denon avr-5805 vs. denon avr-4306

[crmfmly]

Which is really the better Denon? The 5805 has 2 sub outputs. But on the other hand the 5805 is like $4,000 more and I can't see paying $6,000 for a receiver. But honestly which one really is the better one in the end? Not worrying about money. And can somebody recommend a powerful receiver with 2 sub outputs?

I've been looking at this Outlaw Audio 990 Preamp / Processor as my receiver and it says 2 channel subwoofer offset. This is probably a stupid question but does that mean it has 2 sub outputs where I can hook up 2 subs?
