Have had the Mogami 3104 LS4 jumpers replacing the stock jumper plates on my Aurum Cantus M102SE speakers for 80 hours now. I got the burn-in service, which I strongly recommend. Smoother, yet detailed highs, more natural midrange, and better tight, snappy bass. A definite improvement in clarity across the audio spectrum. I was expecting some improvement, but these really made a BIG difference! The bananas fit very snug, I was concerned about a mediocre fit, but that was unwarranted. Great materials and workmanship, top notch. I really couldn't ask for more. Great company, you can tell they take pride in their craft and the descriptions of products are spot on. Anyone looking for an upgrade should get these, they produce!
