are the new HD audio formats worth the upgrade?

[SILVERBACK]

i`m interested in a onkyo 705 and i would like to know if the upgrade in sound from std 5.1 dts etc to the new HD formats are worth the upgrade for £600 ? will i hear a night and day difference form the norm or is it more subtle.im happy with the amp i have but if i am to upgrade i want to know i will be hearing a difference

I did and some won't percieve it as night and day.
Much more fuller , richer sound.
Less thinny.

You may need to hear it on good speakers also.
But IMO yes.
