    Hi there Bob, so my unit showed up today thank you. Ok so I am running HDMI from Amazon Fire TV to the HDACC then HDMI to TV. Then to get the sound I running cables from HDACC to my pre amp. I also ran a optical cable TV to HDACC. The sound is really good but I have just started to play around a bit. I set it at 385K and it sounds brilliant. Thanks again. Robert Yull, Oct 2017
