There is only one on your list that I have heard, which is the Pioneer S-2EX. I was very impressed by its sound, and it looks great with its companion stands. I compared it to the B&W 804 Diamond and actually preferred the Pioneer, but I went with the B&W (despite a much higher price tag) because I felt the the B&W would hold more of its value over time and be easier to sell if need be. The Pioneer is not well known.
If you do seriously consider the Pioneer, be aware that sells at a much deeper discount from its list price than most speakers. I recall the list on the speakers being $7000 and the list on the stands being around $1500. A dealer offered to sell me the speakers with the stands (all brand new, not demo) for $4500 total.
