Hi @David A
I am in hi-fi for around 30 years. What you're saying is I was reading in Hi Magazines (like Stereophile,  What Hi FI decades ago). 
the rule of an equilateral triangle, some 3 meters between the speakers and some 3 meters sitting position from both speakers. 
Proper positioning is crucial in order to hear good sound, no need to spend words on it.
Well, it caught my interest when you said that in some positions speakers sound natural but in some non-natural. 
I was playing bass guitar for some 10 years and recorded 2 vinyls. I know very well what is the natural sound of bass guitar, drums, acoustic guitar, etc. 
Can you let us know please how you evaluate/ judge when the sound is natural? 
Thanks
Zoran

You used to play bass. I used to play acoustic guitar and occasionally accompany a singer. My wife used to play piano and we had an upright piano in the house. A friend used to lecture in clarinet at our local Conservatorium and I've heard him play in live performance. I also have one of his CDs and played it to him on my system once some years ago and asked if he thought his clarinet sounded right to him. He said it did.

I judge when the sound is natural in the same way as you or anyone else does, I make a judgement on whether voices and instruments sound the way I remember them sounding when I've heard live musical performances, particularly acoustic performances, over the years. There's no other way of doing it unless you can get a performer into the same room as your system  and get them to play/sing something which is available on a recording and do an A/B comparison of the live performance in your room. I haven't been able to do that and the recording  is always going to sound different to the live performance in some ways, especially if it was recorded in a space with very different acoustical qualities to your room.

What I said about the Sopras is my opinion based on my experience of how voices and instruments sound and you're welcome to accept or reject it. Just remember that I also said that you should always listen to speakers for yourself before buying them and the reason I said that was because the only opinion that counts about the sound of your system is your opinion. I like a system which sounds natural to me and mine does with a lot of recordings but not with all recording. If you visited my home you might not share my opinion. As far as I know there is no objective test for whether or not a system sounds natural, all any of us have is our own personal opinion to go on

We all set up our systems for our own personal enjoyment and we're the ones who spend the most time listening to our own system,  other people spend a lot less time listening to our system than we do. Would you want to change the sound of your system to satisfy someone who only hears it for a couple of hours every couple of weeks if what they enjoyed was not the sort of sound you enjoy when you listen to your system every day, maybe for several hours every day? It's my view that if you're not enjoying the sound you get from your own system then you're doing something wrong. Listen, listen carefully and take your time over it, and trust your own responses to what you hear because those responses count for you.
