You guys aren't giving them a chance, it's definitely worth it! There's a lot of labor involved here. I mean, look at all that flex sleeving and shrink tubing, not to mention twisting the wires! That probably took the guy a whole afternoon to finish.
Look at it this way, in a surround sound system you could sell off some of your extra speakers, cause the cables will provide the "3D" effect! I dunno, it looks like a bargain to me.
