Let's bring this back to the foreground. I'm not surprised that it is sitting quietly now; there are enough cautions that many will not try it. I suspect that only the most adventurous have done the Schroeder Method. I also suspect there are others who have tried and not reported back yet.
Meanwhile, the results have gone from wonderful to astounding. I just put together a Schroeder Method XLR with Clarity Cables Organic ICs and I'm astonished at the result. I'm building better and better systems with it and there seems to be no limit in sight for improvement of the sound.
