It is challenging to find a decent place to audition anything these days. And even when you find a place, the acoustic is usually suboptimal.
IMO the best place for audition is in a real home environment, not some stores. So just listen to the Aperion and try your best to compare to the Revel. Comparison from memory isn't ideal, but it's better than nothing.
Really, it's a matter of very subjective opinion. Some people may prefer the Aperion. But I think most people will prefer the Revel simply because it is Revel.
The Revel has more prestige and resale value. Some people may extrapolate some similarity traits and "DNA" to the $22,000 Revel Salon2, which is considered by many people to be one of the best speakers in the world.
In the same way, people may associate many KEF speakers to the KEF Blade.
And some people associate the RBH SX-6300/R tower (MSRP $3280, street prices lower) to the $50,000 RBH Status Acoustics 8T speakers.
