Thank you very kindly for your most appreciated help, dear experts.

Are you interested in providing us with the dimensions of your room?
By not providing any "boundary conditions" I was hoping for a wider spectrum of responses... Anyway, here we go: my listening room is only about 24' x 12' (8' ceilings). By positioning the speakers along the shorter wall (let us say, 3' - 4' from it) and 1' - 2' from the respective side wall, I can establish my listening position 8' - 10' from each speaker (thus forming classical equilateral triangle).

... 10 to 11ft back for listening position ...but I personally prefer a bit more away for the seat.
10' would be close to my limit, probably...

1. I've owned three pair of Daedalus now. They seem to be less fickle about set up than most.
3. ... That said, like most speakers, the farther out into the room the more realistic the stage will be. In Rooms 1 & 2 the speakers were 12-15" from the rear baffle to the wall behind. Sounded good. In Room 3 the speakers are 30" from the rear baffle to the wall behind. Sound better!
4. Like most speakers, the greater the distance from the side wall reflection point the better. In Room 2 this was only about 1.5 feet. In Rooms 1 and 3 the distance is more than 3 feet. More is better but Room 2 sounded darn good.
5. Room behind the listening chair matters. In Room 1 my head was against the wall behind. Bass was not as clear, had some lumps, more perceived bass than in Room 2 or 3. In Rooms 2 and 3 my head was 1/3 into the room and at least 6 feet from the wall behind. Bass is much smoother, cleaner, less perceived bass but actually tighter and deeper.
6. In all three Rooms I used the "Get Better Sound" triangle recommendation (distance between speakers is 83% of distance to ears). This has worked well for me over the years. Minimal toe in since the baffle is angled.
I am just in a small condo, guys! I simply cannot see how I can accommodate the above recommendations... Just one option comes into consideration: 4' from the back wall, 2' from the side walls gives me 8' between the speakers, and, therefore, listening distance should be about 9.65' with at least 8 feet from the wall behind...

... My DA-1.1's had a driver array that covered nearly the length of the baffle and so there was a minimum distance that you needed to honor in order to give them the opportunity to cohere. It was some time ago but I believe around 6-7 feet was sufficient. With the clustered driver array of the Apollo's, very little distance is necessary and as such they are much more appropriate for a near-field type setup but will also fill the room when seated further away.
Do I understand correctly, around 6-7 feet (or, quite possibly, even less?) should be sufficient for the Apollo drivers to cohere, please?

I have Apollo 11’s. My ear to tweeter distance is 12-4”. With this MTTM array I’d say 10 ft. Is the minimum distance. Inside this the overall results may not be optimal.
The Apollo’s drivers should integrate much closer per Mark’s comments above.
I am lost: is it 6' - 7' or more like 10' for the Apollo drivers to "integrate"? As you can tell, I am not a Guru, and need all the help I can get...

And now a million dollar question for me: can my smallish room even accommodate the beautiful (that is how the "boss" commented on them, and this happened only once before when she admired the woodwork of Prometeo's from Xavian) Apollo’s?
Any "professional" reviews you could please recommend me to see (in addition to the one published in Part-Time Audiophile in 2019)?

As always, please chime in!
