I know and trust the owner, Paul Speltz; he is like we are, a serious listener, but he happens to be an EE and very smart in this field, as well.
Meanwile the designer of that old Xhadow RCA made his own new LoveCraft RCA and claimed they are even better, the good news (i just noticed that) the price is cheaper than Xhadow and they are available direct from the designer just for $80 (pair) here. I use the LoveCraft RCA on my best phono cable (Stereolab Master Reference) and i love it. Strange that each time i talk about Chris Sommovigo products (cables) his name is still new to the audiogonners, while he was in business for 25 years. I don't think that his idea to make Xhadow connectors comes from Eichman, those Xhadows are pretty old design. I think this 6moons review expain very well who's Chris Sommovigo. The reviewer is Srajan Ebaen.
