Page 50 of your receiver's owner's manual has a reference to "Audio Delay" which can be set by the user. So, yes, your AVR does have the ability. Above all, you really should read through your owner's manual. AVRs are complicated devices (although not as big as they used to be) and if you are truly concerned about the sound quality, then that should be first on your list. From your responses I can tell you don't have much experience in this area, so try to learn about the AVR before making more changes.
If you really did what you wrote, can you still get DTS-HD from Blu-Ray discs or are you limited to 2-channel audio? Your AVR display should indicate DTS-HD when a DTS-HD disc is playing.
After you read through the manual, if you have other questions you can ask here or in the VSX-53 Owner's forum.
