My initial response was Yes - pre-amp is required. After looking at the manual, it seemed to indicate that a pre-amp wasn't required but not explicitly. Since I don't like to give bad information, I've sent an e-mail to Creative Labs for this question regarding the Extigy. I expect that the response will be the same for both cards - that a pre-amp will be required. I could not find enough information on the Extigy to determine what the maximum gain is but I know that internal versions of the card used to be equipped with a 4W amp if memory serves.
The specifications on the web for the Maximum Audio audiophile USB, shows that the Analog Outs are variable "line level" which indicates that the output signal is at the same level (when turned up to maximum) as a DVD or CD-plyer which would not be enough to drive a power amp as far as I know. I assumed integrated amp from your post and not power amp. Had a rough evening yesterday - my apologies for any confusion.
