I'm looking forward to these. I hope they adjust the sound of the xba-h3, balancing it and adding clarity. We'll see! They seem to get that the housing needed to become more streamlined. Hopefully the bass will be tighter as well.
Actually, when I discovered all the many sets of ref1s that have had quality control problems (more than the 3 I've mentioned), I was extremely careful with the set I was loaned.
But yes, you're right. With the ref1, I did feel I was lucky they didn't break while they were in my hands.
