Although certainly not high end (more mid range), this model would certainly work well, although note the version of YPAO it uses cannot EQ the subwoofer whereas the next model up, the A2030 can. You may also want to consider the Denon X2000 (on clearance) with Audyssey MultEQ XT which can EQ the subwoofer and which would allow you to put more money into better quality speakers.
If you are really serious about 4k it would be smarter to buy a 2014 model that has hdmi 2.0. Upscaling is probably best handled by the tv. Give a realistic maximum budget for each item for best results. Comparing a receiver that costs 3 times as much is not rational. Better to have too many amp channels but the price goes up a lot and not required. Speaker questions go in a different forum for the most part.
i was looking through some recievers and i have seen that Onkyo is plannign to sell Doly Atmos sound system recievers. Can someone please suggest me whether the below 2 recievers are better then the Yamaha one which i have kept in this thread ?
Just in the last few days the game has changed. Dolby atmos 3 dimensional surround sound has been announced by all the main players. Onkyo is dropping any audyssey room correction because it requires twice as many audio processing chips. Denon and Marantz doubled the chips at great cost. What is the realistic maximum budget on the receiver? Same with sub and speakers?
A 9 channel receiver will have more connections and/or features than a 7 channel receiver. You don't have to use every channel. They cost more too. With atmos you will want more speakers. Mainly 2 or 4 more in the ceiling. Nothing fancy though. None of the hdmi 2.0 with dolby atmos receivers will be out for a few months. When are you ready to buy?
