Stand Alone Super Tweeter for Revel F208?

I feel like the Revels could use more air. Things like triangles, bells etc. are there but they aren't as sweet as the other speakers I mentioned.

A friends B&W 802D2 has that sparkle I'm referring to as well. Ringing tweeter also?

Or the woofer warpage!

I have an Audible Illusions L2 tube pre now. You are correct. The Revels are more natural. They do everything. I guess I'm looking for high end that is not strident but detailed and midrange that is sort of polite and doesn't hurt when you turn it up. My cousins B&W 802D2 has a midrange and high end I like. I have tried so many speakers. KEF LS50, Tannoy XT8F and XT6F, Spatial M3, Golden Ear Triton 2, Dynaudio Contour S3.4, Totem Hawk, Gallo 3.5. Frustrating.

I tried the Schiit Loki Eq. Fun for a minute. Then reality sets in. 

Do those HFTs work? Wow!

Update- I bought a pair of Taket Batpure super tweeters. I wasn't even sure if they were working. I would try with and without and it seemed sometimes I could tell a difference and other times not. I have had them connected now for a couple of weeks and decided to disconnect them last night. Everything seemed flat and lifeless without them. If you connect these things by themselves you can't even hear them!
