With some hesitancy, I want to just support what Ken is saying. I am a bit hesitant, because it may be my repeated enthusiastic descriptions of Ken's products which have encouraged this suspicious promotion of the Sistrum gear and Audiopoints. When I started a thread on this topic, I had never heard of Ken or Neuance, but I was really looking for help from any poster who might have tried something that did the job well, and was particularly interested if someone could tell me that Polycrystal, Symposium or some other of the stuff I had heard of was the answer. I needed this help because I live in New Zealand and the only way I can try most of this stuff is by buying it. Without digging out the original post, my recollection is that Ken's first post on the topic was a genuine attempt to help me and encouraged me to pursue the light/rigid/damped shelf approach - an approach I had already suggested was what I thought was probably ideal, but I had had no success finding such a shelf previously. Ken did suggest his own Neuance shelf, but to his credit he also suggested other products from other manufacturers that he felt were also following the light/rigid/damped idea. In a later post Ken offered to send me a used shelf for the cost of the freight, so that I could try it. I was delighted with it and when I ordered two more I tried to pay Ken more fully for the first shelf, but he refused. I outline all of this because I believe Ken has acted totally honourably in introducing me (and some others) to his product through this forum. Like he and others here, I am suspicious of the way that the Sistrum/Audiopoints has been promoted on this site recently. I retain an open mind on the gear, but I reckon Ken is giving Draudio et al some good advice on how to be taken seriously, rather than being dismissed as posting shameless self-promotion.
