Help please, I have an A1SE at the moment connected to my Toshiba HD-XE1 via analog to get True HD audio etc. Would there be an advantage in upgrading to the XVA and connecting to the player via HDMI for sound? I'm mainly trying to see if there are any audio advantages. How does the amp actually process True HD, as I don't see such a decoding listed amongst Dolby this, DTS that etc? Thanks a million!
