I dont really consider the fact that the Thiels require powerful amplification a flaw, more like a characteristic of the speakers. Getting the cables right is a major part of really enjoying the Thiels. They will show the true character of cables like no other speakers I have heard. I have tried many any have settled on the Audioquest DBS cables from start to finish. Right now I have Panthers from table to phono and from phono to preamp. I've got Cheetahs from CDP to preamp and preamp to amp. I'm using Mont Blanc speaker cables.
