At $1500 you should be comparing the receivers processors, room correction, transformer capacity or class D operation. Even a high quality FM tuner needs a good antenna in a good location to sound good. While modern receivers are terrific for HT processing they're still lacking when compared to the finesse of even a modest dedicated analog two channel systems ability to soundstage IMO.
Since my experience with room correcting receivers IMO it's more important to get the HT to sound its best. I would give up on the H/K and the Arcam for their dated connectivity and the lack of room correction. I find the drama of music videos and film as important as quality two channel playback. Incorporating HT and two channel can depend on the quality of your existing two channel setup.
Personally I have failed at any attempt at putting a display between my main two channel speakers and still maintain the degree of soundstage I worked so hard to attain. Consequently, I installed my HT in an small and irregular separate space and let the room correction do its job. The fidelity from classical multichannel SACD's has been the biggest surprise through the HT.
