Roger was designing stats even before Gayle Sanders and Ron Logan started Martin Logan.
Make sure you try the 10C. You will find it one of the most transparent you have ever heard above 200-300 Hz. Below that it is OK and still needs a sub. One problem with these is a very narrow sweet spot. Also, because the stat panel sits above the woofer and your ear height is not at the vertical center of the stat panel, it tends to unnaturally raise the soundstage in height. They are exteremely revealing of the electronics in front of them. Would love Roger to build a 6' stat panel with separate woofer section--that would be incredible.
