Many decades ago, I had a pair of ESS speakers with AMT tweeters that were initially dramatic but ultimately disappointing. These turned out to produce sound that was mostly "boom and sizzle," with poor integration of the tweeter and woofer. I was very happy to move on to more satisfying speakers, and I lived fairly happily for many years with the metal dome tweeters in a pair of Thiel floor standers.
More recently, I replaced the Thiels with PS Audio Aspen FR10s, which have very sophisticated planar-magnetic tweeters and midrange units. These speakers have a very clear and natural sound that is sweet, smooth, and realistic. I consider these to be significantly more satisfying than any AMTs or dome tweeters I have heard. Take a look at the many positive reviews online.
The FR10s are definitely in your price range, as would be a used FR20 pair. PS Audio offers some trade-in deals on new speakers as well as 60-day in-home trials.
