FV, since you have three threads going here, for convenience let me summarize at this point on the other two: yes, Axiom does all the speaker break-in necessary(about one minute for woofers and one second for tweeters)during quality control testing and following this the speakers come out neutral. All competently designed receivers are neutral and to a greater extent than is possible with speakers. So, taking a typically neutral receiver and Axiom speakers which are neutral as speakers go, the net result would be neutral if the recordings and the listening room were neutral. Of course, they aren't, so you're going to wind up with various colorations and inaccuracies, but at least the receiver won't be contributing to the problem and the speakers will be contributing little.
On your connections question, neither an optical nor a coaxial digital connection is permitted(for reasons of copy protection)to carry DVD-A/SACD material. In general the six analog connections have to be used. As Curtis suggested, there's no inherent quality problem(assuming good bass management by the player or a separate device) with the analog connections; it's a matter of inconvenience because of the multiple wires. The i.link, firewire, Denon Link, etc. connection provides the necessary copy protection and can be used when both the player and receiver are designed for it(still relatively rare at this time)to carry digital DVD-A/SACD output between the player and receiver. Don't worry about additional conversions; there'll be one either in the player or the receiver. Exceptions are the HK and other receivers which Curtis mentioned which do extra conversions as part of their processing, but that seems to work out fine too.
