rosami, while there has been some incremental improvement (IMHO more hype than substance) over the years in speaker design, I still think the real value is with some of the older stuff. Some of the great designers, like Jim Thiel, John Dunlavy, Peter Walker, etc., have past, and there hasn't been a stampede of newer one's jumping to take their unique places. If you like Thiel's you might want to check out offerings from Duntech, Green Mountain, and Vandersteen. I suspect the next generation of speaker design on the horizon might be a bit different with more internal DSP functions. Time will tell.
