Thanks and great thread and many thanks for all the posts. The RS8's do have the tone of the RS5's and I think of them as the RS5's big brother. Nothing is going to be as fast as RS5's, but the RS8 will have the dynamics and the punch.
A while ago I noticed that some of the drivers have the roller coaster type of break in and this can happen with RS8's just like the older versions I made a while back. Break in is very important and they will smooth out. A good 100 to 150 hours is needed and I always use bass heavy music to loosen up the suspensions.
