You will hear people tell you the side wall is definitely the best. You will hear people tell you that is crazy only the end wall in that room. For sure a whole bunch will tell you only spending as much money on professional acoustic consultants as your system, and maybe more, will get you there.
Been there. Done all that. Yes including paying and seeing what and how the pro's do it.
Save your money. Nobody knows. For the simple reason nobody has your ears. Only YOU know your personal preferences. And if you spent the money to build the room I sure hope you have your own reasons.
So what you do, try both ways. There's no getting around this anyway. The whole idea of speaker/listener placement is finding the best balance among frequency response, imaging, and convenience. All matter but only you know how much weight to give each of those.
This doesn't need to be that hard either. The testing I'm talking about you could sit the gear down on the floor and try the speakers each way. Doesn't have to be pretty. Doesn't have to be precise. Not at this stage anyway.
Try several positions. Listen primarily for smooth bass response, but also for spaciousness. Really good imaging requires really precise speaker symmetry, which takes time and is not what you're after at least not initially. So notice, but do not focus too much on it. Do the same both side and end walls.
Without a doubt you will find you prefer one over the other. That's the one you go with.
Keep in mind this is not the end but just the very beginning. A ton of tweaking lies ahead. But this is the process I went through, and it has been shown to work really well. It don't cost nothing but time, and you learn a whole lot more this way than anything else. Nobody ever learned a thing swiping a credit card. So go and try and listen. You will see.
