The HALO is a good amp that is capable of driving most speakers available today regardless of impedance. So there are literally hundreds more that can be recommended.
All the speakers you have heard so far have metal tweeters. So why not go out and audition some models that have soft dome tweeters? After all, the goal is to find the speakers that sound best to you; not us.
Some brands that come to mind are Dynaudio, Vienna Acoustics, Sonus Faber, etc. You may find that these types of speaker have a s sound and response that you like, especially with vinyl. But you have to hear them first. Good luck to you.
