I own a G68J and want to listen to Dolby True HD titles without replacing my G68J. I know that I could get a Bluray player with internal Dolby True HD processing and feed it to the multi analogue inputs on my G68J. Let's call that the default set up.

In what way would my Dolby True HD listening be improved over my default set up if I were to introduce a HD621? I assume the HD621 does not decode Dolby True HD internally?

Sorry if this is asking a stupid question. I am trying to figure out whether I should order a HD621.

Many thanks
