Thanks for your suggestions. I attach a pic where you can see the location of my Elacs. I have also 2. floor rugs, one large and one small. Then who are the curtains on the right and 2 fabric sofas. Under the speakers I often have a carpet panel.
I never make a AccuEQ test with microphone. I don't find the original mOnkyo mis. Is it important this test?
It's a nice room, but does look like it may have some difficulties. Have you tried moving the speakers out away from that fireplace and closer, or more evenly arranged to your listening position. I know it's not cool to do so now, but I used to have to move my speakers out when I really wanted to listen critically, and this was the beauty of smaller speakers. For more ambient use, your convenient and away layout is fine. But I would try a more near field approach when you really want/need to hear dialogue. It takes very little effort to do. From here, I would experiment a lot wit placement, even that which is temporary.
I know you said you are now happy with the sound, but I would still try different arrangements.
ETA: Is that sofa position based on the optimal viewing of that screen? Very rarely do the sweet spot for the audio and video end up in the same place. Of course the video is much more forgiving but, people tend to have a preconceived viewing distance comfort zones and they have to be forced to adjust. In other words, if you haven't already, see if you can notice a natural sweet spot based on how it is set up somewhere else in the room. I have a natural (and a really good one, if not the best) one at 8ft from the front of the speakers faces, which are about 24" from the wall behind them. But that is not where I wanted to sit. I ended up optimizing for near field, just a few feet back from the speakers, in a more studio-like arrangement. Nobody else cares about sound quality here like I do. Therefore, anything unfavorable behind me just ends up outside of my concerns. Near field, when implemented correctly, ends up a bit more 'head-phonic,' and is often a better way to learn the capabilities of your speakers, if nothing else.
