A friend and I heard the next potential generation of these at Newport in a Beta Test presented by Ted. Yes, they make an audible difference and you will prefer one over the other in your system. However, the one thing I was unable to determine during that test was the real need for them in the first place. In other words, are they a change that is a step forward or just a sideways move altering the sound slightly? BTW, Lloyd Walker offers his own version of this product and while a bit more money are very effective. I don't use either the SR or Lloyd's.

Anyone tried these little things on their cartridge? If so, what was the result?
