Recently I purchased a Sony STR-DH770 as well as a pair of Polk Tsi-200 bookshelf speakers and a Polk PSW108 sub. I had a budget of 550$ and with deals and whatnot, I was able to get everything under that. The bluetooth connectivity has not been working and after a lot of phone conversations, the company I ordered it from is exchanging it for a new one. A customer service rep has suggested that I take advantage of current sales and upgrade to a Onkyo TX-NR656 or Denon AVR X1300W for the wireless capabilities. Currently I only have cable and an xbone through the receiver(smart TV apps for most other stuff), so more HDMI ports is not a priority as of now.
My question is, would it be better to upgrade from this receiver to a different model, or finish my system by purchasing surround bookshelfs and a center channel?
I know the answer seems obvious(more speakers), but the service rep is adamant that the other receivers are "so much better than the one you have, and you do not have to wait for us to get more in stock to utilize your internet music subscriptions."
Any advice would be appreciated.
Thanks
