Hi Captain,
I have not discontinued my earlier threads, this is specific for "Marantz SR-5008 AVR + Polk Audio Speakers"
I have not auditioned Denon based on reviews from different people/distributors.. Few even said that they discontinued Denon because of the technical faults that it has been having in the recent past. they recommending Yamaha or Marantz over Denon. they also said that the distributor for Denon in India, which was Pro FX, has also discontinued Denon. I am not sure how true this is..
You should spend as much time as possible to audition/demo AVR/Speakers before you actually buy. Go with what you like..
Now someone said you should also look for Yamaha RX V677 (HDMI 2.0, 4K Ultra HD upscaling and MHL support) which launched few month back.
