Yeah Dave just said the sensitivity of the two is about the same, so they should seem about the same level when you compare. That's good - it makes your comparison fair without you having to...

In some posts you argue for measurements. Yet here you're saying these speakers are particularly 'transparent' and your only evidence is that...

Who said blind test is 'scientific when regards to measurements?' I'm not even sure what that means.

But if you want to know whether there is an audible difference between two measurably...

White papers are marketing material. They're no different than TV commercials, except they have a different format and a different target audience.

Also, you might want to set up the speakers so that it's AB AB, instead of AB BA. In other words, right now you have the Arias both inside and the Ascends both on the outside. So the Ascends are...

That's a fairly large room.

How far away from the speakers would the primary listening spot be?

Is this primarily for home theater?

Do you want to be able to listen at pretty loud levels...

Whether the KEFs could beat the Revels in a blind, level-matched comparison *might* just come down to the room they're in. How wide is the room? How much absorption on the sidewalls?

Yes, I'm aware of those. That's why I said what I did - that there are pros and cons to each speaker. Revel wins some measurements; GE wins others.
