I have never tried this brand, but I used a splitter from ART for a little while till I discovered it colored the sound. Now I mainly use Y cables for this purpose. (with both outs of the y going to either a mixer or preamp.) Even though the splitter I tried was no good, perhaps better ones will properly do the job. I just don't know at what $ cost.
Radial Engineering is a highly regarded manufacturer of signal interfacing products. Based on my use of other Radial products, and ART products, I'd say Radial is an order of magnitude better.
