Harbeth Super HL5 plus Break-in


The following is an excerpt from the Harbeth User Guide:

"After exercising your new Harbeths for just a few hours they will be fully ready for a lifetime of enjoyment".

After going to the Harbeth site it pretty much said the same thing as the user guide but added that the supertweeter would take a little longer to break-in.
My new Harbeth's sounded the same after I put on around the first 100 hours so I believed the above until around the 120-150 hour mark I noticed (or so I think) the midrange sounding more realistic to the point of more enjoyment! I don't know if I'm actually hearing an improvement or I'm just getting used to the Harbeth sound since the 5's are my first experience with Harbeth in my listening room.

I would like to hear others that have owned or still own the Super 5's and whether or not you have experienced the same thing as me or something else.

I didn't notice much if any difference in the sound of my Super HL5 Plus since they came out of their boxes. Getting my custom stands made a difference as well as experimenting with tilt and placement / toe in.
@routeman21 You're posting as far as I can see about expecting further improvement from the Harbeths. Why? What's not satisfying? 
I have about 60 hours on 40.2's right now.  Frankly, they sounded great out of the box, but around the 50 hour mark there was some kind of fairly minor change, a little more relaxed, in the sense that I could turn the amp down a notch or two and still get the same level of presentation/enjoyment.  I'm more than content right now, but only time will tell if anything further develops.
