How important is it to have audio signal delay?

[jasmit]

Are audio/video syncronization problems prevalent enough to influence a decision on purchasing a receiver? Or, in other words, is it a "must have" feature?

I had just about decided to buy a Denon AVR-2805, which boasts audio signal delay, when I happened to see HK AVR 330's on sale at CC for $499.00. Of course, the 330 does not have audio signal delay, but that's a very attractive price from an authorized dealer.

I realize too that there are other differences between the Denon and the HK (the Denon is more feature-laden), but they both seem to be well-built receivers which contain all of the power and connectivity I need. I guess the oversimplified question is, "Is audio signal delay worth $400?"

Any thoughts would be appreciated.
