audiophile home listening room

people getting favours from friends in the industry so it won't be long before the official "Abbey Road" PRIR has competitors from a "Cathedral Lane" PRIR ... that's just the way things go.
Being able to compare different listening environments is one of the big selling points of this to me.
Post #677 and the copyright mention the owner of the room, either recording or mixing rooms in professional studio or the listening room of an audiophile friend.
AFAIK only very rare audiophile listening rooms have the same level of isolation and internal acoustic treatment than good quality professional studios.
An audiophile is not forbidden to donate his PRIR or allow a PRIR measurement for free and authorize free distribution of the BRIR for other users.
I just feel that the user being measured must carefully explain the owner what is being measured and the potential altruistic/recreational or commercial use that PRIR may have.
Personally, I would like to have a HRTF in a PRIR envelope, as
arnaud already mentioned early in this thread, preferably in an anechoic room (which may be more difficult to reach than any studio or audiophile room).
There may be a difference between the recording venue/room and the mixing/mastering room.
But I do agree with you that the liberty to choose different flavours from different reverberant rooms is a selling point to be praised.
As you say, I don't doubt some users paying substantial amounts for measuring a PRIR or personalising a BRIR from the mixing/mastering room of a world famous studio.
But who is going to internalise that imaterial value? The owner of the studio or the member of the staff that did such "favor"?
