Hmmm...I always thought it was slight, I am going to do some A-B testing tonight to be sure all my settings are correct.
I'm currently decoding it through my PS3 and sending it (via HDMI) a PCM DTS HD MA or DD TD signal to a Marantz SR8001 using as a processor.
Times like this I wish I knew an audiophile personally that can help me test my system!
