Quicksilver Contact Enhancer

Hi any body tryed the above, I bought the one from Xreme AV LLC, cant say that I am happy so far I know they say to be patient and wait 21 days Iam going on 5 days, It has seem to increase the volume of the sound and it has made everything sound bright at decent volume, I had my system to a point where I was realy happy, but we always wont more and the theory makes sense and I hope I will stick it out, just interested if any body else been through the same thing and was the outcome worth the wait? or do I wipe it off and send it back!they say there never had a return!
Thanks Kel
