambridge Azure 851N. The Av amp is an RX V673 and my 5.1 AV speakers are Kef eggs and a wharfedale sub. I don't particular want the hifi on when watching films. The amplification on the 673 is adequate for our tastes. Also the 673 doesn't have a pre-out, so using the hifi amp with the av amp doesn't appear to be on the table. But i would love to use the GX300 as front channels for AV, instead of my Kef eggs. The back of the GX300's looks like this. So my question is, as i'm not bi-amping, the HF and LF are connected. Are there not simply 2 sets of speakers posts for both L and R channels of the GX300's? If so, why can't i just add additional speaker cable runs from my AV amp front LR channels to the other posts on these speakers? I won't ever be running both sources simultaneously, and i would need to reconfigure the AV amp to recognise full range front speakers. Additionally, for a Brucey bonus, it would free up the 2 Kef eggs currently running front L&R, that i can then use for the last 2 channels. It seems so simple, i must be missing something. Can anyone advise please? Thanks in advance.
