Comparing Ribbon Tweeters - Golden Ear vs. Ascend Sierra

You should try to listen for yourself. Speakers are so subjective and everyone has different preferences. I've heard Golden Ears and don't like them, but my current speakers use an AMT ribbon tweeter and I love them. In my opinion my speakers are detailed, dynamic, and non-fatiguing. My point is it's not only the type of tweeter, but how it's implemented. 

I love good AMT’s, but the range of quality in the tweeters and their implementation varies a great deal. The Golden Ear loudspeaker I heard with AMT tweeters was among the very worst I’ve ever heard.

In terms of tweeter brands, I consider Raal (true ribbons), Mundorf and Beyma (AMT).

There is some debate as to whether some true ribbon tweeters add a little distortion and coloration we find pleasant. An artificial sense of "air." 

If you are interested in the parts, more than the speaker brand, I suggest you talk to Fritz. Great speakers with top notch parts at very reasonable prices. http://www.fritzspeakers.com/

If you must have a Raal, Selah Audio has a long history of speakers with them. http://www.selahaudio.com/

The Beyma tpl-150h is a very good sounding amt driver and would make a excellent replacement for a certain 7 tweeter array that’s popular.

I do like it better crossed a little higher though,2k to 2.5k with a really nicely built single order 6db crossover.

Ribbon and amt tweeters can be really good or really bad depending on the rest of the speaker implementation.

Good luck in your search,
Kenny.
