I always enjoy a arguement that uses Stereofool as a reference ( after all all those advertisers can't be wrong!!). The diode effect does work on concrete floors since I've used both points and the Sistrum 101 stands throughout my system. What they are cpaable of is stunning for both products, the pionts are a good value( a friend just bought 1.5 audiopoints for his Totems and was schocked at the difference they made compared to stock.)I also liked the points but was able to afford the Sistrum 101 whish I use for all my components, I also purchased sp-1's for the speakers. This gave me staggering dynamics as well as a big increase in resolution, detail and speed. So if you need a cheap tweak call 1877-668-4332 and talk to Robert. If you don't like them I am sure that you may send them back, if you can !! Take care Dennis
