Hi we are talking different levels of scale Ron.
I think stats are excellent on a VFM perspective. What you get from Acoustats and Quads, is impossible to beat until you reach a certain level. I have yet to hear a smaller Apogee I liked, and each restore sounds different. The Analysis Omegas sound better to me, when modded, than corresponding Apogees. But then you get the Full ranges, which restored by Henk sounded delightful and well over any stat or Analysis I heard, and costing, actually, the price of a Summit. And I have yet to hear well-restored Divas. Then is the jump to the big league of the Grands, and these German Physiks retail at more than twice the cost of the grands, though their street price will be closer to the Grands. And there is a whole raft of horns in between, each one sounds different, so I really cannot treat a Horn as a generic category.
For your transparent tastes of stats and MBLs, the Acapella is similar. My taste, as you know, also requires fullness and density, which I find in Apogees, and Detlof's GP had it in spades. You should know that Henk's Apogees were driven by much lower level of electronics compared to what I heard today - difference being roughly the cost of the GP itself. That said, I think the GP are capable of better mids. For a room the size of Detlof's it is a no-brainer. Apogee Grands just won't do well there. In a bigger room too, the mids between the speakers due to the way those midbass drivers center it in between, will probably be better. But then the Grands will be faster and slammier and I love their integration.
The WE 16A will still remain a special speaker, because what it can do, nothing else can.
I really don't know the answer to how Detlof integrates the Plasma tweeter, but it does not come into play much. He said it does during jazz.
