I purchased this unit hoping it would replace a home theater receiver, but found the limitations too great.
I was pairing this with a Sony Bravia TV, using the HDMI interfaces. I found the HDMI audio to be 1 second delayed with only 1 adjustment option on the amplifier for 'Sync Video'. Setting this option to 1 caused the audio to be 2 seconds out of sync, instead of 1. When using the HDMI and ARC #Audio Return Channel# feature of the HDMI, this was more prevalent. If I was using the TOS interface, I did not notice the delay problem, but lost the auto switching ability, and have extra cables. In addition, when using the ARC, almost all the audio options are disabled in the TV, relying on the audio controls of the AV system, which are sub-par in the the CT550W. They're ok, but not great. According to the manual, the system would choose the correct sound field automatically, but all I saw was 'standard', and rarely liked the sound field. #IE: Playing Pandora should be 2Ch Stereo, while Netflix should Probably be movie, but if using ARC, this is not changeable by the user# Using TOS, the TV provides the options, but disables the auto speaker disable, resulting in a very poor audio echo if the TV speakers were not muted.
