Hi, thanks in advance for taking the time to look at this. I am trying to add a 2nd receiver/amp to power 2 larger speakers that I would like synced with the 5.1 system. I already tried splitting the stereo jack and running it to the 2 power sources, resulting in an echo that was much too apparent. The LG is putting out the sound slightly behind the bare-bones NAD amp. The only outputs on the LG 5.1 are the Y, PR, PB, Monitor and HDMI. From my very limited knowledge + google + trial and error, it appears my only(possible) solution may be to purchase an HDMI digital to analog converter and try running the audio from the HDMI out to the NAD amp. Any input would be appreciated, thank you.
