Anyone know who makes the DP+ twins?

There are three different types of DP+ twins out. The two heavy ones and a light weight one. I know one of the heavy ones is Sharp just like the regular DP twins of old, the other looks the same as the channel master quads but don't know if channel master still makes stuff since Andrew bought them out. But the shipments of the light weight twin doesn't have a name on them. They are nice and thin as well which reminded me of the DIRECTV quads made by California Amplifier. Does anyone know who makes this particular twin? I've taken the casing off and nothing is noted inside. From what i've searched, no one as talked about this. Just curious.
