Stand Alone Super Tweeter for Revel F208?

Yes, the HFTs work -- the SR room treatments are a very effective way of dealing with even an under-treated room but they can also be used to optimize and fine tune a well treated room (like my setup)

They're cheap (or you can even DIY, search the 'Gon) and available on 30 day money back

Why not get the Bowers Wilkins ? You know you like them .

Almost forgot, try two things. Try toeing the speakers directly at your head, and also, try listening below the tweeter axis and above it. It's quite possible you will like the sound better with the speakers tilted, or your seating lowered. 

Best,

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

If a driver cone sounds like the material it’s made of, as is the case with many speakers mentioned here, then yes (yeah, yeah, I'm well aware of cone breakup measurements...) I’ll call it "ringing" since that’s what it sounds like to my ears. You can call it "sparkle," but I believe what you’re hearing is the inherent properties of cone materials masquerading as extra detail. That’s great for selling speakers to home theater buffs, not so great for long term musical enjoyment.

I've seen stand alone Air AMT tweeters at AliEpress.  There are 2 different versions.  Both versions in external enclosures, with binding post connections and level controls.  So, simple enough to try.
