Isn't it ultimate about the prices (in relation to performances & availability) ?
I mean if the price difference is insignificantly, I think everyone would want to buy from a local store.
But who is going to pay $4K when they could pay $2K?
If you believe that a particular ID speaker sounds better than B&M, then why buy B&M even if it is less expensive?
If you believe a particular B&M speaker sounds better than ID, then why ID at all?
So it depends on availability, performance and price.
The value of money varies greatly among different people.
I know a lady who deliberately buys things at top price so she can brag to her friends about how much she spent on her new hat (or whatever). She is married to a very successful doctor (on the order of $400 to $500k/yr), and that is her comfort from the fact that he is a workaholic and essentially never home.
But most people with a truly large income are going to call a custom installer and essential say "take care of it". Unfortunately, these custom installers usually are quick to focus on in-wall and in-ceiling speakers (because most of their customers want sound "coming out of nowhere").
Here is one of few custom installers I know of that uses free standing speakers a lot. I suspect some of their rooms cost a scary-high percentage of the cost of my home! Check their slideshow at this link:

More commonly, we get people in the lower 6 figures who, knowing this is a once-in-a-decade purchase, won't flinch at spending
extra $$$$ for the convenience of:
1) Not waiting for shipping
2) Quick resolution of any DOA or defective gear
3) No worries about shipping damage, damage claims, etc.
4) Not spending time trying to find the best deal (price shopping is, after all, a largely clerical task)
5) Having someone deliver and set it up.
In some cases, they appreciate the attention they get by being a serious customer of a smaller local audio store, they can call the store and they will be remembered by the manager on a first name basis and know they will get quick resolution to any concerns (partly because the manager knows he will pay for it if required).
Naturally, we would never see these people here.
People who participate in an audio forum are some combination of:
1) Have a passion for music-audio-SQ and enjoy sharing that passion... especially with like-minded folk.
2) Are looking to get the maximum benefit out of their budget (if this is their only interest; they come, get advice, and move on once their system is complete)
3) Enjoy finding/sharing great deals.
4) Have no real life (in the cases of Adam and Alex2507)
