Denon 2113CI + ~300 Sub or Onkyo 809 or 818 and wait on Sub

Hey Everyone,

My receiver is on the fritz and I'm trying to decide the best way to replace it before it dies. Also, I just got a house, so I can finally have a sub and not upset anyone:-). So right now I have an Onkyo SR508 powering two floorstading Athena's, an Athena center and two Athena surrounds. I have $700 to spend, I could go $800 depending on the recommendations. I have seen quite a bit of mentioning of the Denon 2113CI and I can get that on accessories4less for $400.00 and have some room to buy a ~$300 sub. Or I could forgo the Sub for a while and get an Onkyo 818 for $800 or an Onkyo 809 for $630. I'm also open to other suggestions, I've been researching like crazy and it's hard to narrow them down.

What would you all do?

Thanks in advance!!

I just saw the Klipsch RW-12D on sale on Newegg for $299.00 and I haven't seen it lower than $400.00 the past couple weeks. So I pulled the trigger on that. I may just wait and go for the Onkyo 818 in a few months. Just hope my receiver can hold on!!
