NoiseStop System (sound absording material )

I can across this site yesterday ... was wondering if anyone has used any of the products here for "audiophile" purpose ??
Was wondering if this is a cheaper option to treating listening rooms ?

Please share your experience

Sound absorbing methods may not be entirely a good way to treat a room. Think : energy losses(absorbed). Would letting the sound bounce a wee bit be better? Anyone to explain? What ever will happen to the reverberation time, if most if not all the energy is absorbed?

A combination method of absorptions, reflections and deflections? Does sound like the work of professional people setting up an acoustically friend room for a very rich client!
