"The Ultra High-End Speaker."

Mahgister-what makes you think you are the only 1 that knows certain things? For most of us that spend tens of thousands of dollars on gear, don’t you think these same people know how to treat their room? The room is a must to do right first. A good treated room can cost many thousands of dollars. But the thing is, even if you spend tens of thousands building your room with all the acoustic treatments with the right dimensions, a cheap stereo will still sound cheap. But this same room will allow your better equipment like the Revels the OP has, to sound their best. It would be foolish to spend thousands on the room if you have cheap equipment, but at the same time, it would be foolish if you didn’t do this if you have good quality equipment, like the Revels. 

It depends on room size mainly. Larger rooms require larger speakers and larger good quality speakers cost more.

$24K for speakers should be able to do it in most cases if spent wisely. More cost may or may not yield some marginal improvements. The devil is always in the details. The Revels are very good quality and a very fine choice.

Speakers must be more than excellent but it's not the speakers that take the system to the reference level, it's the source and the amps.

Here’s an example. In a smaller room it is hard to fault the sound quality of a pair of tiny kef ls50 metas plus a good quality sub. But that is only within their limits which is mainly how loud they can go without distortion.

So for around 3K properly setup in a smaller room you can basically have all there is to have up to say 85-90db SPL or so.

Now some might want to go louder and some may just not care for the sound. But the sound is without question technically very high end.

As the room size gets larger so will the cost of best possible sound. But a pair of $32k Kef Blade metas can do the job in most any room found  in most people’s houses.
