Review on Isolator Audiophile Frequency Without Distortion by Julian Banks

I have this product and a BESIGN Ground Loop Noise Isolator for car audio/home stereo with 3.5mm audio cable. Both do a good job of removing ground loop noise. In my opinion, Besign is better in terms of sound. While the Kript's sound quality is still pretty good, the Kript's isolator seems to make the upper mids (especially the vocal range) sound more real and alive than the Besign. Also, the bottom of the crypt doesn't seem to be as low as the besign. Since Kript only downshifts to 20Hz, it seems like it also adds a bit of punch, which might make some users happier. The only issue I had with the Besign version is that the 3.5mm plug fits loosely into the socket on the subpac. It shouldn't be loose as any other male jack I have will fit just fine. So I bought Kript thinking everything could be more premium. I am in the process of purchasing another Besign isolator and am hoping the bushing will fit better this time. If not, I may need to buy something more expensive to get rid of the ground loop noise I have due to where I live.
