@fleschler Great point about the cost of the room. I would think that anyone who has the ability to buy the mega $$ speaker would have a room that could accommodate it. Not just from a size perspective ( although this is a given) but also from the acoustic requirements. This may be an assumption that is incorrect, as I suspect ( and I have seen a few poor room set ups with very pricey gear) that this is not always going to be the case. If one has a budget like you stated, then i would think that putting the bulk of the budget into the room and its acoustics will pay greater dividends than just about anything else. As you describe.
Question is what your friends very nice YG’s would sound like in your room?...I would guess that you would be tempted to pass on your Legacies then!
