Nice upgrade to Hales T5’s

I have a pair of Hales T5’s with upgraded crossovers and upgraded Seas Millennium tweeters. I actually love these speakers but for the sake of conversation and a possible one day move what speakers would be a nice upgrade to these modded Hales? I just recently had the speakers repaired and measured and they are in excellent condition. I ask for fun as my Hales sound really good but for the hobbies sake what speakers would be a nice upgrade. My amp is a Pass X250.8 and my preamp is a Pass XP-32. I am using a PS Audio Directstream dac with a Perfectwave transport and an Auralic Aries G2.1 streamer. From what I have read Joseph Audio speakers look interesting as do Magico and Vandersteen. I truly do ask out of curiosity as I believe my Hales T5’s to be much more valuable than what I could get for them on the used market. I’ve invested approximately $1500 to each speaker in tweeters and crossovers.
