Just looking at the specs for the two Denon receivers, the feature that jumps out at me is the level in the Audyssey room correction they offer. The 1913 has MultEQ, the 2113, MultEQ XT. The Onkyo 515/616/717 only have the rudimentary 2EQ which, in my opinion, is useless as it does nothing to correct the sub and little on the sats.
Here's a link that explains them;

I don't believe that the r530 receiver has any Audyssey version so getting either of the two Denon's would certainly help your current setup.. Don't waste your money on 2EQ.
Thanks so much for the reply. I have a question about the Audyssey. My brother has it on his Onkyo (not sure what version) and it made things sound worse. He ended up disabling it and doing things by hand and it sounds much better now (was there when he set everything up). My Yamaha has YPAO (I think that is what it is called). It was the same. Sounded bad after I ran it, and I had to tweak the heck out of it. So not sure I am sold on the automated EQ stuff.
On reason I am worried about the Denon over the Onkyo is 2 fold. A friend of mine had an Onkyo 606 (HDMI went out) and "upgraded" to a higher end Denon which he loves. But he did say to me that the only thing he liked better about the Onkyo was the sound quality. That has me worried a little as I want great sound quality.
One other thing I noticed is receiver weight. The Denon is about 5 lbs lighter than the Onkyo. I am not a pro, but every receiver I have purchased that has been on the light side has ended up back at the store. Will the matter here?
Also the reviews on the TX-NR616 are outstanding from professional testers. I know the online reviews have showed some issue, but a recent Firmware update shows to have fixed the issues.
The Denon also has fewer features than the Onkyo (such as MHL) which I might use in the future.
To summarize:
1) Is Audyssey difference really big enough to be a deal breaker since no automated EQ has ever worked well for me? (has there been any test with one receiver setting up with low end or no Audyssey and one with Higher end Audyssey and unknown testers pick best sound?) Concerned about the placebo effect.
2) If TX-NR616 Firmware update has fixed the issues would it be a higher end receiver?
3) Are the extra features worth the sacrifice? (In other words if the Denon is better is it enough better to give up the features?)
4) What would I be getting with the Denon over the Onkyo other than upgraded Audyssey?
5) Is the Weight difference telling a story?
Thanks for the help. Sale on both are Ending tomorrow, and I hate being in a rush

(maybe they will be extended)
