No? Take a look at the prices I listed. The Bowers & Wilkins Diamond 800 is only $15,000 - $25 000 depending on the store/date they were sold. There are probably more than a 100 speakers that cost more than that. Yet I put them on the list as many have claimed it is the perfect loudspeaker. Though very arguable. Same goes with the Revel Ultima Studio 2. $12,000 is significantly cheaper than some of the $100 - $300 000 speakers you can find on higher hi-fi etc.
As for your question... I would rather tell people I have $500,000 speakers if they truly were the greatest speakers ever made.
Did you create the list by price alone?
My vote is for the Linkwitz Orion3. Mine aren't done yet, but I have everything save for cabinets. Those will get done (hopefully) this year.
Still, they'll run me about $5,000. If you have any doubts about them, visit the Linkwitz Lab site. I haven't seen any speaker so thoroughly documented and tested. Linkwitz truly knows what he is doing. He set out to create the best possible speaker and turned it into a DIY build so it'll be as affordable as possible. This is the best that one of the preeminent audio engineers could do. No audio jewelry, no snakeoil, and it certainly doesn't bow to conventions.
Aside from that, I'm happy with the Quad ESL-63. It doesn't get the lowest octave, but those things can turn out square waves accurately and certainly sound like it. You can get used pairs in excellent condition for $2,000 or less. I doubt any of those five and six figure speakers would better a good pair of Quads.
As for $100M in discretionary cash, I'd keep the Quads and have some nice solid black walnut Orion3 cabinets professionally built for me. I'd use the rest of the money to gobble up a bunch of rental units. Figure I could pick up about 2,500 units and collect roughly $2M a month in rents. Then I'd travel the planet, attend any concert that interests me and drop around $500k a month into charity, scholarships, and angel investments in small companies. The universities I attended would get many more endowed chairs, too.
Yeah, I could spend $500k on speakers. But that could also get a company off the ground and create jobs. It would also put people through college without evil student loans.
And I'd still have a stereo as good as anything out there. Maybe not the bragging rights, but who cares? Would you rather tell people that you have $500k speakers or that you created 20 jobs last month?
