From my research, I understand that Dolby Volume performs the same function as Audyssey Dynamic EQ + Dynamic Volume. Is there anyone who has used both of the technologies that can tell me which one functions better? I have experience with Audyssey Dynamic EQ (works great), but am considering a unit that has only Dolby Volume. I want to make sure that I'm not giving up any functionality by going with a unit that has only Dolby Volume. All comments are welcomed.
