There's a discussion of the differences among current Denon receiver models at the top of the forum thread dedicated to Denon E and X model receivers. See http://www.avsforum.com/t/1465528/the-official-2013-denon-e-series-x-series-avr-model-owners-thread-faq#post_23134186
The major advantage of the X2000 is that it provides a higher quality of Audyssey (XT) than the X1000 does. Many people believe that that alone is worth the additional $100 or so.
Refurbished failure rates seem to be about the same as the failure rates for new units. Some units were returned because the owner didn't understand how to get them to work. Others had real failures which were fixed. Some had failures which couldn't be reproduced, so they weren't fixed.
If you call an authorized D&M reseller, they'll quote a much lower price than the X2000's MSRP (~$650), which is all they're allowed to advertise publicly. The warranty period is at least a year longer for new units than for refurbs. FWIW, AVScience, the primary supporter for the forum, is an authorized reseller for most major brands of home entertainment equipment, including Denon.
I hope these comments help a little.
