I'm not really contemplating going from the GH's to Accordo's.
Right now in my system, I very very seriously doubt that the Accordo's would compete with the GH's. The Accordo's might compete with Olympica's, but they would have to be miraculous to out do the GH's.
Frankly, it is somewhat amusing as to why people who have never heard a pair of well sorted GH's, can even believe that almost any other stand speaker in the world has much of a chance against them!
I posted the thread to see what others thought, but personally I have no intention of going sideways....never mind backwards, LOL.
