I have auditioned both the Ref 1 and LS-25, but never the LS-16. I can tell you that the Ref 1, in my opinion, was much better than the LS-25. I found it to be significantly more open and detailed. If you want other opinions, check out www.audioreview.com. There are quite a few reviews of the Ref 1 on that site. Hope this helps.
