Worth upgrading?

[hagar852]

I have a STR-DG910 I baught in August and have been pretty happy with it so far.

I recently upgraded my speakers to the Aperion Intimus series. Trying to calibrate the receiver for these speakers I learned that the settings for this on the DG910 are much to be desired.

Learning of the new release of the Yamaha v663.. I was wondering if it is even worth upgrading.. I already know some of you will say yes.. I have the Sony hooked up to my PS3 via HDMI and the Sony accepts 1080/24p and multichannel True HD via PCM from the PS3.

I baught the Sony to upgrade from an older Yamaha receiver HTR-5740.. I did a lot of research when I baught the Sony and was cheaper than the Onkyo 605 I also was considering.. But hearing some issues of the Onkyo I decided to go with the Sony..

So basically the reason I am asking this question is I almost feel as though I am short changing my new speakers.. So maybe upgrading to the new Yamaha may do them justice. I also have been looking at Pioneer Elite receivers and Denon... I don't care if the receiver can decode the new codecs.. Soon the PS3 will be able to decode DTS-HD anyway... Just as long as the receiver can accept the signal via PCM like the Sony can..

Anyone with more experience with this type situation woud be great... I am still a receiver Noob in a way. I never had experience with any other brands but Sony and Yamaha.. When I upgraded to the Sony it did sound better than the Yamaha I had.. But will there be a bigger difference coming from the DG910 to a newer receiver? Maybe I will be better off with an older model Denon that can accept PCM and do 1080/24p. I have also been looking at the Pioneer's which seem very nice also...

My budget will be maxed out at 700... and that is way more than I want to spend...

Any thoughts or opinions will be much appreciated.
