Lots of info offered some pretty good, others not worth the time. We are a manufacturer of audio components and have been doing equipment repairs for 25 plus years. We have heard more equipment than probably everyone posting here combined. That being said:
Forget Harbeth 40.2 - consider the Revival ATALANTE 5 speakers at around $5K. Better sounding in every way.
I am also hearing very good things regarding the PMC speakers from a very good source although I have not heard them yet. I was not a fan of the old designs.
The other speakers I would go listen to would be the Vandersteen Quattro. You can get amazing sound from them even against setting them up against the wall. That can be helpful if your wife is involved in this decision, etc.
Happy Listening.
